Bearing noise is usually deeper and comes from farther down in the engine. Lifter noise is more of a ticking and is up in the engine heads.
Worn valve train parts due to high mileage, lack of maintenance, abuse or contaminated motor oil (coolant mixing with oil).
Tapping valves is a noise made by too much clearance between the valve lifter and the valve. Modern engines have hydraulic lifters. If you have too little oil pressure or run the engine low on oil, the lifters will make noise. The lifter can also wear out.
Collapsed hydraulic valve lifter? Rocker arm (valves) need adjusting?
Most probably a loose tappet. Check the valve clearances. Or a valve could be sticking in its guide.If the lifters are hydraulic (unlikely on older cars) they might be gummed up. A good flushing oil will clear sticking valve and lifter problems.
Depending on the vehicle, it most likely needs adjustment.
It depends on what's tapping. You may have a bad lifter or a valve problem.
There's a ticking noise under my 2002 tahoe. If it is a lifter. Can you tell me what a lifter is? And is that the reason why my service engine light won't go off. Someone told me that it had to do with some box that holds wires under the truck. Is that true?
It's on the passenger side of the motor under the valve cover.
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
