What's a Lifter?
Each valve has a hydraulic valve lifter. The rocker arms, which are small rods that attach to the valve's cylinder, connect it with the rocker cylinder. The lifter’s job is to help open and close the valve with the assistance of the rocker arm.
Tickle noise is possible if there's a problem with either the engine or lifter. It is less likely that you will need to make major repairs when the problem has been addressed quickly.
A hydraulic lifter can be installed between the engine's camshaft, and engine valve depending on which engine model you have.

Lifter tick causes
1. Petroleum Contaminated
Oil is essential for the motor to function properly. It wears out the lubrication, which causes the engine to not work as well.
It’s important that you perform regular oil changes to combat this issue. Additionally, change the oil filter to ensure there’s no unnecessary contamination.

2. Too Much Oil
Oil is essential for the engine to run smoothly. If the oil levels get too low and the engine can’t run its best, the lifters may not function properly.
Even if the engine isn’t making noise, you must resolve the low engine oil issue promptly. The wrong oil could cause irreversible, serious damage to your engine.
3. The wrong oil type
All engines run different oil types. If you wish to have proper operation, it is important to pay attention to the viscosity rating.
Oil that has a higher viscosity is better for colder areas. It can also flow quicker. The engine's performance will suffer if the oil becomes too thick when temperatures drop. Summer months call for oil that is thicker. You should be able to determine what oil viscosity is appropriate by checking the vehicle owner’s manual.

4. Bad Lifter
If the problem isn’t related to the oil, then the lifter itself might be to blame. You might hear the lifting mechanism make a clicking sound, which can get worse.
It is impossible to repair a damaged lifter unless you replace it. If you don’t take action soon enough, the problem might create a misfire as the valve no longer opens as it should.
5. Bent Pushrod (Some engine types)
The car’s age and the way it is driven can have a profound impact on how the pushrod operates. Over time or after a lot of abuse, it’s possible for the pushrod to bend.
When this happens, the lifter can’t function correctly, leaving you with an engine tick. You can only fix this problem by changing the bent pushrod.
How to fix a lifter tick
1. Make sure your engine oil is clean
Maintaining your vehicle should always be your first priority. This is why you must change your engine oil and filter regularly.

It is necessary to replace the pushrod if it becomes damaged. Similar applies to the rocker arm.
However, neither of these fixes is inexpensive, which is why it’s important to maintain and care for your engine in the first place. It can take a lot of time and require specialized knowledge to replace engine parts.
