Product Details
If you're rebuilding the top end of your 1994-2004 Land Rover Discovery, especially with the Rover 4.0 or 4.6L V8 engine, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these engines, offering a reliable seal between the cylinder head and the engine block.
This gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with both aluminum and cast iron engine components. The compressed thickness is .040 inches, and it's designed for engines with 10-bolt cylinder heads and an 89mm bore, ensuring a precise fit for your specific application.
Because these are MLS gaskets, they don't require any additional sealants, making installation more straightforward. They are well-suited for engines that see regular use and need a dependable seal to maintain compression and prevent coolant or oil leaks.
