Bad oil leak!
 

My car is loosing a quart of oil in 500miles. This is really bad. The whole oil pan is dripping oil, it spreads on the cats and everywhere so when I park I can see smoke coming from under the car (burning oil) it also smokes under the hood on passengers side mostly.
I did replaced valve cover gaskets and front engine seals. Thought it was the oil pan, took it off and resealed it with some RTV sealant and old gasket. Did not help, purchased new gasket and installed it with RTV - still no use. Can not say if it's worth or not.
If it's not the pan leaking it must be top pan section. But could it really leak so much? Oil level is lower than that connection.. May be it's still the bottom pan? Is that possible?
I've researched on the board, is there any chance that my pressure is too high inside and oil is being pooshed out? There must be some breather valve behind the engine, how can I check if that's the case? May be I should disconnect breather hoses and see if it helps? =)

Also, top pan section on my model does not have a gasket, is it better to use just silicone?

ps/ its not the oil plug or anything simple like that.

Thanks.

Just to get things clear, tell me what engine do you have?

Sorry, I thought A6 came with only one engine, it's 2.8 30v AHA

Could be your cam adjuster seals, in combination with a clog in the PCV system somewhere. Those seals can leak a lot of oil if pressurized.

You mean cam tentioner seals? No, not those... Well they are leaking but not that bad. The major lkeak is on the bottom.
