thanks for the tips.
I went ahead and took manifolds all the way off and decided to check the lower gaskets, well I have no idea what shape they were in as they peeled off with the manifold in pieces............
I got lucky and had every part in stock in this little town in Oklahoma except the lower gaskets which will be here tomorrow. So I spent the time cleaning the throttle body , manifold, and gasket surfaces.
I'm on my 6th can of throttle body cleaner i think....
I dropped 1 manifold bolt somewhere down beside the engine (not inside the engine) and can't find it so i'm going to pick one up at gm dealer and get the elbow, bolt and a thermostat with gasket there.
I'm also in need of a 1/4 inch torque wrench as mine doesn't go under 120 in .lb.
I am thouroughly pleased with my air compressor and air tools I bought only 3 weeks ago. It'* so much easier then fighting with those bolts where you can only move the wratchet 1/20th of a turn at a time. I'm having fun with this and hope I get back up and running correctly the first time.
Just to make sure on torque settings, I have lower intake bolts at 11 ft lbs (132 in lbs) and upper intake at 89 in lbs?
