How do you stop a lifter from tapping?
Lifter tick can happen due to dirt in your engine oil, low engine oil levels, improper lifter spacing, or overall faulty lifters.

Is thinner or thicker oil better for lifter tick?

What causes a lifter to get stuck?
When the lifter sits for too long a period without being run, the oil will drain out of it. This allows the lifter to completely collapse until the lifter can be filled again. During collapse, both sides (top and bottom) impact each other and thus creates the noise you are talking about.

What happens if a lifter goes out?
When the plunger inside of a lifter fails, it’ll fail to maintain oil pressure and will remain in a collapsed state at all times. When that happens, the lifter will fail to take up lash in the system, which causes parts inside to hammer against each other during initial contact.
