3.8 head
hope i don't get stoned for this. i'm working on a 92 taurus that has a coolant leak i went to pressure test the system and when i would try to pump it up coolant would shoot to the pass. fender. i looked at the head and on the side of it is a 1/4" diameter hole that is smooth and looks machined i was hoping someone knew what this hole was for. thanks for the help
