Thanks, was nice to be back in the car and back on here, although a lot quieter.

One mod I forgot, replaced all the door glass with Lexan equivalent ;)

Hello all, Happy new year!

Tech question...............

Whilst building up a new head, I wanted to make sure the Cams were correct and free spinning.
With no lifters in place, I thought the cams should spin, which they did until I put the cam cover on, then
exhaust cam spins fine, but the inlet cam became very stiff to move. Remember there are no lifters in at this stage.

Any ideas?

I have put together 4 head/cam/cover sets and they all seem to have similar issues.

JT

[merc85]

I think from memory dont you have to reuse the Rocker from the Original Engine? They wear to the cams so using a different Rocker cover can cause issues.

Sorry if you have done this haven't read the thread just stumbled across it.

Looking Smart btw ;)

That would make me think it's normal it 4 sets are have the same issues, do they rotate better with the lifter etc in place...??

Similar issues, not all the same, some are so tight I can’t turn it by hand
Not tried it with lifters in, not sure that would make any difference, but I’ll try it

Are they gasketed or sealanted normally? Not that I'd think a bead of sealant compressed sealant would make much difference tbh.

Sealant mate, but as you say, cant see a very thin layer of sealant making that much difference and if it did,
surely both cams would be tight?

[JT]

I'm told this problem is because of a warped head :slap:

[Dangerous Dave]

Oh No!

[JT]

Oh No!

this would suggest all 4 heads I have here are warped in some way
tells me that as soon as a head is removed, it will warp and be of no use, due to all the heat cycles it may go through in its lifetime

damn it!:slap:

[Dangerous Dave]

That can't be right otherwise we would never be able to do the head gasket?

Would it just "wear in"?

[JT]

That can't be right otherwise we would never be able to do the head gasket?

That's what I was thinking, skim the bottom of the head maybe, but the top????

Wear in, apparently not. The alloy will get hot and seize up, so I'm told..........?

[Blackdog]

Have you actually checked to see if they are warped?

[JT]

32955

can see a gap under the straight edge

for some reason the photo is upside down, but still.........

[Dangerous Dave]

Hmmm

Are all 4 the same then? Warped in the same place?

What is the history of the heads?

Is the block straight?

A cylinder head specialist should be able to sort it either way, being aluminium it should be possible.

[JT]

Hmmm

Are all 4 the same then? Warped in the same place?

I need to check the others

What is the history of the heads?

1 was in the car last time I raced
2 came from BT
3 came from an engine Dalhousie supplied, just has a broken valve, no need to suspect anything else
4 I think I got years ago as it was a ported head

Is the block straight?

Cams are locking up just on the bench, not bolted to the block, but I'll check it

A cylinder head specialist should be able to sort it either way, being aluminium it should be possible.

Any recommendations down south for this?

[MoleT-5R]

Have you tried torqueing one down on a block and then trying the cams in it then, funny how all four are the same..??

[Dangerous Dave]

Was thinking the same :D

Torque it down and test with a straight edge

[JT]

yes , that's when I first thought I had a problem

something is not right????

[MoleT-5R]

I've got to to rip the head off Gul's engine shortly, that one was well cooked and acting as a water pump, so I am expecting in to have warped it's head, so it will be interesting if I have the same issues., whilst it's in bit's I may well forge the bottom end and shim the block from added security, not that many people crack 2.3 liners, but better safe than sorry whilst I'm in there, future proofing I think they call it, as she is always receiving olives cast of upgrades...:blowingup

[JT]

Managed to get some time in the garage today, so took a couple of example vids

one with a stuck cam (BTs old engine):


https://youtu.be/Agy3iA9vMME

[JT]

And one of my others:


https://youtu.be/SJwyY1V7IME

really surprising the difference, but something must be wrong somewhere

[MoleT-5R]

It's odd that on the one that the inlet is stuck on, you'd imagine both to stick if the warped head theory has anything to do with it.

