Audi S4 oil consumption
Discussion
I have had a problem with mine using alot of oil(2005 4.2 S4). It was smoking from cold start so put it down to valve stem oil seals. Whilst the engine was apart we replaced the VSOS and every thing else looked perfect, even compression was exactly the same on every single cylinder. As a precaution we also had the PCV valve replaced which controls pressure in the crank case? It doesn't smoke an ounce now meaning we fixed the problem and runs perfectly still, but does seem to use alot of oil still. From reading the other posts it seems it might just be the way it is? But if you have any cleaver ides It would be much appreciated!
