yeahh, scott its not the gasket that goes bad, its the whole upper intake.
If you go through Bill's thread, you will find that on an n/a engine, there is an egr stove pipe that is presses into the lim, this pipe goes up through a tunnel into the uim (upper intake manifold), on each side of this tunnel, there are two coolant passages to allow coolant up into the throttle body to keep it cool...honestly doesn't help in my and most peoples opinions. After years/milage....the egr tunnel goes through many heat cycles and wears through to the coolant passages because the stovepipe is right against the tunnel.
The revised Dorman Intake Manifold ( PN# 615-180)...which can be purchased at most every parts store, most all of them will have it in stock, comes with a new stovepipe that is the same base diameter to be pressed in the lim, but has a smaller pipe diameter as to not be so close to the tunnel walls.
