Hi, I just bought a 1980 750k and drove it home. I thought it was running a little off and attributed it to the carbs not being synced or jetted correctly. I went home and looked at the spark plugs and decided to take the valve cover off. I am just curious to know if oil build up like this is normal or are rings worn/old and leaking oil upwards. I'd appreciate any thoughts/advice. Thanks.
