Default BOV bolt broke through TMIC tank

So... I had my clutch changed at a "reputable
shop in my area, and the shop broke my top mount intercooler, and denies ever taking the BOV off. I knew that they put different bolts on the BPV, but anyways...

Once I took the bolts out, after observing a leak through the bolt holes when doing a pressure test, I realized that not only are the threads stripped out, but they impacted too long of bolts into the bolts, which ruptured through the back of the bolt hole, into the tank. This is my daily, and I can't really take off of work due to having accepted a new job.

Any ideas for ways to seal this up?? Thanks guys!

i think those ebay godspeed intercooler bpv holes pass though. it did in my case and i used teflon tape arond the bolts for a better seal but i wouldn't recommend doing that since its so close to the throttle body.. unfortunately i just replaced my tmic with a sti.. i really dont know what kind of advice to tell you. anyone else?

pick up a used sti tmic locally, or even a stock wrx one for cheap/free for now until you can get it figured out if you really have to drive the car right away

Yeah, it's a Turbo XS TMIC. My pops was suggesting that I re-tap it a size bigger, and put some longer bolts in, with RTV or something on the threads, with a rubber washer on the outside. Do you guys think that might hold? I'm running 18 PSI with stock STI turbo.

That would definitely hold for a while, just pressure test it again. Even if it leaks at 10 or 15psi, it will at least let you drive around for a while.

Well, you can do that and find out, but i don't think that's a permanent solution.

Still ended up leaking through, after changing that out.. Dang. Any other ideas guys, aside from getting it re-tapped?

Just helicoil it? As long if you have enough room and material thickness...
This should work?
Try to post a pic of the problem you are having, perhaps we could help out more if we can visualize what is going on.

Here is a picture of the hole, and the back of it sheared through.

Re-tap it in a larger size. Clean out the TMIC for any metal shavings. Then put the bolt on with blue Loctite on the threads.

might be able to get some aluminum rod, thread it and seal the hole with loctite...then drill and re-tap to the proper depth.
