Can a bad lifter damage the camshaft?

When a lifter goes bad, the inside section of these lifters can go all the way down to the point where they contact the camshaft. So, the roller on the lifter presses against the camshaft and can damage it to a point where your camshaft would need replacement in the next 10,000 to 15,000 miles.

Can noisy hydraulic lifters cause damage?

It can even cause very serious problems and damages to your car in the long run. The damage can be from fixing some components of your motor that are alone far more expensive than just fixing the lifters, to the total collapse of engine’s functioning.

Valve lifters are one of the first components to suffer wear when the oil pressure is consistently low. Low oil pressure can result from a number of factors, including excessive camshaft end play and worn cam bearings, worn oil pump gears, worn crankshaft journals and bearings and worn main and rod bearings.
