This has been a problem since I got my motor (on a GEBE system). I had leaks on my first 5 -10 miles Dennis from GEBE said it was due to too much oil so I drained some out. It ran pretty good for the next 80 or so miles but tonight after a short (2 mile) trip it was leaking again and smelled like burnt oil. Also there was oil coming out of the top spark plug cover. Any thoughts to help me out on this? I am thinking of draining a bit more oil but I do not want to go to low. I am using 10W40 grade oil, should I try SAE 30? any thoughts would help. Oh and I am driving it in Arizona which is 103 to 112 degrees lately.
