Did I Cook A Head Gasket? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Finally got the rebuilt engine running, couple of big( i think) problems surfaced. first of all, didnt have any coolant, so i filled the rad with water, simply to be able to run it long enough to time it. the engine ran about 5 minutes, off and on, at anywhere between 600 and 3000 rpm. the engine seemed 2 be thorwing a lot of heat, so i idled it down and let the fan cool things about. i then noticed that the exhaust had a black almost diesel look to it. im wondering, did i cook a head gasket? im not sure if this is simply assembly lube, or if i cooked a gasket. i didnt notice what the exhaust looked like before this. could it just be oil and crap burning off? i really hope someone can tell me, cause i am really dissapointed. i also noticed that my temp gauge stopped working, simply because the ground on the gauge is no good. can someone help me, please? im really worried
thanx dale

if it was a head gasket and you were getting water in the cylinders the exhaust would have been white, like steam. if it was oil/lube it should have had a blue -ish tint to it. Since you said it was black look to it I would say your carb is dumping way too much fuel. excess gas will cause the black smoke. It could also had been caused if you had just rev'ed it up and let off and then looked back at the pipe, sometimes you will get a little smoke then.

Orange72350: I am curious on the status of your motor and what was producing the black smoke. Just a curious mind that is hoping everything is all right.

BTW: just for your peace of mind. I will second the fact that a blown headgasket will produce white smoke. My brother has been there, done that.
