🔧 Install Tips

Torque Gently: These small bolts only require light torque (check manual for exact Nm). Overtightening will crush the new rubber and cause it to fail prematurely.
Clean the Surface: Wipe the mating surfaces of the cylinder head and cover clean before fitting the new seals to ensure an oil-tight seal.
Use Diagrams: Check the exploded diagrams in the product gallery to confirm exactly where this washer sits on your specific engine model.
