Well, I am not having a good new year. I removed my intake manifold to fix a coolant leak and broke off one of the bolts (the rear right one on the passenger side) I drilled a hole in it to put in a screw extractor and the screw extractor broke. I bought a helicoil kit and began to drill out the hole.using a 7/32 bit. The hardened steel bolt was difficult to drill, and I guess the aluminum was easier. I put the intake back on just to line the holes up and I drilled a little too much too much to the left and coolant started spewing out of the hole I was drilling. I also see coolant in the right rear intake hole indicating perhaps that it went to the cylinder? I uploaded a picture of the hole in the archieves under ruined engine. I am guessing this is the case right? Is there a way to fix such a hole other than complete engine replacement?, Or am I just screwed. Is there hope for my car, can it be welded? Joe P. 6808 17167
