What it does
Lifters wear together with the cam lobes, which is why they are usually replaced with the cam. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Soak hydraulic lifters in oil before installation and set preload as your engine requires.
- Camshaft: Flat-tappet lifters should not go on a used cam.
- Pushrods: Check pushrods for straightness while they are out.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
