Hey guys, I have a 1958 Oliver 550 that is getting fuel in the crankcase. I had this problem last year and found the diaphragm in the lift pump was bad. I fixed that and all was good for a short period, but now it's happening again.
What's the chances my injection pump is the culprit?
When the weather breaks I plan on pulling the lift pump back and checking that again but I'm doubtful the new diaphragm is bad already.
