Thread: Exhaust manifold studs.

I flipped mine around so there was more stud in the head - but did not tighten in the head fully - simply adjusted so that when fitted the ends of the studs were flush with the outer face of the nut on the manifold. No problems in 6000 km so far 😊

Yeah that is the other thing you cant screw it all the way in to the bit with no thread, but i was very tempted to do it

Another thing on the topic is i did try searching for discussion on if there should be a torque or high tight to put the stud in. I thought i found some people say same as the nut, but i think this is flawed and i never was able to get it that high nor wanted to try 100%, as the only thing creating resistance for torque is the wider non threaded bit of the stud, and this pushing against the head threads is not going to have the same holding power as all the threads in the head so you are likely, and i think i did a bit, wind it in too far flattening the starting threads. I ended up just dong it hand firm such that the non threaded bit was half in the hole.
