help needed Pressurized cooling system
Ok i drove my car from work to my house which is only a few minutes and when i got home i noticed coolant coming out of the overflow. I was dark out so i couldnt really dive into it and see what was wrong.
It turns out that something is mmaking pressure in my cooling system. Headgasket bad? i dont see any smoke but, my friend told me to use some stuff from napa to seal the gasket. he said its a small leak in the head gasket making the compression go into the colling system. Should i put that stuff in it? Or just go all out and fix the head gaskets and have the heads checked for cracks and warping? they are gt 40's also what plugs should i use with a gt 40 head? its an 86 gt t top f cam eldebrok peformer 306 tko trans 373 gears i jus tpicked the car up for 4500

RE: head gasket problem
the oil is fine, not milky, the reason i think headgasket is because i tried to change thermostat and then i burped the cooling system and the upper radiator hose almost blew off because all the pressure and it gets hot and i shut it off and all the coolant pours outta the overflow

RE: head gasket problem
sounds like you didnt burp it enough. put your rad cap on so its on but not tight basicly the mid point. let the car idle for a good 15 minutes while watching your temp gauge and see what happens and did you put the t-stat in right?

ok i put the thermostat in right, i burped it and today i went out and moved it to the garage and the 3 min it was running the upper hose was so stiff i took the cap off and it was like a explosion of coolant. but the coolant wasnt hot it was still cold, i just want to know if it is a wise i dea to use this stuff from jegs, my friend used it on his circle track car when he had a head gasket going in the middle of the night. it worked

i couldnt run it for 15 mins after i tried to burp it the temp gauge went to 220 and i shut it off. its got a aluminum 3 core radiator elec fan edelbrock waterpump gt 40 heads bored.030 over edelbrock performer intake it also has a lil white smoke when i start it. also i want to know what plugs to ask for at the auto parts store for the gt 40 heads

thanks pro, why do they sell that sealant if everyone says its bad, the only people that have said its good to use are guys with race cars. and jegs tech line said it was good to use and wouldnt hurt anything