As for garage time, to cold for me and I have to sort the place out fully before starting or continuing any project at present

it is a bit weird, on one of my heads, its the exhaust that is stuck????

it is cold out there, that why I have heating in my garage! but its sounds like we both need a tidy up ;)

[Blackdog]

Are they completely dry ie no lubrication? If so could it be as simple as a gum type residue binding things up?
Just trying to go back to the start to find root cause. Not trying to insult or upset.

Sorry re-read from the start of the problem.

So at what point of tightening the covers do they lock up?

Might be worth doing a progressive tighten to see where it happens. Is the cam then hitting the cover? Or is the tightening causing an unwanted load somewhere?

I cleaned the points of contact before installing the the cams, putting a small amount of fresh oil on the contact points, so they are not dry
and all seems well. place the cam cover on and push it down, then some cams become tight.
I say some, as we are talking 4 different heads.
Tighten up the bolts only seems make things worse

are the cams hitting the cover? what makes you say that?
that had crossed my mind, why they would I don't know, but interested in your thoughts

I know there is a specific way to torque the head bolts, is there one for the cam cover?

[Blackdog]

Just thinking that the clearance between cover and cams might be very tight. Hence suggesting that maybe you could try progressively tighten one of the offending one and see at what point it licks up. You maybe able to hear if it starts to knock on the cover.

[JT]

Just a small update

Having spoken to a few people/engineers, it would appear that the heads are twisted. doh!

Apparently they can be machined, but it doesn't sound like a cheap operation.

So I'll carry on with the 1 good one I do have, so after being surfaced, started to build it up again

19T with 11 blade billet wheel

I'm assuming the 11 blade billet wheel has an edge over a 6+6 billet wheel, just asking as I'm currently thinking of building up a billet 19T from the stock of donors I have here.

[oblark]

I'm assuming the 11 blade billet wheel has an edge over a 6+6 billet wheel, just asking as I'm currently thinking of building up a billet 19T from the stock of donors I have here.

From my understanding is the 6+6 billet wheel makes its boost lower down the rev range compared to the 11 blade billet wheel makes it boost higher up the rev range.

I'm running a 6+6 billet wheel in my K24 and I easier have a bar of boost at 3000rpm :)

well yes it runs, but its not right.

Afrs all over the place, smoking, checked and swapped everything possible and its still not happy.
Last weekend, I even removed the entire fuel system and cleaned it all through, amazing how much sh** came out of it, but its not changed anything.

Just flashed the Turbo Tuner with a different map and nothing changed???
Starting to think maybe the ecu is the problem, again...........
Swapped it for a standard ECU and the car wont even start! lol

Would by any chance someone have a TT lying around that works that I could borrow to eliminate this potential fault?
Or someone local enough (sussex) that knows how to work a TT, maybe take a look?

Supposed to be ontrack next month, so running out of ideas as to what it could be......

Not sure I want to put it on the rollers if there is an underlying problem

Cheers for any help

I'd throw the Turbo tuner ecu in the bin and go for M4.4 with an ostrich, alot easier to tune :)

Get my car running and you can have it :lol:

When I was at Abingdon in Sept, it wasn't right then either.
Same symptoms as now, hesitant on throttle, then all of a sudden it would kick in and take off! lol
Obviously sat in the garage is not the same comparison, but its still hesitant when throttle is applied.

I'm starting to think the Ecu might be at fault as believe it or not, its been sat on the shelf for 7 years,
Maybe the battery has died??

Yesterday, I put in a standard Ecu and the car won't even fire, forget running.
so I tried to flash the TT with the 'standard' map it comes with, car behaved exactly the same as before, like the map was not excepted.
Tried some other maps with the same results, from 2 different laptops.

