The age and mileage of the 986 "fleet" continues to increase each year. Thus, a lot of engines are reaching the end of their useful life.

This is normal, expected and it will get worse as the fleet continues to age and add mileage.

It worries me a lot for future resell values and availability of replacement engines.

Just like any aging car, engines need to be rebuilt/replaced. Just part of the game unfortunately. Availability of parts etc will not be a problem IMO. A: Porsche makes every part for the whole fleet, there is at least that. And, there is a robust aftermarket for Porsche as a whole, and many specialists. Don't think keep these cars in good running condition will be terribly difficult. In terms of cost/value... personal decision. These cars, like all Porsches, will have their day.

AOS and oil cooler replaced.
Now the flushing starts.
When I started the process I noticed that the plug for the air intake was unhooked.
When I finished and started the car, it wouldn't idle unless I unhooked it.
Any ideas?

Uh, that plug is your MAF sensor... not sure how the car is running without throwing codes with it disconnected. Have you ever had a look with a code reader? Something is not right with your overall system. Could be as simple as needing a new MAF, could be a can of worms... probably has nothing to do with your oil issue though... also, please clean that engine while you are there... makes it happy.

Weird...I'll have to dig out the reader.
CEL has never come on.
Car runs fine with it unplugged but stalls if I plug it in.

And yes a complete engine detail is in order.
Want it working correctly first.

first bit of good news.
Took her for a quick 10km to bring her up to temp.
Carefully took it to redline a couple of times....no smoke
Seems to still run strong.
Still got hot because I have no coolant flow.
Other than the obvious..ie pulling the bumper and trying to empty the rads of the gunk, is there anything else is should clean to get it flowing and is there an additive I can use to break down the oil?
