just a bit of suitable shim and some araldite or smiliar... simples

Lol, I certainly wouldn't use araldite, no you need to use JB Weld of the right grade that can withstand the heat.

this one??

**claymore** · Sunday 28th July 2013, 09:07

yep, that would do. I've got plenty if and when you need it.

Saturday - I picked up my old engine which had been sitting out the back of HLM. I'd already had the sump off it due to a sump plug weep issue.

Had just a few hours spare today so I got both oil pumps off. I had a mare with one of the hex bolts holding the 2 halves together. In the end I had to cut a slot it in with a dremel grinding wheel & use an impact driver & a hammer to get it to budge. Really annoying when you have limited time. Anyway - I got to use the cleaning bath my wife bought me in 2011. Both have the metal caps as previously discussed - so I am not sure which I should use?

I've sort of got to a point where I am unsure how much more to do I need to remove the crank out of my old engine - if I do take the crank out of my dead new engine - what do I look for in the big end shells? Would now be the best time to throw the hole thing to an engineering firm/engine builder - so they can diagnose the faults?

Should I use my big red tank to clean the block up? Any cleaning tips would be appreciated.

Yes IMHO. You've probably learnt a lot in the process and I certainly admire your efforts this far. My 850 is sat on the drive way with a blown engine, no way I'm even going to attempt it, but I know a man who is at the top of his game and once I've saved my pennies it will be straight to him on a trailer.

If your old Engine was working fine??? then I would use that! but only if it had no known problems?
My T5 Engine came from an Auto T5 (so not had a hard life) as the other one had a rod go through the block, the serial numbers where taken from the crank to get the correct size shells, there was a 1000th of an inch skimmed of the liners and OS1 pistons fitted, China rods fitted, the head was ported and flowed, even the intake and outtake right through to the zorst, new valves re-ground and fitted, TTV fly wheel fitted VXR injectors and it's been fine ever since! touch wood!

I firmly believe you are throwing money away by keep going to engineering firms asking them to do this and that and commissioning them? As all businesses will take a persons money, You need to find one person not a firm, I am sure there are a few builders on here who could do a build all day long! rather than a Engineering firm or builder or you are going to spend a small fortune again, the recipe for a solid engine build with all sorts of power & turbo's has been posted time and time again over on T5D5 and they are still going strong today!

I think you should have a good read over on T5D5 and ask questions here and there before you part with anymore of your hard earned money and then make a discussion, as no one wants to see thing go wrong for you again Dave!

Cheers Greg

The old engine was using water & had shown that the H/G was on it's way (confirmed on a sniffer test). That doesn't matter so much to me.

My RCA is going nowhere - I am no closer to the truth about where the oil went. Turbo has a clean bill of health. The 2 oil pumps look identical & I still don't know if pushing on with ME7 will even work.

Sorry, RCA? What are your doubts about ME7?

**Wobbly Dave** · Monday 29th July 2013, 13:17

I am under some pressure to get the job finished by her indoors & then not touch it again for a long time. I can't give her any assurances. Perhaps the whole notion of pushing the 2319 this hard is flawed?

Root cause analysis - something I have to deal with a lot in IT problem solving.

Doubts about the ME7 in terms of throttle response. I have to ask it & if the ECU on closed loop says it's not going there it can override me - at least that's what I think it does, which is not condusive to a decent 1/4.

could this problem be programmed around ?, by the right person, obivously above my level at present

**Wobbly Dave** · Monday 29th July 2013, 13:41

The whole purpose of the on-demand throttle is to make it smoother because the engine can control the phased cam timing, which if I understand it correctly alters the relative position of the exhaust cam.

Only way to program around it would be to go simpler. Delete the VVT cam & use a vernier pulley (which in itself is a compromise) and return to a manual cable throttle.

Simply means buying 850 which I'm not sure I want or preferably a 1998 C70 which are virtually impossible to find. The auto is not a problem because the gearbox swap would have to happen.

That's a lot of headaches & Wife-based grief just to set a time?

Other option is - I cut my losses now - sell up and move onto something else.

dont quit dave. even if you had to bolt the subframe back on and get itback on its wheels and park up in the corner for a few months. if it was me in your position id be doing on of two things. it either be buying a engine stand and doing the work my self as and when feel like it. or bite the bullet and ask tim willams if hed be willing to rebuild and fit engine. with out doubt hes one of the most trusted people inthe world of volvos and he knolodge and experience will help you like no other can. youve gone to far to quit now.

**V70 Graham** · Monday 29th July 2013, 14:05

I can imagine how you feel Dave, maybe just speak to Tim (and a few others) and pick his brains on which way to head, I'm sure he'd give you 15 mins of his time.

**Wobbly Dave** · Monday 29th July 2013, 14:18

Already have an engine stand, I don't have the precision engineering tools or experience to make this work.

I am more uncertain about the ME7 as a design - just like no-one would run a standard geartronic g/b to go down the drag strip either.

I was meaning to re-program the ecu to get around the bits you don't like and keeping what you do, as there appears to be knowledgeable people out there who are able to re-program the ME7 ecu, thus you don't need 850 throttlebodies and cables, pedal, harness etc

**jardon** · Monday 29th July 2013, 14:47

John (Dream3R) has been doing some ME7 programming. I don't know why you're worrying about vvt - it might make a 5% difference to the finished performance. Ignore the vvt. You just need control of throttle opening, fuelling, boost and spark advance. The "point" of ME7 is emissions control and engine protection.

befor you get to far into the build again id be speaking to the likes of shark performance and see what they say about mapping this kind of management. ask as many question to as many people who have the proven knolodge of these systems and builds. i know nowt about ME7 so thats about the only advise i can offer.
