RE: IML: Lifter collapse - 1955

["Robin Giesbrecht" <robings@xxxxxxxxxxx>]

If it is just one it could be just a bad lifter. I would try a stethoscope 
to try and narrow it down as far as location. I would then pull that side 
valve cover off and check for proper lifter preload as well as possible 
incorrect valve stem height. You never know with an engine that has an 
unknown history. Just look for a valve stem that is sitting higher or lower 
than the rest. It happens whether from a bad seat or a wrong valve 
installed.
