Hey guys i need some help!! now
I was fitting on the new t-stat housing and i set the torque wrench to the wrong setting and i have now stripped the thread in the head..
anyone done this before ? what are my options??20180119_191906[345].jpg20180119_182225[347].jpg
Well the thread size on that bolt is an M6x1.00
Options:
Try to tap it 1/4-20
Get a heli coil for the M6x1.00 and fix the thread.
Go up a size to M7
I would take it out and try retreading it. If it seems to rethread, I would reinstall it with blue loctite. If it holds the correct torque, I would leave it. If it does not you will have to go up one size or helicoil.
Another idea would be to install a M6 threaded stud, hopefully, there would be clean threads further down that are not stripped. Add some blue Loctite and you would be golden.

Helicoil it, or go up a size.

Thanks lads never done a helicoil but it seems like the way to go.
Any tips ?? The bolt is out do i need to drill it out or just rethread it ?
I thought my M6x1.0 Vanos attachment bolts were stripped at one time because I had an oil leak that I could not diagnose. I re-threaded the holes to M7 and used exhaust manifold/head interface studs with exhaust manifolds nuts. The holes in the Vanos and gasket were already generous enough that I didn't need to enlarge them. I was lucky enough that the tap and die set I had contained the correct M7 tap.
Fixed lads
The thermostat housing thread is about 7mm longer then the standard bolt
I just ran the tap through it to clean it up and put a slightly longer bolt in it with some thread locker.
Thanks for the ideas.
