Oil Pan Gaskets and Oil Sump Gasket Replacements

An oil pan gasket seals the sump to the bottom of your engine block, keeping oil inside where it belongs. Also called an oil sump gasket, it's an easy leak to miss until you spot oil on the driveway or a slow drop in oil level.

FAQs

1. Is an oil sump gasket the same as an oil pan gasket?

Yes. Oil sump is the more common Australian term; oil pan is the US term. Both refer to the same seal under the engine.

2. How do I know if my oil pan gasket is leaking versus another seal?

Trace the oil back to its highest point. If it centres under the pan itself rather than the front or rear of the engine, it's usually the pan gasket.

3. Is it expensive to replace an oil pan gasket?

The gasket itself is inexpensive. Labour cost varies depending on how much needs to be removed to reach the pan on your engine.

4. Can I reuse an old oil pan gasket?

It's not recommended. Most gaskets compress permanently once torqued down, so reusing one raises the risk of a repeat leak

5. Do you stock oil pan gaskets for trucks and commercial engines?

Yes, including heavy-duty options for Detroit Diesel and other commercial engines built for constant load and heat cycling.
