Ive got a 2008 e70 X5 4.8i. Few weeks back I did the "alternator bracket" gasket. So today I started on the valve covers and front timing cover gaskets.Took the crank case vents off and had this lovely surprise.
Driver side
Passanger side
Does anyone have any ideas? Doing some research, Ive learned that this can be cause by moisture in the crank case.
Both rubber valves are crack free and still flexible. This being said, I don't know if these have ever been opened before or any work done on them.
The car has 95,000 mile and no records of valve covers of timing cover gaskets being done before. Bought the car at 88,000 miles.
Any and all insight will be appreciated.
