Threaded Exhaust Manifold

[bitcrusher]

When I removed exhaust manifold to change engine mount I noticed 1 bolt had been changed for a longer as due to a threaded hole though I tightened it to much and its I <3 Bananased, also the same with another bolt.

So I have 2 threaded holes which are minced and was thinking about fixing and replacing with studs? Whats the longest bolt I can put into the head.

Some suggestions and information would be appreciated thanks

that's pretty standard as there's a couple of longer ones for the engine removal bracket and the heat shield... and if you move these you have to change those bolts if you wish to not cause damage to the threads. helicoil the threads and upgrade to studs or go with replacemetn bolts.

When I purchased car didn't come with heat shield currently in the search for one.

how long of studs could I use? Wondering if I could use larger studs to solve the problem

just buy the stud kit that goes with this car, if you think you want them specifically. I doubt you'd be able to do it the way you're suggesting without creating other potential problems.

need to fix threaded bolt holes before just putting in studs
