- Remove the old oil pan gasket and thoroughly clean any residual gasket material or sealant from both the engine block and the oil pan surfaces.
- Align the new one-piece gasket onto the oil pan. No sealant is typically required.
- Reinstall the oil pan and tighten the bolts in the sequence and to the torque specifications recommended in your engine's service manual.

- Reconnect the battery, start the engine, and carefully check for any oil leaks around the pan.
Troubleshooting & FAQ
Will this gasket fit my Gen VI engine?
Yes, this gasket is designed for both Generation V and VI big block engines that use a one-piece oil pan. Always verify your specific engine model and part number.
What is PermaDry® molded rubber?
It's a high-performance material used for gaskets that provides a superior seal and excellent durability against heat, oil, and vibration compared to traditional cork or paper gaskets.
Do I need to use sealant with this gasket?
This is a one-piece molded rubber gasket designed to be installed dry. Generally, no additional sealant is required. However, always consult your engine's service manual for specific procedures.
What are the signs of a failing oil pan gasket?
Common signs include visible oil drips under the engine compartment, a consistently low oil level, oil residue on the outside of the pan, or the smell of burning oil while the engine is running.
How often should an oil pan gasket be replaced?
There is no fixed replacement interval. It should be replaced whenever the oil pan is removed or if it begins to show signs of leaking.
