Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
A worn seal lets oil seep out or get burned. Replacing it is cheap; getting to it is usually the work. 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
- Lightly oil the seal lip before installation and press it in square so it does not cock or fold.
- Timing parts: Front crank and cam seals sit behind the timing belt or chain, so they are often done together.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