Air leak on the boost hoses or a maf issue possibly, but then I'm sure you've already tried swapping the maf

[JT]

Air system..........

not the first to mention it, but i have checked the hoses, doesn't mean the IC wasn't damaged in the accident,
something else to check.

also, have now disconnected the PAS stuff, I thought it would effect the air a little, any thoughts on that?

on our v70r we had rough running and hesitant to rev up, but would go after a struggle to get the revs up, turned out a hose clip had rotted away and the IC bottom hose had blown back a bit, air leak was enough to confuse ecu and maf, maf was seeing higher airflow so ecu dumped more fuel than required.

not sure how PAS (power steering) alters airflow..? or I am being thick on interpretation..?

I’ll check all the boost pipes, again

Might have my abbreviation wrong there with PAS
I meant the VAC line to the brake servo, but have since learn’t that
should not effect it until brakes are applied

Come on, you mean you haven't pressure tested the system?

It's easy enough to make up a tester to bung in after the MAF, then just listen. You can even do it using your mouth, won't need much to find a leak

You can take the case off the ostrich and change the battery, it's only a cr2032

yea that looks a bit more professional.

Took mine apart and its not a simple battery swap. the battery has brackets attached, so I will need to invest in a new one.
but, as I had gone to the effort to remove it from the PCB, I checked it and it was still showing 3V.
So my thinking at this point was, the ecu should have lost its memory, capacitors aside, so I reinstalled it and flashed it.
Car started and first impressions were good, but no, same results. getting better, but the same.
If I alter the fuelling it doesn't change a thing, car runs regardless.
While I was out there and the car was warm, I changed the MSD coil.
Again, better but still not right. still getting white smoke

slowly but surely, getting there, but this ecu is starting to look like the culprit

The loom and ECU are both from my old 94 car

[JT]

so we did a thing last night ..............

33085

Found 1 clamp that was loose and a leak from the boost controller, but we think that was because it was pressurised as appose to a vacuum.
Either way, would it up to its max and that stopped it. Good little test that, cheers Dave.

For some strange reason, the TT has started to recognise different maps now too, so fingers crossed, removing the battery, did actually help?

Car has now stopped smoking on idle, but still does after applying the throttle. Just think it needs a good run now
We'll find out on the 14th, fingers crossed

Hi all

I have found a company willing to produce heated windscreens for an 850, (not sure if the V70 is the same?)

They would be approximately £300 each, but I need at least 5 to be made, before they would consider it.
I'm happy to have 2, and 1 more is already spoken for.

Would anyone else be interested???

I have asked a few questions, is it the whole unit? a kit we add? etc etc
Well aware these screens rarely come out in 1 piece, so to send one off to be modified, is not an option.
So hoping its all in glass and element for £300. I'll confirm when i find out more.

Clutch, need to upgrade now, currently running 850R clutch, but now with the gripper in, it cant cope anymore.

Thought I could hear it slipping.

[JT]

Similar spec to before, so in theory, similar power
But it’s not been on the rollers, so don't really know

What I do know is it’s over boosting, even with the MBC at minimum still heading towards 1.6 bar, not good on standard rods

Hi all,

thinking of selling my Team Dynamics wheels, to get some with a different offset, so I can run a wider tyre

would anyone be interested in buying my existing sets?
1 set is brand new with brand new Toyo R888, never been on the car
And the other set, as seen in the last post, have only seen 2 track days and have a used set of Toyo R888s on

just checking my options at this moment in time

JT

[Moonpiemagic]

potentially interested, what are the size of the alloys and tires. Wondering if they will fit my P1 S40 T5 and looking for a 2nd set of alloys specifically for track.

[JT]

Standard Volvo fitment, IIRC?

ProRace1.2 Anthr 7.5x17 e43 5X108-65.1

215/45/17 Toyos

[Moonpiemagic]

Ah pants, I cant fit anything less than 18" sadly

[JT]

Have you got some monster brakes on there then?

[Moonpiemagic]

Have you got some monster brakes on there then?

yes, just had some Ksport 8 pots fitted. They only just fit under the 18s which has changed my plans as I was looking at getting some 17" alloys for track and keeping the 18s for road.

