Frequently Asked Questions

Q: Does this kit include the valve stem seals and the main valve cover seal?
A: Yes, this master kit includes both premium valve stem seals and a formed rubber valve cover gasket, giving you everything needed to seal the top cylinder head configuration.

Q: Are the oil seals included in this kit up to OEM quality standards?
A: Yes, all oil seals provided in this Moose Offroad kit are genuine OEM-quality replacement seals built to stand up to tight clearance friction and aggressive synthetic engine oils.

Q: Is a mechanical water pump seal included with this package?
A: No. As noted by the manufacturer, the mechanical water pump seal is not included in this specific layout and should be ordered separately if you are replacing the water pump shaft components.

Expert Pro-Tip: Gasket installation lives or dies by the preparation of the mating surfaces. Never use a metal razor blade or aggressive wire wheel on lightweight aluminum crankcase halves, as you can instantly gouge the metal and create a permanent leak path that no gasket can stop. Use a specialized plastic gasket scraper and a high-quality solvent or brake cleaner to dissolve old material. When installing the vital oil seals, coat the rubber lips lightly with fresh engine oil or assembly grease to prevent a "dry start" burn, and tape over any sharp splines on the transmission shafts so you don't cut the new seal edge during slide-on assembly.
