Excaliber..........You are correct on almost everything. Long periods of idle. Lots of stop lights. Idle speed way too low. My ignorance ...........That was the first time on the cam. The lash was set and checked per the cam card several times. The heads were built up after cnc port job with springs to match the cam. When the lifter failed it damaged 1 lobe slightly and 1 other lobe was scored a little. The cam builder was confident that it would be a simple fix at a fraction of the price of a new cam. Funny thing is the 2 lobes that were repaired were not damaged on this last failure. I plan on a complete tear down and dunk the block. I replaced the main and rod bearings including the
oil pump on the first go around.
Thanks everyone on their input. When it is said and done my valvetrain will be all new and hoppefully BULLET PROOF. Berm