[JT]

8 pots?
Must be like running into a brick wall :uglyhamme

HELP!!!

Car won’t start :(

I have no voltage coming from the ecu to the fuel pump relay.

Car was fine in November on its last trackday, haven’t touched it since.
Went to start it yesterday and noticed the pumps not priming

Tried with my TT and a standard ECU

Any ideas??

Took me ages to find it on olive when I first had her, when Gul let me down it didn't take long to find it and fix it, RAC man was well impressed how much more I knew about the 850 than he did, he pulled me from a busy spot to somewhere quieter and I fiddled with the wires and off she went again. Got me home from South Wales and then did a proper fix on her.

[JT]

Well swapped out the grey relay attached to the rad from a working car
And it still won’t pull in the fuel pump relay

Guess I’m gonna have to go deeper :(

[Dangerous Dave]

Bad immobiliser? Not sure if it cuts the fuel pump relay or spark though

You say there's no voltage actually coming from the ecu?

It's looking that way, make sure the wires to them are ok as they tend to break up and corrode over the years, don't know why I'm telling you that, with your line of work ...lol

[JT]

Nothing on the grey/yellow cable from the ecu :(

Didn’t think the TT used an immobiliser? Never had this problem before?

Maybe check the ecu socket to see if there are any issues.

Then test power and grounds to the ecu.

Here is a signal description list of what the pins should be with ignition on and when idling
https://www.matthewsvolvosite.com/forums/download/file.php?id=12185

[JT]

cheers Dave, I will study that later.

thoughts on this:

If I put an IGN feed to the fuel pump, the car will start and run.
can I just do that? anyone see any issues with that set up?

obviously would need to start the car once the IGN is switched on, so the fuel pumps are not left running for too long without the engine running

[Dangerous Dave]

Can't see it being an issue. Have it on a switch on the dash labelled up.

Well the separate switch works, which is good

Just something in the back of my mind saying is wrong lol

Oh the fuel pump relay somehow has water damage, even though it’s inside the car
Maybe that’s taken out something in the ecu?? Food for thought

[Dangerous Dave]

You said you'd tried 2 ecu's unless it fried both of them?

Guessing it maybe shorted and sent high current through the ecu.

One way to test it is to try those ecus in another Volvo...

Well that's good news, Not that I've ever tried an man ecu in an auto, but my understanding was that auto ecu's work in manuals and auto's (and that is true as both my factory manual T-5R's are currently running auto ecu's), but manual ecu's only work in manuals, but as above I've never tried them. I still think there must be a break/corrosion in one of the harness leads or possibly a faulty earth, but hey it's running so that's the main thing, whens your first track outing then JT...???

[Dangerous Dave]

At least you know now the ecus aren't at fault.

Interesting one, as Moley says, must be a bad wire somewhere.

First outing was back in sept at Abingdon, which was different,
and then a day Brands in Nov.
Hoping to get back there in May..........

[Moonpiemagic]

There are couple of track days added to the calendar at Goodwood for this month and may, if you are looking.

Would be cool to see these flying around the goodwood track, im just down the road from there.

I would love to do Goodwood one day, but as we don't race there, kind of seems a bit odd to test there.
Maybe in the future, if everything falls into place

[JT]

So far I have booked May 10th at Brands for a trackday
and pencilled in August 6th at Brands for my one and only race weekend this year, fingers crossed.

Will try and get another trackday in July if I can

[JT]

well not a bad day, annoyed another GT3 owner :biggrin:

What? you can't leave us with info like that. What happened?

[JT]

What? you can't leave us with info like that. What happened?

Well……….

Had a small leak from the remote reservoirs, so stripped it all down
and ended up replacing one of them, the bleed the whole system, in
preparation for the track day. But once at the track I realised I had no brakes!
Had to do the sighting laps with no brakes.

Made it back to the garage and bled all the system again and got the pedal back.

