CATS and clutches. What are the chances the 34-year cat is still flowing well? When I get her on the rack and inspect the clutch how can I tell if I have the original clutch?

If the clutch works why are you so anxious to spend something like 15 hours replacing it? If it is original and still works just use it. I am all for preventative maintenance, but the clutch on a 944....

I've been told the original clutches have a polymer part that can break with age and cause damage. If this is not so then great!!! All I need is steering, that manual rack is being ordered right now, and shocks from Oriellys.

Heater not working. I'm sure water is flowing through the core, just the flapper isn't moving. Any way to move it manually?

Odds are that, at 34 years and 166k miles, that original rubber clutch broke years ago. Unless someone replaced it with another one (which might have also broken since then), you should be fine. Unless I knew it had one and it was old, I wouldn't even give it a second thought.

As for the heater valve, yes, you can manually move it although you may have to disconnect the actuator arm to keep the system from trying to reset it if you want to make sure it works. It's pretty easy to do (albeit a bit of a reach through the stuff back there). You can google what the heater valve looks like and that should be easy to find or I can post a picture when I get home.

There is a clip that often breaks on these things but I think that defaults to turning the heater on (as best as I can remember, anyway...).

Thank you. I will inspect it soon. I've seen a video with an original clutch and pressure-plate and I hope I'll recognize a new one.

Remove the old catalytic converter? It's huge, old, and I'm sure doesn't flow as well as it used to.

Why? Mine is 37 years old and still works great. Don't assume just because it's old, it's no good.

The only way to know is to inspect it and that requires removal and at that point, I'll just replace with a lighter-weight modern unit or a test pipe.
Have y'all forgotten all the complaints about Euro cars with poorly engineered smog controls well into the 90s? The system on our car is an afterthought compromise.

Not convinced - Porsche engineered their cars as a whole system, other than lighter weight, not sure that you would receive any real-world performance improvement.

So did GM and Ford, but Porsche is the one that almost went bankrupt and brought Toyota in to salvage the company as the 924/44/68 series was ending its life. The domestics didn't have a monopoly on bean counters. Want some more kool aid?

I found the valve and disconnected the vacuum operated actuator arm and now I get just a tickle of heat from the foot vents. How can I move the air flapper? The sliding HVAC controls don't seem to be connected to anything.

Those controls have a very loose feeling compared to other cars. Unfortunately, I don't know enough about the inner workings of the HVAC to be much use here. Maybe check to see that all of the HVAC vacuum lines are connected and in good shape? Again, that's outside of what I have messed with but it would be my first step.
