I own a 2001 Audi A4 2.8 Quattro. Recently I have smelled burning oil and took it to a mechanic to look through. He told me it was my "Timing Chain Tensioner Gasket" or "Cam Chain Tensioner Gasket" and then told me the cost to fix would be over $1500. But, then he asked if I wanted to change my timing BELT. I was under the impression you either have a chain or a belt, not both. Please help and let me know about this gasket and the correct estimate to fix. And does this vechile have a belt or chain??

Also I need to change my O2 sensor. I believe it is the front drivers side one (slot 2?). Where is there an online tutorial that shows how to change and which check engine code refers to which sensor? And where to buy?

And I need to change my CV axle boots. Tutorial? Where to buy?

Sorry for so many question, but I am new to the A4 and was told that this forum was the place to get questions answered.

Thanks for any help you may give,
-Ben

 

I think they need to remove the cam, so timing belt will have to come off anyway. The chain is on the back of the engine, t-belt on the front.

Was the price for doing both? Sounds a little high to me.

You can find a lot of write-ups on audiworld.com under their tech section.

The O2's should not be too hard, for the cv boot you just need to replace the whole axle shaft, its cheap just to replace that rather than trying to fix the boot, so I have heard.

 

Yup^^ .... and....

 

to elaborate that would be dry no KY

take it somewhere else or DIY
