tresi How many miles are on it and how many time have you change the oil? If the ring haven't seated yet the oil will turn black really quick. part of this blowby and part of it is the microscopic metal particles from the rings and cylinder walls.

oldschoolrods Is your engine running rich? Carbon will cause the oil to get dark.

onecoomofo Not its actually not leaking any oil at all, which isn't normal with me so I'm happy about that. Starts just fine. It runs great. Sounds great. Just dark oil. However, I'm no expert at looking at oil, this is the first motor i've built. What all causes the oil to get dark this quick?

dark oil?

I have a motor I just built, and for some reason the oil gets very dark/black about 100 miles after I change it. Is this normal or does it have something to do with the blowby on the rings getting into the oil? For some reason i don't think we lined up the rings correctly when we rebuilt it?
