While installing clean sealing surfaces well and apply sealant on oil pump gasket as well as rear oil seal retainer gasket surfaces.

It involves cleaning sealing surfaces, applying sealant, putting back the cup along with its gasketing material, screwing down bowl fasteners uniformly until fully tightened up and lastly lowering assembly down onto mountings again once torque has been applied to nuts.
