Appreciate that Schwann. I’m near Syracuse, there are a few sports car repair shops here as well as a Porsche dealer. I had some work done at an Indy shop on my wife’s Volvo and he did a great job, very reasonably priced. He’s my go to guy for the Cayman. I have to wait him out as he works alone and shop is always full of bmw’s Mercedes, Audi. All high end cars. It will have to be flat-bedded there. It would be pricy if it needed to be trailered or flat-bedded to go to Conn. if my Indy shop can’t fix the damage, I’ll have to consider other options including selling the car as is.

Agreed... "upstate" NY can mean a lot of things, and NY is giant as well, so I get it!

I agree, bringing it out here may not be in the cards. Sounds like you do have a good shop to do it... just have to be patient, I guess. I know it sucks, particularly when you see the sunny scenery outside!

Good luck!

I have heard nothing but high praise from Musante motor sports. If I were closer, I would definitely consider him. Porsche owners on the Pelican website have had work done by him with no complaints and were very happy with his work. The Indy repair shops around here that work on Porsches are iffy, expensive and your car will be in the shop for repairs a longggg time. My friend brought his beautiful 356 coupe in one of the “specialty foreign repair shops” in Syracuse for a clutch cable replacement. 4weeks and $3500.00 later he got his car back. He got ripped off big time. They did a bunch of unauthorized work, he did not get back any of the old parts, he asked for a NYS inspection, they refused because of “bad” tie rod ends. I told him to get the car the hell out of that place before they did some real damage to it. I tend to all the work on my cars including this Cayman and 3 other Porsches I’ve owned over the years. I know my capabilities and when to stop and get the car to a pro before I do something stupid and expensive. This is a perfect example of me doing something stupid and probably expensive lol!

True that….thought I’d be o.k. Using a torque wrench. Apparently not.

Do you think a bit of thread is cross-threaded and holding the extractor in place? Like a circlip or something almost?
Ugh.
Don't despair though!
I think the indie will get it out. Too bad you have not had any success solo, yet.
Cheers

Maybe, it’s stuck on something. Made a jack screw to try to pull out the extractor. Welded a section of threaded rod on a 13mm socket. Epoxy the socket onto the extractor, after it sets will try to jack the extractor out. Fingers crossed.

Successfully removed extractor using homemade jackscrew. Planning on using snap on straight fluted extractor tomorrow. No joy with Indy mechanic. I presume he doesn’t want this headache. Anyway made a longer socket for the extractor hex that slides over the fluted section. maybe this will work. Attached photos show the longer socket, shot of the remains of the plug in the head and jack screw.

At this rate, I see you eventually coming up with some new tool solution that you could market for anyone else with this problem! Best of luck.

Default Plug removal update

Next week gonna try this after much thought and advice, left handed 11/32” drill bit to drill out more of the shell and hopefully relieve tension so my straight fluted easy out can remove the rest of the shell and not damage the threads in the head. Machinist friend is turning a drill guide for me that will fit snugly in the plug access so I can drill straight into the shell and not damage threads in the head. Right angle drill should fit in the tight space to allow me to slowly drill out the shell. Who knows, maybe the shell will come out with the drill bit. will order bit from McMaster Carr tomorrow. Keep everyone posted on the results.

Wat's preventing you from bringing it to an experienced mechanic? The more you play with it, the more damage you can cause and harder to make it out in one piece. Suck it up to the experience, let your ego go, spend some money, get it done in a timely manner and enjoy the rest of the summer and not worrying about the dang thing

i suspect (just guessing) the OP may think that the response from a shop would be. 1) we'll remove the engine and transmission, then remove the head and send it to a machine shop and have them do their thing (helicoil-ish). if they can't we can sell you a rebuilt head, or a new one, your choice, then reassemble the engine and re-install it. ...price?... about $4,000-10,000 depending on whether the machine shop can fix it, or you need a rebuilt head.

Let’s keep the fingers crossed that the whole reason for this spark plug remains seating so tight is not a cross treading.
