Troubleshooting & FAQ
How do I confirm this gasket fits my engine?
The best method is to compare the part number (90430-14M09-00 or 90430-14228-00) with your service manual or the original part. While we list common compatible models like the F80, F100, F115, and F150, always verify the part number for your specific engine year and model.
What are the signs of a failing oil drain plug gasket?
The most common sign is an oil leak or drip from the drain plug area. You may notice an oily film on the lower unit or oil spots on the ground where the engine is stored. A crushed or brittle gasket should be replaced immediately.
Is it necessary to replace the gasket at every oil change?
Yes, it is highly recommended. The gasket is a single-use crush washer designed to deform and create a perfect seal when torqued. Reusing an old gasket significantly increases the risk of an oil leak.
Can I reuse my old oil drain plug gasket?
No. These gaskets are designed to be crushed once to form a tight seal. Reusing a gasket will likely result in an improper seal and an oil leak, which could lead to engine damage from oil starvation.
