Where are the tappets on an OHV engine?
The tappets can be seen sitting just above this OHV engine’s camshaft. As stated above, a tappet sits on the end of pushrod or rocker arm and the other end interacts with the lobes of the crankshaft, initiating the motion of the valve to open and close as the cam profile rotates around its own axis.
What does a tappet do in an overhead cam engine?
This is slightly incorrect, as the noise can be down to a multitude of components within an engine’s valvetrain. However, a tappet (also known as a cam follower or lifter) is a small cylindrical mechanism which is attached to the end of the pushrod(in overhead valve engines) or the rocker arm (in overhead cam engines).
Why does my car make a tapping sound when I Change Oil?

What should I do if I hear a ticking noise in my engine?
Check Oil Level – You should begin by checking your engine’s oil level. It is possible that the oil was not filled to its full operating capacity when changed. If this level is indeed low, add oil until reaching capacity. Check for Leak – Visually inspect your oil filter and oil drain plug for signs of escaping oil.

When does the variable valve timing ( VVT ) start?
Typically the VVT system does not activate until the engine is at higher RPM or is introduced to load bearing situations like driving uphill. However, if the VVT solenoid is malfunctioning, it is possible that it will introduce additional engine oil to the VVT gears.
What should I do if my tappety engine is not working?
If these changes make no difference to the tappet noises, a full tappet adjustment should be the next move. Using a feeler gauge to wedge between a rocker arm and the valve stem, a factory setting can be found through a workshop manual to adjust the valve adjustment screw to the correct clearance.
