What causes a lifter noise in an engine?
Lifter noise is caused by the valve train components “lashing” back and forth. Older engines require periodically setting the lash to specifications. New cars use hydraulic components to cushion the lash.
What makes a lifter tick on an overhead cam engine?
A lifter tick is caused when the push rod or camshaft doesn’t make continuous contact with the lifters. This can be because the lifter has become worn out, as is the case usually with hydraulic lifters, or the valve has come out of adjustment. Which can be the case with overhead cam engines or engines with sold lifters.
Why does an overhead cam engine make a clicking noise?
In an overhead cam engine, the camshaft lobes themselves depresses the valve while in single cam engines, the cam actuates push rods that open the valves by moving a lever called the rocker arm. Since your valves move very quickly and only move a short distance, the distance from the cam or pushrod to the valve needs to be very precise.
Can a bad lifter cause a car to tick?
A bad or faulty lifter in the engine can cause the lifter tick and this has to be pulled out and rebored, which is not a job for the laymen. The best method for dealing with this form of tick is to take the offending vehicle to a garage and have the professionals place a diagnostic tool onto the engine.
When does a noisy lifter start the engine?

What should I do if my valve lifter is making noise?

This is probably the best solution to avoid noise from lifters.
Why does my lifter make a ticking noise?
If the suitable oil for the appropriate engine is not provided, then the oil will end up being too heavy or too light for the engine. This kind of improper lubrication will result in the buildup of dirt and sludge which will prevent the proper functioning of the engine by making metals come in contact to cause the tapping and ticking noise.
