Hi everyone and happy New Year. I am about to remove the head on my '54 A10 to replace the gasket to stop my last oil leak, but at the same time I want to deal with a top end rattle that I thought was an over-big valve clearance, but isn't.
This noise according to my listening stick is definitely at the top, on the left side only, and increases intensity when I rev, then fades away when I back off the throttle, but reappears when the revs settle down. Is that what piston slap sounds like?
