On my 427 CO there is a bypass going from intake manifold to water pump.
I am also in the process of changing the intake manifold gasket because I found an
oil puddle in several intake ports, with the
oil coming from between the manifold and the head. Probably the gasket is not sealing well, maybe it is the two cork end seals which prevents the intake from seating fully.
I would like to know whoever also has the bypass (if not plugged!) how you manage to fit the manifold taking care not to move the gaskets, not to disturb the end seals made with RTV and the the same time jiggle the sprout into the short rubber hose for the bypass ?
How many of you have the bypass plugged btw?
Do the gaskets go in dry or with some silicone around the ports or only around the water passages?
