Ok. My latest DIY is to remove the turbos for a Kevin makeover. While removing the heat exchangers, on cylinder #3 (labeled 'B' ), the nut AND the whole threaded insert came out of the engine........on the others, just the nut came off leaving the studs intact (see "A")

Any tips when re-installing these when I replace the headers?
-Is this a problem?

Thanks

This is just a thought. I don't think this is a major problem.

Looks like the bolt threads on the part entering the head is cheaner than the threads sticking up out of the head. Might remove the nuts from the studs, clean up the studs with some brake parts cleaner, screw the studs into the head with some thread-lock, then install the turbos in place and istall the nuts with some anti-seize applied.

Will let the "experts" shoot me in the kneecaps.

 

Correct.

Clean them with a wire wheel and put a solid line of red Loctite on them when you put them in. You can install them with stud installers, or the cheap (and easy way IMO) with two nuts. Not a big deal, bud. No worries.

Edit.... looking again at that second photo: on the top thread of the lower threads on the righthand bolt... is that a piece of stripped Al. I see? Check to make sure that the stud didn't take any stowaway material with it when you removed it.

 

Kevin. The treads look ok...just filled with some gunk (anti-seize I think). You gave me a friggin scare though!

I wouldn't know a stud installer if I sat on it. Can I screw them in by hand, with Loctite, then install heat exchanger/nuts. Or do they need to go back into the head with more torque than hand tight? Thanks.....Marc

 

Hello Marc,

You would know a stud installer if you sat on one

I would do as recommended above... two nuts locked against each other then install the block side, remove the nuts and install head.

Nice car you got there mate

 

I'm not an expert either but I changed out those nuts when I had this apart on my car as their condition was similar to the ones you have removed. I'd change out the nuts, those two studs, and then use the two nut interference thing to reinstall them.

 

Marc,
You put the Cab up for sale once you finished all the DIYs. Can I have your TT when your done this time?
