22k miles, dropped a hydraulic lifter in #4 cylinder exhaust. Lifter bearing broken in pieces and spider retainer also broken and fell into
oil pan. 1 Camshaft lobe trashed. So there's a lot of metal part in there. Did a leak down and compression test prior and they were good.
Does the motor needs a refresh or complete tear down to see if any other parts are damage? Motor is already 85% apart in car right now.
