if it's comming out between cylinders, i would say hg!

 

sounds like a headgasket to me

 

just replaced the thermostat in feb. when i put the aluminum radiator in, its not leaking anywhere else you can clearly see that its seepage from between the head and block and i wanted to make sure that it was time to do the head
i was just wondering about the coolant loss really, there seems to be more of it missing than is on the ground but i guess it could be leaking while im driving and drying up before i see it

 

HG.....just replaced it on mine. it was doing the same thing

 

kinda in the same boat as me when I had the stock HG on mine if I really hot rodded it (like doing a brake stand) it would push water out the coolant overflow and the last time it blew out a heater hose (I guess 30 PSI boost into the water jackets is not good )

 

mine did the same as big bad diesel but mine was not the hg... the head was cracked between each valve...

 

Head gasket, most likely. I have replaced six factory head gaskets on 12 valves that are rotted out in the front right corner. 2 of the heads had to be replaced do to slight cracks no where near the corner. The new gasket is a updated part that eliminates this from happening (well see over time). Be sure to have the head checked out before you slap it back on.

 

if its a 89 or 90 head thats super common those 9MM injector holes cracked like crazy
