""Has anyone had experience with Blow By in the Onan? I took our "New" coach out of storage today for the first time in about 4 months. The coach has had nothing done to it since we acquired it. I started the Onan for the first time and had a horrendous experience. The P.O., or someone had replaced the oil filler cap with one that did not have "wings" on it that would hold it in. The result was an oil geyser that covered the Onan, me, coach and part of the driveway. There was no shutting down the Onan engine with either the switch on the Onan or the remote switch on the interior. The unit sounded good and ran well until I pulled the plug wires to shut it down.
My question is: Is this amount of Blowby normal? The shut down switch in another problem that I will address when the engine dry's out.""

Hi Bruce--although I don't like it, it seems to be typical of these old Onans. Mine did it before and after I rebuilt it about 10 years ago. It runs perfectly and uses just a bit of oil while running 24/7 for days out here in AZ
