Check the oil level. If the oil level is low enough, the oil pump may begin to suck in air at high RPM, thus starving the lifters of the required pressure.
How does a hydraulic lifter work on an engine?
The pushrods actuate the rocker arms, which open the valves. Hydraulic lifters allow the valve lift to increase with engine rpm by filling up with oil as the oil pressure rises. The oil inside pushes the rocker arms further away from the camshaft, which causes the valves to open further.
What should I do if I hear a lifter in my engine?
If it’s too high, drain the oil pan and refill it with the appropriate amount of fluid. If it’s too low, add oil in through the filler cap until it’s up to the appropriate level.
