i recently had my turbo rebuilt by John Craig. Today i decided to take the gold bracket off the the turbo sheild bracket attaches to because i don't use a sheild and removed the bracket. I damaged the threads taking one of the bolts out because the oi return flange is in the way. Couldn;t get a smaller bolt in there, so i fired it up and exhuast leaks out the holes! WTF, i didn't think they went all the way into the compressor. My question is that i used a product similar to JB Weld to fill the stupid hole. Will this hold up?
