as the title states how do you know when your headgasket is blown need confirmation on some symptoms

 

here are the only ways i know how to tell. if there is oil in your coolant, if you see seepage around your head. if your blowing white smoke. Hope to have helped ya man. hope the best of luck

 

bump for more answers and thanks for the info its a negative on all of those i just suddenly over heated radiator pushes out coolant when engine is revved

 

that sounds like a blown HG. drain your oil and check for coolant in there.

 

I used to blow headgaskets all the time on my d series. It would always start pushing coolang out of the overflow bottle, overheating, but never any oil in the coolant. Thats only if the leak is real bad. I guess mine never were.

 

it pushes it out when the rad is open not into the overflow bottle

 

i think it is because i put water in the rad and it evaporated why i overheadted cause i just took it for a test run and it didnt overheat again radiater was still full of water gonna put coolant in it tomorrow still watching it though

 

you have air pockets in your coolant or your rad is plugged and needs flushing or replaced.. thats my .02

most of the symptoms for a blown HG are lose of power, overheating, over pressureized cooling system (my rad exploded in my face because of this on a previous car) oil in coolant or coolant in oil and milky looking oil (white, grey, etc)

im not sure if theres anymore but those are the ones i know

 

no loss of power just small bubbles coming out of the rad when revved dont know if this is normal

 

your **** my just need to be burped, have you tried this!!??

 

what do you mean? burped

 

...bleeding the air out of your coolant system. Very important step often overlooked by newbs.

 

yeah you just have to bleed it

 

what i did when i had air pockets


waited for the car to cool down a bit after a warm up drive, took the cap off, started the car and let it idle, and put in coolant as the thermostat let the motor suck in more from the rad, eliminateing the air pockets in the process, havent had a problem since

there may be a better way, but thats what worked for me

 

You might even see milky sludge under the oil cap.

 

believe me when i say...YOULL KNOW...haha!
