  • Rocker Cover gasket replacement help...

    hi just about to replace rocker cover gaskets and the inlet manifold gasket on a 6G72R SOHC motor,

    read somewhere that you need to use some sort of gasket sealant in the corners at each end of the cylinder heads where the gasket passes over the camshaft to ensure a good seal is this correct?

    Hi, I only put sealant on the rocker covers (in the groove) - in the same area you describe, not on the heads themselves. No leaks to date.

        This is one engine that has a high risk of developing a leak if not down righr.
        Clean the groove in the cover and also vigilantly clean the head mating surface right round.
        Main arwa of leak are the exhaust side and humps so be generous with rtv here, inlet side I just smear a bit on but not much. Finger tight bolts and then turn one full turn with a spanner. Let set for a good hour or so then do them right up.
