Stainless steel exhaust studs

[Morpheus]

One last question:

What should I use to actually remove the studs? I have seen the double-nut method and even looked into a stud extractor. I have read that vice grips aren't a good choice. What is the preferred way on a DeLorean?

The best tool is a dedicated 7mm stud extractor as it grips the best and can fit in tight places. They cost a bit but will save you a lot of grief if you want to do the job right. There is an Assenmacher #200-7 7mm extracter on amazon for about $38- & $8- shipping that will make you feel like a pro when doing this job.

You guys are making this sound way too easy. You're supposed to say removing the exhaust studs are an impossibly hard task so I'm not tempted to buy a SPEC 1 exhaust.

Difficulty would be relative to the number of and or location of existing broken studs.

I have a friend that has 2 broken studs (empty holes) in the RH manifold. One rear with easy access. One all the way forward (PITA access) but doable.

I just remembered the O2 sensor will need replacement. Is there a cross reference part, or does everyone just grab one from a vendor?

I've time-serted broken studs in every location over the years without ever having to R&R a motor for access. It is entirely doable with the correct tools and experience.

I've had the experience of removing the forward most broken stud on each side. Definitely doable with some forethought. I made a drill jig guide and bolted it up to the head using opposite corner threaded holes in the head. I bought a 90 deg air drill A couple short extractor sized drill bits. I was a bit fortunate that the flush broken piece was not frozen tight to the head. They backed out remarkably easy. I did not need to do any thread repairs.
