Hi Guys,
I need some advice on my problem i have with my Audi A6 2.7T 2001.
I recently removed my engine and rebuilt my turbos. While the engine was out i decided to replace the rocker cover gaskets as they appeared to be leaking. i thoroughly checked the entire engine over for any other oil leaks and found none.
So now the engine is in with its new turbos and new gaskets....and the rocker covers start leaking again. they both leak and is apparent in both back corners of the covers and leaks onto the exhaust manifold.
I decided to do the job again and replace the gaskets. turns out the gaskets leak again in the same place.
To clarify....i first torqued the covers to 7 1/2 ft and second time around to 8 ft.
I am now lead to believe that the crank case must be pressurizing and think that this may have something to do with the big vacuum pump that sits above the engine at the back. Maybe this is not doing its job sufficiently ? or maybe there is something else to look at which is why i am asking you guys for your opinion.

Your feedback would be greatly appreciated.
