Need help! IH up pipe install

[BoarKilla24]

I cant get the up pipe to tighten to the collector tight. The flange still moves and the bolts are on pretty tight. I dont want to break the bolts. I dont know what the deal is. Any info will help

Thats what ive been using. I just dont get why the up pipe is not tightening down. The bolt almost feels like it is bottoming out. I already had to extract two broken bolts from last night. Im not understanding why they wont bolt up tight without breaking.

The new collector probably isnt threaded properly. Its a bit of a known issue, just not known by many.

Try running a tap through it to clean up the threads

The bolts go in good it just seems like the bolt is bottoming out on the cast. The tip of the bolt was messed up. Ill try and post a pic.

Try adding a washer or two.
As long as you have enough threaded in there it should be fine.

Heres the bolt

probably sound dumb, but you using the right bolt in the right location...have yet to hear this problem.

Or, hit up hardware store, get smaller grade 8 bolts?

It said use the short bolts and in the kit it came with long bolts (for the manifold) and short bolts which i assumed was for the collector.

I'm sure its just not threaded properly. Pop a couple washers on there and call it a day.
