I finally got my agency power hybrid valve, i was ready to put it on and of course things go south. I went to take one of the flange bolts off the stock diverter valve and when i noticed that there was no resistance when trying to ratchet it off its then i realized the bolt was snapped in two. So half the bolt with the head is out and the threaded half is still in the intercooler flange. A couple things that i also realized is that this means i have been driving around with only one bolt holding down my diverter valve, the new aftermarket valve doesnt even line up perfectly without both bolts being in place, and finally i don't know how to tap and drill out the rest of the bolt. I put the stock diverter valve back in place and that still lines up perfectly, so i just attached the hoses again, re-tightened the one bolt that was holding it in place and left it be. I turned on my car to see if its functional and yea it works but now i don't know by removing the stock valve from its original place, would this cause a potential leak area if i drive around. the valve seems tightly fitted and it doesn't move even with the one bolt holding it in place. But, i don't wanna risk any further damage. What is the best way to approach this situation. I already have my friend who is a subaru mechanic coming over later to try tap and drill out the rest of the bolt.
