Good To Know

Q: How often should a valve cover gasket be replaced? A: Replace it whenever you remove the valve cover or notice oil weeping around the cover seam. Reusing an old gasket risks leaks after reassembly.

Q: Does this gasket require sealant? A: Follow the service manual for your GTX LTD 1503 model, as most marine gaskets install dry unless otherwise specified. Clean both mating surfaces before fitting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
