Not enough oil pressure and / or the oil channel is plugged
the lifters may need adjusting or replacing. your engine not getting enough oil causes the lifters to make noise. not sure what motor you have in it but if it's an engine where you can tighten the lifters then you can buy a tool for it if you know what your doing
sounds like your oil is wrong viscocity and causes the hydraulic lifters to tap until oil thins enuff to work the lifters. if changing oil doesnt help you have a worn lifter
The ticking sound is coming from the valve lifters. When the oil filter is changed, air is introduced into the system, which causes air bubbles to form in the oil. This causes the valve lifters to "leak down", which is what causes the ticking sound. It can take several days for the bubbles to dissipate. It's annoying, but harmless.
Lack of oil lubrication to lifters
lifters are normally quiet in operation check oil level if fine check oil pressure if ok could be wear on cam and lifters if so replace
Insufficient oil or problem with pump.
The ticking noises is the lifters slamming into the valves. They are not receiving the amount of oil they require to lubricate properly. Either the oil level is very low or something else is seriously wrong. Continuing to run the engine like this will lead to very early engine failure.
your lifters are bad at least 1 of them or on a more serious note no oil in engine bad oil pump bad oil sending unit bent push rod blown engine
Fuel injectors don't tap. You are hearing the hydraulic valve lifters which are full of oil when functioning properly. Without sufficient oil they will make a tapping sound. If the car has sat for along time they will sometimes tap for a few seconds when you first crank it up. If yours valve lifters are tapping intermediately I would suggest checking your oil level and if that is OK you may have an oil pump going bad. If that should be the case do not drive the car as the motor will not get sufficient oil and will burn the bearings and kill the motor.
To replace the lifters on a Nissan 350Z, start by removing the valve cover and timing chain, ensuring the engine is at top dead center (TDC). Next, carefully remove the old lifters using a magnet or a pick tool, and clean the lifter bores. Install the new lifters, ensuring they are properly seated, then reassemble the timing chain and valve cover. Finally, check for any oil leaks and ensure proper oil circulation before starting the engine.

Yes, excessive oil can negatively affect lifters in an engine. Too much oil can lead to increased pressure, causing the lifters to become noisy or even fail due to improper hydraulic operation. Additionally, excessive oil may result in foaming, which can impair lubrication and lead to premature wear of engine components, including the lifters. It's essential to maintain the correct oil level for optimal engine performance.