The engine has been letting by on the rings, so a bit of crankcase pressure.
So oil was finding its way out. So we just kept cleaning it up until lunch, when I then removed
The pcv which seemed to be in the middle of it. The small hose at the bottom, was to blame,
So swapped it out and all seemed well for a while.

It lasted till 5 minutes before the end, so happy we got a full days running.

Now to strip the engine down and rebuild with new parts including s60 crank, forged rods, forged pistons
and all new bearings etc

not really, but I'm going to run out of time to finish and test it before August :uglyhamme

this engine was built using all sorts of bits and bobs, just to get some seat time, so its served its purpose.

Well............it was Tuesday, yes the hottest day on record and I had booked a track day :lol:

Going back a bit, I said we had some engine issues right at the end of the last test, I think we found the problem!

33193

So new (ish) piston fitted and new rings while we had it apart and booked another test.

I was so pleased my mate turned up with his massive gazebo to keep us in the shade

33194

So yes a very hot day as I'm sure you are all aware, but with in car temps hitting 45 degrees and wearing the full fireproofs, it was a tough day
not just for me but the car as well.

Twice it overheated

https://youtube.com/shorts/Bl4gfsSRoPU?feature=share

But I did get some laps in. Not pushing too hard as I did not want to destroy the new engine components.
On a positive, no oil leaks!! Happy days !!

The new drive shafts survived the day, so happy with those
Anyone recommend some decent brake pads to suit AP CP5200 cailpers? currently on DS3000, but I'm not feeling the bite

That would probably explain that then, was that the fan itself or a fault with the electrical supply...?? you could do with something on the dash to tell you that it is operating when your racing, just an idea..

[JT]

so after investigation

the fan works
the relay works
the sensor works
all cabling is good
and if you unplug the sensor the fan will run in a failsafe mode

but if i warm the car up, it still wont run the fan??

So, the fuel pump stopped working a little while back
now the Fan

I think my ECU is slowly dying :rolling_e

The ostrich will fit into the 4.4 no problem.

Ditch that 4.3 and TT and run the modified 608 map from Volvospeed then you can datalog superfast

[JT]

Need to do something to bring it a bit more up to date

good news, fan has decided to start working again
bad news, it appears the overheating has cooked the valve seals, so its developed a really bad smoking habit.

no racing for me:wallbash:

[MoleT-5R]

Sorry to hear the racing is off, but Happy Birthday mate, hope you have a great day:partysmil

[JT]

Suspected head gadget failure, probably due to the extreme heat at the track
and lack of air through the new bumper

I’ll keep trying, not going to give up

[Dangerous Dave]

Oh no, after all that too :(

[MoleT-5R]

J.T. are you still running a stand rad or have you upgraded the rad, if not it may be time to.......also is the water pump ok and circulating effectively... just a couple of my thoughts as the grill aperture is quite a size on an 850 and would have though it would allow sufficient cooling even out on track at your power level.

[JT]

The standard rad gave up very early on, like 10 years ago
water pump was ok when fitted, doesn't mean its still ok

I run an alloy rad now.

Nice rad J.T......I did recently hear of someone having over heating issues which was baffling them, when the water pump was removed it was found to have stripped it's self of it's impellor blades.

[JT]

Thanks

I've seen the aftermarket ones do that, but not an OEM part.
When I get around to stripping it down, I'll check it :)

[MoleT-5R]

What do you do thermostat wise.....?....not run one......run a standard one or run one that is drilled to allow extra flow??

[JT]

There is just a standard one in there at the moment
I used to run without, not sure it made any difference
But I’ve never had overheating issues before

Well. some of you may already know but, went for a play at Brands Hatch on Saturday.

It was slippery as first thing in the morning, but dried up quite nicely, so got some good running in.

Nealevo came along for the banter and was brave enough to get in the car too, if only to do his nails! lol

Developed a small oil leak in the afternoon, which meant an early bath, but it was getting late anyway.

Overall, a very good day out :B_thumb:
