So first off the truck is an 86 bj70, around 322k km on the truck, i just put a td04 13t turbo on it but havent yet turned up the fuel. I wanted to baseline it first to see everything working after i put it all back together. The head was cracked a wee bit when i took it off to replace the precups so it was replaced with a new unit, injectors were rebuilt at 1850 psi, injection pump was retarded about 1mm.
I put a frozen boost water to air intercooler on it. Head was decked at the machine shop.
So after the first drive i realized that the coolant overflow was slowly spitting out some fluid, i figured that it was just burping some air so i filled it up after it cooled and drove it the next day. Same thing the next day too, and the bubbles coming from the overflow tube were fairly constant. The water temps started to climb as well about 200+, and it got up to 220 or so for a very short period, so i pulled it over and let it cool.
The egt's were higher than i figured they should be as well, especially having an intercooler installed and no fuel increase.
I'm starting to think the head gasket didnt seal, classic hg symptoms......
I used a toikio (probably mis-spelled) MLS gasket from radd cruisers, looks identical to the toyota one.
What are some reasons that it may have not sealed? Could this issue be something else?
