Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Visible oil leaks around the perimeter of the valve cover are the first sign of a failing cap or gasket. If left unaddressed, these leaks can worsen, leading to low oil levels and potential engine damage. Persistent oil leaks can also create a fire hazard in the engine compartment.

Installation Tip

Always clean the mating surface on the cylinder head thoroughly before installing the new valve cover cap. Overtightening the mounting bolts can warp the cover or damage the gasket, leading to new leaks.

Service Note

Inspect the valve cover gasket for cracks or hardening and replace if necessary during valve cover cap replacement.
