You can take a look at least on drivers side.....might see clear evidence of pad wear, it's the bottom that you can not see unless you remove the thing. How many miles on the car?

90k, just barely.

Unless there is some other cause of the problem, I am not sure what else it could be, then you don't have much choice. You would be replacing the Cam Chains also, and the 52 bolts as well as the seals.

thanks, I think. BTW, mid atlantic audi has the tensioners at 653.

Mike do you have the part numbers for this stuff. Tried to PM you but box is full.

Sorry, did not know my inbox was so full explains why I never get a new messages.

Camshaft Tensioners

ECS site:

Bank 1 to 4 077109088P $685.91
Bank 5 to 8 077109087P $685.91

aftermarket ones are $374.00 I could not verify if these are made by the same manufacture as the Audi part. Most of the time they would be listed as "OEM supplier" implying made at the same place. I cannot image that the 'aftermarket' ones are made by some other company since tooling up to make a limited use product like that would be CRAZY. But I did not want to risk it. Both had same warrantee.

I went with Audi parts right from Audi dealer, paid $720 if I recall...The cam tensioners and bolts came in 1 day from supply house in New Jersey. No idea of the supply available. That part is common to all the Audi 4.2 V8's since 1999. Last Revision "P" was 1/1/2007.

Cam Chains at ECS:
Audi part: 058109229B $142.91
Aftermarket: $29.95...yikes..why the difference? Audi ones are Special?...

I got them from pelican, same price, went OEM manufacture without Audi name.

Kit with all the seals including valve cover gaskets.
Blauparts.com site: Pretty nice kit and a good price.

$139, on sale. LOL I paid $149.

The Bolts, don't forget the Magic 52 bolts! I got them from Audi $60 or so. Local VW dealer had 10 in stock and wanted $2.50 each.

Runs about 15 or so hours of labor if not screwing around. The passenger side requires carefully moving the coolant pipe since it is in the way of getting the valve cover off.

Of course consider timing belt service if due and a new serpentine belt and idlers, "since your there."

Logged during drive, for some reason couldn't figure put how to save it. I didn't see much change from my numbers above. Pretty consistent at idle 0 - 5, both banks, under load as high as 21.5, both sides, the negative 7 and 9 persist in block 93. So park it, buy the good tensioners, prepare for wallet draining?

Your car should be running like complete crap yes? If not, maybe it's not the cam tensioner pads. Remember, you can just replace pads for $30 parts. My car basically wouldn't drive with failed pads. You're getting the flashing CEL right? Maybe some other electrical issue to the plugs causing misfires?

[EINHORN]

1st, thanks Mike.
lswing:

No. Car is running great. Noticed slight misfire when cold started after a four day rest. NO flashing CEL, just on. Will clear, and stay off for a couple of days. Then slight misfire that clears quickly. Seems to get better gas mileage with new plugs and coilpacks.

trying to figure whether I can continue to drive it. TT going in for fender paint and some odds and ends.
