Right on the money, Carl- - - - -if a pushrod isn't spinning as the engine runs, it should definitely be checked to see if it's bent. An engine doesn't have to be running to check for lifter rotation. Simply spinning the crankshaft with the starter with the spark plugs removed will generate enough spin on the lifters to see them, and the pushrods turn. I check for bent pushrods by rolling them on a piece plate glass, cut to be a little shorter than the overall length to let the bulged ends hang off the edges.
