Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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

Failure Symptoms

Initial signs of failure may include a persistent low oil pressure warning light or audible engine knocking. If left unaddressed, the engine may suffer from accelerated wear on critical components due to inadequate lubrication. Continued operation without addressing the issue risks severe internal engine damage.

Installation Tip

Ensure the valve seat area is completely clean and free of debris before installation to prevent leaks. Do not overtighten the valve, as this can damage the threads or the valve body.

Service Note

Inspect the oil pump and oil filter for wear or contamination when replacing this relief valve.
