What it does

An old gasket gets hard and shrinks with heat cycles, which is when leaks start. A new gasket restores the seal. 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

  • Clean both mating surfaces completely and follow the bolt torque and sequence for your engine.
  • Sealant where called for: Some joints need a dab of sealant at corners or seams; others must go on dry.
  • Bolts and grommets: Rubber grommets and old bolts are worth replacing if they are damaged.
  • 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.
