HELP!! need help diagnosing overheating problem

[El_Diablo]

ok so i haven't messed with the car since it happend this past summer, the problem is its bubbling coolant out of the overflow once the car is hot (only after it gets hot) and it looks like oil is making its way into the coolant, thing is, theres no coolant in the oil at all, correct me if im wrong but i drained the bottom layer of my oil and it looked fine with no water on the bottom at all (only drained the lower portion part way)

so i was thinking maybe the radiator popped and the coolant was getting forced out by the trans fluid, thing is the tranny dipstick looks clean and my sad attempt at taking it out and pressure testing it has yielded nothing..... so what could it be? what am i missing? the only possibility is that i popped a head gasket but how am i not getting any in the oil and im not really showing any vapor in the exhaust other than whats normal???

Does your thermostat work? What's the temperature when it starts bubbling out of your overflow?

poped the t-stat out... still happening to the best of my knowledge but i never let it get as hot, kinda hard to tell on the temp that it starts bubbling out at but i'll be driving around for a little bit at normal operating temp and im assuming the whole time its bubbling out and once the water is low is when it overheats, if i could just get the water to stay in i think it would be fine, lol

your head gasket is blown. the reason your getting oil in the coolant is because the oil is at a higher pressure than the coolant. the reason your coolant is bubbling out after it warms up is because that's when the thermostat opens and allows the compression out of the block. there's 2 ways to verify this:1st. do a cylinder leak down test (similar but not a compression test). 2nd: napa sells a kit for sensing combustion gases in the radiator.

KNEW IT!!! haha, thanks, just trying to prove my friends wrong..... i had someone help me lower the head on the gasket and i think he slid it and ripped the gasket so ohwell

are the fel-pro 1137's any good?

anyone?

I would recommed the Fel-Pro Multi Layered Steel (MLS) Head gaskets. They seem to hold up very well, and i have installed 2
sets on 2 different friends cars, with no problems.
