I just got my motor back from my machinist (very familiar with evos) Its a 2.4, block and head were machined flat and im running an oem evo 9 headgasket bored out. I have not started the motor yet, I am still waiting on a few parts. I decided to pressure check the cooling system and noticed the headgasket is seeping coolant very slowly. Is there any chance this will seal up after it heat cycles? Torqued to 100 ft lbs and using map h11 head studs.

 

Nope. Take it apart - see what is wrong.
