The "drain holes" on the exhaust are for O2 sensors.
The plug could have been dropped by the mechanic just before he put it in.
He should have checked the plug for damage after droping before he installed it.
These are just guesses on my part,but wish you well on this project.

Well, see, this is what happens when you are unclear about what it means to have the first 911 with a water-cooled engine.
Seriously, good luck with the project. I'm still proud I could swap my own side markers, so I'm in awe of folks like you.

It's alive!!
Massive progress!
Finally got a spare couple of days and the right ecu/immob combo and the starter solenoid started trying to work, which from what people had said meant that the immobiliser headache was over!
The starter was removed and tested - dead. Liberal sprays of WD40 and a few gentle taps with a hammer and it stuttered back to life and eventually it seemed to be fully working.
Once the starter was put back, the engine turned on the key! Very sluggishly at first, but on the second try, it very nearly fired. At that point, I rang my dad as he wanted to witness the first starting. He arrived, turned the key and it spluttered into life!
The n/s bank of cylinders all seemed to be working (with a lot of steam from the exhaust), but the o/s didn't appear to be doing anything. After 5 minutes of idling, I prodded the throttle and it was definitely only running on 3 cylinders. 10 minutes of idling later and a prod of throttle and the o/s exhaust started steaming slightly (by this time, the n/s exhaust was completely clean). More idling and gentle revving and it is now on all six! There is still a bit of steam coming from the o/s exhaust, but that's not really surprising given what it's been through. I think another run up to full temperature (fans all kicked in, everything appeared to do what it is supposed to) will clear that side and we're in business!
My only concern (well, top of the long list!) is that there appears to be a noise not unlike a coin in a washing machine coming from the o/s of the engine. It doesn't seem to be a constant noise and it might be related to the water which is still in the exhaust system, but I was wondering if anyone had any ideas?
Bad weather has stopped play today, but as soon as it stops raining, I'll carry on.
Frankly, I'm amazed (and ridiculously excited!)

You might check the chain tensioners. You can pull the two rear ones fairly easily. Pin the engine at TDC before you remove them. Do a search for "replacing IMS bearing" for instructions.

+1. The fact that the sound isnn't rhythmic suggests something related to exhaust as a possibility (let's hope). If you decide that it's safe to run the engine again, try to isolate the noise via a stethascope, etc. As Pesuazo said, may be a muffler... or a converter - good luck & keep us posted. Interesting project.

Not to cause panic, but could the IMS bearing loose it's grease by sitting in water? Hope that's not the coin in washer sound you are hearing!
Looks like a really clean car (no pun intended)! Hope it works out!

First off great project and nice that the DME/ECU was not damaged. The sound could be a number of things including the IMS impending failure which there are online videos that can be found for sound comparison. I would imagine there are shops that can repair or replace with new engineered IMS bearing if needed. Did you remove all the carpets (foam backing can hold moisture in the foam), seats etc to completely dry off?

If work on the car becomes too much work there is always stripping it down to be a track car. Selling the parts like seats and such can help fund new light weight seats and belts.
Sad to see such a nice car got flooded. Have fun organizing the parts reconditioning the car.
