I got a broken bolt on an alum intake manifold it is the left bolt for the TStat housing. So I got it out by drilling with a carbide dremel bit. I retapped it to the stock size, after taking out the junk. But the bolt is loose as I put it in. It can get tight enough to hold it, but if I torque it down too much it will probably strip the alum.
So should I drill smooth and retap with a larger tap to use a larger bolt or should I Helicoil to use the same factory bolts? Ive never helicoiled before though.
