I think i have blown a head gasket
Hey ,,sad news "I think" Well i got home tonight and walked around the front of the truck only to hear a bubbling noise from under the hood! I took a closer look and discovered that me radiator reservoir was full and bubbling,,, I do believe that I have blown a head gasket.. anyone else with a 1st gen have this problem?? my truck has only a few small modifications. I just installed a boost gauge and I am pushing about 25-30 psi max... not sure if this is common or have I done something to hurt my ol girl oh and I haven't ever had it overheat,,, at least I don't think so,,,,, Dave "administrator" your input would be good

Had the same thing happen to mine almost a year ago, I wound up re-torquing the head and it sealed itself up.
I got lucky with mine, I know it could pop again at anytime.
You'll probably have to put a head gasket in it, mine had a fresh one in it when it blew.

Blew one in my 1990 I had. The syptoms were exactly as you are describing. Head gasket isn't too bad to do and the new style gaskets hold better than the original on the 1st gens.

Does anyone know what causes this to happen? am I running too much boost?.. I haven't messed with the fuel screw,, all I have done is advanced the timing a little,a little different setup with the fuel pin and the high idle screw has been adjusted. I will admit that with the new mods, I have been more apt to push the "go petal" ..

Cylinder pressure is ultimately the cause of most head gasket failures, excessively advanced timing, too much boost all contribute to excessive cylinder pressure. I'm not saying yours is excessive, but its a good chance that the gasket was marginal and not up to the task.
Your case is probably more age related, figure if its the original gasket, its 17 years old with who knows how many thousands of miles. Probably due to start leaking coolant externally soon anyway, mine did, thats why I had a fresh gasket in it.
