What oil additive quiets lifters?

Liqui Moly 20004Liqui Moly 20004 Hydraulic Lifter Additive is specifically formulated to prevent hydraulic tappet noise. It does this by cleaning the lubrication ducts and holes in the oil circuit. In doing so, it also optimizes the performance of the hydraulic tappet. What’s more, it increases the overall performance of the vehicle.

What can bad lifters cause?

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.

A: Not necessarily. If the carbon buildup is on the piston rings or ring grooves, it can prevent the rings from sealing properly, thus creating low compression. It’s worth trying to “de-carbonize” the engine with GM’s Top Engine Cleaner or SeaFoam Motor Treatment.

Will switching to synthetic oil cause lifter noise?
