What the F£CK!!!!

[Mark Halligan]

Nothing gay like a broken valve spring is it mate?? maybe one of the inner springs cracked and making a noise??

what sort of noise would that make?

[audiman]

clacking/tapping noise, but would do it all the time, not just on overrun or accel.

Maybe that the small spring has broken and the big spring is keeping the valve shut, so the compression is good, just a thought really mate as so far we/you havent found anything that was making this noise. I never heard the noise so i cant tell what it was like. Might be worth just pulling it apart to have a gander.

Nope just under load, I might have a look though just in case.

I started it with clutch depressed and the noise was still there when revved and when the clutch was down when running it still did it too, with no change in noise.

OK so thats that ruled out then. This is doing my head in. And its not even my problem!!!

Mark,

I guess you would have felt better if you had found a mechanical explanation of the noise i.e. everything mashed up! Thank the Audi Gods that wasn't the case.
I notice you said in an earlier post that the car sounded "like a diesel". As the typical noise of the diesel is an artefact of the combustion process then I still think what you heard was the uncontrolled combustion in cyls 1 & 5 due to the pistons. To add to the lexicon, people use "dieselling" as an expression for knock!
Let's hope it runs as sweet as a nut!

Tom,

this is what I was telling you about earlier today about the colour of the ceramic coating on the two pistons that had the Det damage. You can see that one and five are a lot darker......that coating definately got tested there!!

[caterpillar]

[caterpillar]

no vakuum leacage????it seeems so on the pistons nr 2,3,4. and it will nocking in the engine!!!!

The firing order of all 5 cylinder Audi engines is 1-2-4-5-3
