Debris is the number one cause of roller lifter failure. Since they rely on oil flowing through tiny passages, pieces of debris can hurt lifter operation. Clogged passages can stop the lifter from pumping up and cause excessive noise. The increased play in the valve train hinders valve motion.
What causes the lifters in an engine to go bad?
Hydraulic lifters can collapse, with no oil cushion to dampen the pounding from the tappet or push rod. Solid lifters can wear on their camshaft side, along with the camshaft lobes. Too much oil in the crankcase can cause oil aeration, or air bubbles, a condition when the crankshaft churns up the oil by direct contact.
