What it does
Seals keep oil in where a shaft passes through a housing, such as the crankshaft or camshaft ends. 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.
- 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.
