Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Worn rings show up as oil burning, blow-by and low compression. 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
- Check ring end gaps in the bore before installation and stagger the gaps.
- Bearings: Rod and main bearings are usually replaced at the same time.
- Gasket set: The engine comes apart for this job.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
