• Tapping the hole with a special Heli-Coil Tap, or equivalent. • Installing an insert into the tapped hole to bring the hole back to its original thread size. STANDARD PROCEDURE - FORM-IN-PLACE GASKETS AND SEALERS There are numerous places where form-in-place gaskets are used on the engine. Care must be taken when apply- There are numerous types of form-in-place gasket materials that are used in the engine area. Mopar T Engine RTV GEN II, Mopar T ATF-RTV, and Mopar T Gasket Maker gasket materials, each have different properties and can not be used in place of the other. MOPAR T ENGINE RTV GEN II Mopar T Engine RTV GEN II is used to seal components exposed to engine oil. This material is a specially designed black silicone rubber RTV that retains adhesion and sealing properties when exposed to engine oil. Moisture in the MOPAR T ATF RTV Mopar T ATF RTV is a specifically designed black silicone rubber RTV that retains adhesion and sealing properties to seal components exposed to automatic transmission fluid, engine coolants, and moisture. This material is avail- MOPAR T GASKET MAKER Mopar T Gasket Maker is an anaerobic type gasket material. The material cures in the absence of air when squeezed between two metallic surfaces. It will not cure if left in the uncovered tube. The anaerobic material is for MOPAR T GASKET SEALANT Mopar T Gasket Sealant is a slow drying, permanently soft sealer. This material is recommended for sealing threaded fittings and gaskets against leakage of oil and coolant. Can be used on threaded and machined parts T Gasket Sealant is available in a 13 oz. aerosol can or 4oz./16 oz. can w/applicator. FORM-IN-PLACE GASKET AND SEALER APPLICATION Assembling parts using a form-in-place gasket requires care but it’s easier than using precut gaskets. Mopar T Gasket Maker material should be applied sparingly 1 mm (0.040 in.) diameter or less of sealant to one gasket surface. Be certain the material surrounds each mounting hole. Excess material can easily be wiped off. Mopar T Engine RTV GEN II or ATF RTV gasket material should be applied in a continuous bead approximately 3 mm (0.120 in.) in diameter. All mounting holes must be circled. For corner sealing, a 3.17 or 6.35 mm (1/8 or 1/4 in.) Mopar T Gasket Sealant in an aerosol can should be applied using a thin, even coat sprayed completely over both surfaces to be joined, and both sides of a gasket. Then proceed with assembly.
