Possible valve cover gasket.

Leaking onto the exhaust? Sounds like a seal to me. Rear main would make sense but I don't think it's that big of an issue. Is yours leaking?

leaks happen. every type of car can get them. just find the source of the leak and fix it.

I have an 2001 Audi 2.7T. It has been leaking oil. I had the oil gasket replaced/fixed 2 months ago. The car was working fine but then the check oil light came on after driving for 3 weeks. The folks at the garage told me that turbo's eat up gas. They filled up the oil pan and asked me to bring the car back after 2 weeks - I noticed that that there was fresh oil drips on my garage floor. I did and the oil was low. The garage did some looking around and told me that there is an internal and external leak in the Right turbo and the oil was dripping on the catalytic converter. Their recommendation is to replace both turbos. The cost is $6000. If I don't replace the turbo, then the converter maybe drenched with oil which will kill the converter. My question to you all is: Is it an issue? if so how big of an issue? Can I drive the car and for how long? Is the cost quoted reasonable? I also need to have the oxygen sensors and the exhaust gas temp sensor replaced. The secondary air kombi valve bank had showed up last time sensor were checked but not this time. The total cost is close to $8000 to fix. Is it worth spending the money or should I get a new car?

more like rocker cover gaskets they leak on to exhaust.

Faulty by design.

Here is the answer you need! It is not just exhaust, it is all over the engine. I've dropped 3K into fixing these problems by various sources available. Amateurs to Pros. FYI - it will come back in 2 years for ya. Faulty by design is the final conclusion! I'm planning to keep the car. Radical fixing only, at this point. Replace with a different engine, or mod their engineering. Fun fact: replaced "donut" cam seals but they still leak? Why? Cause the old ones have worn groves into the metal of the cam! Look close if you are at it. You got to swap the cam. YeAH!
