Troubleshooting & FAQ
How do I know if this gasket set fits my specific engine?
This gasket set is specifically for GM 3.0L (181 CID) 4-cylinder marine engines that use a two-piece rear main seal. Please review the compatibility tables and compare the part numbers to your existing part or service manual. Verifying your engine's seal type is crucial for a leak-free installation.
What are the signs of a failing oil pan gasket?
Common symptoms include visible oil drips under the engine, a consistently low oil level, the distinct smell of burning oil, or smoke from the engine compartment as oil contacts hot surfaces. Prompt replacement prevents engine damage from oil loss.
What is the difference between a two-piece and one-piece rear main seal?
A two-piece rear main seal consists of two halves installed around the crankshaft, typical in older engine designs. A one-piece seal is a single circular unit pressed into the block or a retainer. This gasket set is only for engines with the two-piece design. Using the wrong type will result in significant oil leaks.
