Heavy-Duty Engine Oil Tank Gasket
Permanently Eliminate Oil Tank Leaks
One of the most common frustrations on the 998T platform is a persistent oil tank leak. The factory gasket can lose its sealing ability over time due to heat cycles, oil exposure, vibration, and repeated service, often resulting in annoying oil seepage that leaves residue on the engine, chassis, and garage floor.
After receiving countless requests from customers, Precision EFI developed a permanent solution.
Our Heavy-Duty Engine Oil Tank Gasket is manufactured from a premium chemical- and oil-resistant elastomer specifically selected to withstand the harsh environment of a high-performance snowmobile engine. Unlike the OEM gasket, it maintains its sealing properties through extreme temperature changes and prolonged exposure to engine oil.
The result is a durable, long-lasting seal that helps eliminate oil leaks for good.

- Premium oil- and chemical-resistant rubber construction

Whether you're servicing your engine or simply tired of cleaning up oil residue, this gasket is an inexpensive upgrade that provides long-term peace of mind.
Installation Recommendations
To ensure a proper seal and prevent damage to the fasteners:
- Torque specification: 70 in-lb (8 N·m)
- Use a Torx Plus 30IP driver only.
- Do not use a standard T27 Torx bit, as it may damage the bolt heads and make future service difficult.
Like many Precision EFI products, this upgrade was born from real-world experience and customer feedback. It's a simple, affordable solution to a problem that has frustrated 998T owners for years.
