Title: L6 intergrated cylinder head exhaust manifold removed
Post by: 79scott on August 03, 2015, 06:52:03 pm

Hey guys why would the truck leak antifreeze when I removed the exhaust manifold? Are there water jackets that run between the intake and exhaust manifolds? Also don't suppose I can get new smog tubes anymore?

I couldn't find NOS or aftermarket ones for my 1984.  As for the coolant question, not sure.

that's what I thought. I have new check valves, should be able to salvage the ends, may take a whack at fabbing up my own...
