These coatings provide a micro-seal for fluids against the head and block surface.\u003c\/p\u003e\n\u003cp\u003eThe layers of the MLX gasket act as a spring, protecting against blowout and increasing active seal height by compensating for increased head lift.\u003c\/p\u003e\n\u003cp\u003eMLX Head Gaskets are different from MLS because they feature an extra,specialized ‘stopper’ fold-over layer. This layer provides a torque limiting surface that prevents yielding of the combustion seal.\u003c\/p\u003e\n\u003cp\u003eIt’s important to note that MLS\/MLX head gaskets are not compatible with engines that have O-rings or receiver grooves around the cylinder bores. These gaskets require smooth and flat surfaces to seal properly.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cem\u003e\u003cstrong\u003eInstallation instructions:\u003c\/strong\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eMake sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant.\u003c\/li\u003e\n\u003cli\u003eInstall the MLX gasket on the engine block and ensure that it is properly aligned.

This will ensure that the gasket is properly seated and compressed.\u003c\/li\u003e\n\u003cli\u003eIt is recommended to not use any additional sealant on the MLX gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\u003ch3\u003eAvailability and delivery\u003c\/h3\u003e\u003cp\u003eSupplied to order.
