My sick S70

**Liddo** · Tuesday 17th January 2006, 19:07

Some of you have probably read my posts on my knackered engine. Well, I took it to an Engine Repair specialist tonight, and he doesnt seem to think its anything to do with the cam, as the last mechanic said. He thinks it sounds like its possibly a simple job (fingers crossed) but he's never heard anything like it before! He said its just possibly a loose sparkplug and ancillary, well I hope so.
I've attached a link to a video of the engine sounding crap incase someone else has had the same issue.

That does indeed sound a bit rough, hope its a cheap fix liddo and you dont have to end up selling things off to fund the repair.

Me too mate! After driving her for the 1st time in six weeks, I realised just how much I've missed her! I reckon the alloys may STILL have to go, but Id try and replace them with used Comets

ouch.....
having said that it sounds top endy possibly head related....

Have you tried the mechanics stethascope to locate it.....used this loads to locate probs when I was in the trade many years ago!!

Long screwdriver...stick the blunt end in your ear and poke the sharp end on the engine at strategic points..... surprising what you find with it....

Liddo good luck with her, try not to sell anything on her, as you will only regret it, rob or borrow not literally to get her back on the road but keep your mods mate,

Liddo mate, sorry your car is still sick, assuming your engine is on idle in the video (850rpm) then ask yourself is the knocking noise at half that that speed. The cams run at half engine speed, can you count 425 knocks a minute?

Sorry if this sounds patronising but the lack of response to your original query only indicates how hard it can be to diagnose engine noises, as you can no doubt confirm having taken your problem to various experts for advice.

My opinion? Take the offers and guidance given by the known forum members.

Having said that, I think it’s a cam or auxiliary pulley knock. If not, then feel free to shoot me down.

Regards

Engineer

Been there, done that

Its deffo in the head somewhere, but when the guy said it could be a loose spark plug, it made sense i suppose, but then, I'd of thought i'd of got a misfire! I'll be gutted if it is just a loose plug

Lots of ticks every second i'd say

, and it rises and falls with the rev's!

auxiliary pulley knock??? The belt was change 4k ago! The guy asked me that as soon as he heard it, and took the cambelt cover off, but he couldnt find anything obvious.

So it still sounds expensive

Hope you managed to get her sorted Liddo, I know there's nothing worse than engine trouble. I had to have the head gaskette done abour two years ago, should have cost me about £200, ended up needing a replacement head as well, the total bill was well over £600!.

If you need any help with anything let me know, I'm only in Wigan.

Cheers mate, thanks very much for the offer.

No probs, while I'm thinking about it there's supposed to be a really good Volvo garage(not a dealer) in Bryn(near Ashton) which isnt that far away from you. They're all ex dealer mechanics, if your interested let me know and I'll find out their number for you, they also have loan cars too I think.

Update:

The mechanic has had ALL the belts off, and couldnt replicate the noise.
Checked all the plugs etc etc
Took off the cam cover, and found all the hydrolic tappets to be fine!!!

He's going to take the sump off and have a look at the bottom end this afternoon.

He's completely puzzled and has never come across this before! Typical

Will keep ya posted
