What it does
Buying the kit keeps the parts matched to each other and to your engine, and is usually cheaper than buying piece by piece. 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
- Have the block and crank measured before you order bearing and piston sizes.
- Machine work: Bores and crank journals often need machining before new parts.
- Oil pump: A new pump is cheap insurance in a rebuild.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
