95 chevy 1500 coolant problem
#1
So I changed the intake manifold gaskets 183,000 miles because it was leaking coolant, so i replace them(fel-pro MS 93317) and i drained the oil before hand, and i get done, and i start to put coolant back in it, COOLANT IS COMEING OUT THE DRAIN PLUG, for the oil. so im like what th fark, and so i rip it all back apart to see if any gasket slipped because of the rtv i put on there, NOPE, everything looked strait, so i sealed all the coolant holes on the gasket, put it back together, and it still does it, does anyone know what the hell could be goin on, i have to get it back working by sunday night. Thanks for help..

The only things that come to my mind right now are:

1) Are you sure you have the right gaskets?

2) Did the manifold cooling passages get a hole in it somewhere? Check the passenger rear heater pipe coolant passage On V8's

3) You are pouring the coolant in the proper fill location right? (just a joke)Wink

If I remember correctly those intake gaskets are plastic with neoprene around all of the holes. You aren't supposed to used sealeant on them. Using sealant on those gaskets can sometimes cause a leak.

I just changed the gaskets on my k1500, and i was careful and drained the coolant and than used a vacuum to help drain the rest. as you put coolant in does it pour out the oil drain? I didn't have any coolant leaks, but if any got in the lifter valley than it would drain out.

i would say with fel-pro intake manifold gaskets you arent supposed to use selant, at least any i have seen you dont

figured it out, i missed a tiny piece of the old gasket around the water jacket, maybe the size of a match tip, i guess that would cause it, anyways its back up and towing so thanks guys
