An engine that purrs can be very satisfying — it’s a healthy, reassuring sound. but if your engine has started making a ticking sound while running,you may have to worry about your car.engine ticking noises are fairly common, and they can be either really bad news or not very serious, depending on the cause. in some cases, they can even be completely normal.Let's discuss the worst case first.
low oil level or oil pressure
This is the most severe — and potentially costly — cause of a ticking engine. a bad oil pump, worn engine or low oil level can cause this or other engine noises.
If you don’t have enough oil, or enough oil pressure, the top end of your engine will suffer first. gravity will keep what oil there is further down in the engine.
If oil isn’t reaching the top of your engine, you’ll begin to hear a higher-pitched ticking or tapping noise. more often than not, this is coming from the engine’s valve train components like lifters, rockers, camshafts and cam adjusters. the timing chain can also make a ticking or tapping noise if oil pressure is an issue.
