Hi, I am trying to get a 1946 Chevy pickup I just purchased running. The motor turns freely, but when I popped off the valve cover I noticed one of the push rod's was missing. Needless to say, I ordered a new one, but upon placing it into position and turning the engine over by hand, the stuck valve did not want to give!
I have read all over to put Marvel Mystery Oil on the valve and tap the top with a hammer. Not sure if I should be hitting the top with a lot of force or gently tapping (so far it has been gentle) I still have not been able to break it free. The last time the truck ran was in 1956! Should I drop the oil that is in there? There appears to be lots of sludge, in the upper part of the motor. I also put my finger to plug the spark plug holes, all but the cylinder with the stuck value blew out any air, I am not sure if this would be correct. Also, I assume if the Intake valve is moving on that cylinder the piston should still be good?
The cylinder is the one closest to the water pump.
Should I remove the head? I am trying not to, as it appears to be a lot more work.
Any other ideas or thoughts would be greatly appreciated.
Thanks in Advance, Chris
