So I finally got my topswap finished up and can start the car now it runs great for about 30 seconds until a vacuum leak opens up and keeps me at 2k rpm. I tracked it down w brake cleaner and found it getting sucked in right behind the thermostat under one of the 3 long bolts that hold the sc (gen 5). I tried to give it a couple turns to see if it would close it up at all but I ended up stripping the threads on the intake . So I took off the sc got a new gm gasket, put a helicoil in the threads I stripped, and got them all torqued to 17Lbft. Still has the same problem in the same spot I was thinking maybe the sc or intake could be warped right there because of the 2 water ports is that common ?
