Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Replacing a gasket is usually more labor than parts, so it pays to replace any others you disturb on the way in. 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.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
