Hi. I am new to the board. I was wondering if anyone knows how to replace the crankcase breather filter on a 1994 Audi 90s? I am getting blue smoke out the exhaust when the car is hot and I think the filter is the cause of the problem. Problem is I do not know where the filter is located in the engine to repair myself, and do not want to spend the money to have my Audi dealer do it, since I live in Brooklyn, NY and I have yet to find a good audi dealer mechanic. I.e. I brought the car into the dealer because I was losing power going uphill and they charged me $170.00 to tell me they couldnt find anything wrong with the car...
any help is much appreciated,
james

 

does it have one I wonder im sure its just a breather pipe, do a compression test because it sound like valve seals or worn rings

 

Yeah could be. My brother is borrowing the compression tester .

before you go ripping the cylinder heads off you can get an oil additive which re-vitalises the engine oil seals if the blue smoke is minor ask any aftermarket place ( STP )

 

I'm sure audi doesnt have one too, only fire preventing device from backfire into intake manifold, they dont want oil to catch on fire, do they.

 

I think my reply did not post, if it is a repost, my appologies.

The additive will not make the problem worse if it is the breather filter? Also where is the breather pipe? Maybe I can disconnect and
take a look to see if it is clogged or restricted with buildup of oil.

thanks,
james

 

they are located at the end of the each valve cover. there is a tube about 15mm diameter, that goes from the cover to the throtle plate.

 

Thanks man. Will check.
