1967 Mustang Convertible
I will be installing a new cam, heads, intake, etc.. here in the next week or so. Usually I use blue rtv for timing cover, water pump and thermostat housing just a small skim on the gaskets. Then I would use the black for Intake end seal, oil pan, and valve covers along with the appropriate gasket. I have never used the grey but seems to say for high vibration. So what do folks typically use now days. Is grey better for some of these like around the water ports of the intake gasket?
