mpnye - Mine were warped longitutially from front right to left rear. The long sides were flat and if only one side of the cover was put on the edge of the flat surface it was flat. When I say warped I guess it would be more accurate to say Twisted slightly. As mptje says - no leakage along the flats - only in rear corners. The diagnoses was done by Mercedes Dealership. Found it hard to believe but apparently it is not that uncommon. Until I put the cover on a flat surface and saw the warpage (twistage) myself, I was skeptical. When it came back from the machine shop - all wobble was gone and the cover no longer weeps in the back corner. According to the machine shop - who specializes in racing cars - it is very common for cast aluminum valve covers on racing engines to warp also if over torqued.
