Just picked up a 1988 300E, runs great but in the coarse of 3 weeks the crankcase has filled up with fuel mixing in with the oil.....Drained the oil and approxiamtely 12 US Quarts came out!!!....What could possibly be causing the fuel to bleed into the crankcase.......When I got the car 3 weeks ago the oil level was normal!....Thanks in advance!
