Michigan Motorsports LS Oil Cooler Bypass Plate Gasket 12611384
Fits 1997-2013 LS-Based 4.8L 5.3L 5.7L 6.0L 6.2L V8 Engines | Oil Cooler Bypass Plate Gasket
Replace a worn, damaged, or missing oil cooler bypass plate gasket with this LS Oil Cooler Bypass Plate Gasket 12611384. Designed for 1997-2013 LS-based V8 engines without an engine oil cooler installed, this gasket seals the oil cooler bypass plate to help maintain proper oil system sealing during engine service, repairs, rebuilds, and LS swap projects. This is the correct style gasket for non-oil-cooler applications and is commonly used on 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L LS engines where the factory bypass plate is retained.
Key Features & Benefits
- Oil Cooler Bypass Plate Gasket: Designed to seal the LS oil cooler bypass plate on compatible engines without an oil cooler installed. This is a simple but important gasket when servicing the bypass plate, refreshing seals, or assembling an LS engine.
- Fits 1997-2013 LS-Based Engines: Compatible with a wide range of Gen 3 and Gen 4 LS-based V8 engines including 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L applications. This makes it useful for LS cars, Vortec truck engines, and common LS swap combinations.
- Ideal for Repairs & Engine Service: A fresh bypass plate gasket helps restore proper sealing when the original gasket is flattened, damaged, leaking, or removed during engine work. It is a practical replacement during oil pan service, engine resealing, rebuilds, and maintenance.
- Correct Non-Oil-Cooler Gasket Style: This gasket is intended for engines using the oil cooler bypass plate, not engines equipped with an oil cooler. Using the correct gasket style is critical because oil cooler applications require a different gasket with two ports.
- Great for LS Swaps & Rebuilds: Perfect for builders refreshing an LS engine, replacing missing gaskets, or assembling a non-oil-cooler setup. Keeping the correct sealing components on hand helps make the job cleaner, faster, and more dependable.
