When to Replace or Reuse Lifters

New Flat Tappet Lifters are ALWAYS required for flat tappet cams. Used flat tappet lifters will have a wear pattern on the face. The wear pattern on the camshaft and lifters starts during the Break-In Procedure. This is one reason why following the break-in procedure is so critical.

Do hydraulic lifters need adjusting?

One of the advantages of hydraulic lifters is they don’t normally require adjustment other than the initial installation. However, there may be situations where the valvetrain is partially disassembled, during the installation of roller rocker arms as an example, which will require adjusting the lifters.

Cam lobes can also wear quickly when using high Valve Spring Pressure. These high spring pressures will cause the cam to wear faster than normal. These engines, however, are built for performance, rather than longevity.

Will thicker oil stop engine ticking?

When you have low oil volume or low oil pressure, you’ll commonly hear a “clattering noise” coming from the engine’s valves. Adding more oil will make the noise go away, but it won’t solve the underlying cause of the noisy engine – the oil leak.
