|JCrutt said: (quoted from post at 15:48:44 12/02/12) My 1950 JD B Poof"s out smoke by the clutch and blows valve cover gasket out at the same time. All vents have been removed and cleaned, it"s getting very annoying. Run"s great. Looking for idea"s. Ventilator pump issue?|
Sorry, I got interrupted, so I'll edit my typos now...
Could be that the vent pump is not working properly, and that is allowing fuel vapors to collect in the crankcase, and a poof that is strong enough to blow the valve cover gasket out of position is actually an explosion.
Take the oil fill cap off and lay a playing card over the pipe. If it sucks down a bit, the pump is working. Keep your face away in case she poofs while you are testing. This post was edited by F-I-T at 19:11:58 12/02/12.
