Well it lasted 5 months. Now it is apparent that I need to have this welded up and retapped. Anyone know what the cylinder head on a pinz is made out of?? I expect it needs TIG welded. Both places I checked with asked me what it was made of and I didn't know.

WEll tapped the hole and threaded in the insert. It looks pretty good and the manifold seems to have snugged up pretty good. We will see how it goes tomorrow when I drive it into work.

Yeah, I will probably have to have someone weld in that hole at some point. right now I need to see if the insert will even thread in.

So I fabbed up this little jig and it seems to have worked pretty good so far. You can see how far off the muffler shop was from where the hole should have been.

Joe, that is what I have been thinking . Sort of like an exhaust flange with a short section of tube over one hole to keep the drill bit straight. O could bolt it in place and use it as a jig.

well if it breaks off again it may be a royal pain to get out is all. but actually no, aside from that I can't think of a good reason.

I was thinking about having a jig fabbed up to bolt in place on he existing stud with a tubular extension to keep the drill square to the cylinder head but that in itself might be a project. Pulling the engine and taking the head off would probably be best but I sure don't want to undertake...

So I broke off a manifold stud and buggered it up a bit. I then took it to a local muffler shop who got the stud out and replaced it. They assured me the stud was in there just fine. That stud is now road debris somewhere. I am intent on fixing this myself and have the correct Timesert kit...
