Fired up my one generator as where getting near the power loss time here in Michigan. After it ran a while if spit a quantity of oil out of the tube that fits into the valve breather cover. Stopped it and let it sit awhile. Would estimate it spit about two ounces or so of oil. After it sat awhile I started it again and it ran fine, no more spitting. Any idea of what might have caused this or what I should look for or check out?

Thanks..
Bill

A few things to check, make sure it is not overful of oil. Is it an overhead valve engine? If so, make sure the drain holes in the head are open to allow oil to the valve train to drain back to the crankcase. Also make sure the crankcase ventilation system is all connected. If it has a pvc valve make sure it isn't plugged. The crankcase has to breathe, or it'll push oil out somewhere, valve covers and main seals if it can't get out the breather. If it stopped, I don't think you have a major problem, serious problems only get worse, they seldom go away for a time. John in Nebr.

Had this problem on a truck of mine once. Thing was, I had the valve covers plugged off so there was no pcv valve or valve cover breather. The engine built up pressure and started to spit out oil through the top of the dip stick tube. I know, I know, it's stupid of me, I was young and dumb, but I learned from it. It stopped as soon as I punched the holes in those chrome valve covers and installed the breather. I'm not much on small engines, but it could be just a case of over-filling, but I'm not sure. I just thought I would share my experience.
