I switched to colder plugs because that was recommended and I was pretty sure I needed to switch plugs anyway.

You're right, someone was in there doing a lot of stuff, and I have no idea if they k ...

Well it seems I may not have killed the 931 after all. I changed the plugs..they were all wet, but the remaining three seemed to be gas. Which is making me question my observations of the first one. I ...

I pulled one of the plugs out (I needed a metric socket for it, which seems weird, but OK) and...it's wet with oil. I don't know if that is related to the overheating issue or if it was something I ha ...

I think you've nailed it! My cap is not EXACTLY the one shown in the Bosch picture, but close...the terminals are definitely like that.

Now, my distributor has that vacuum advance pod on the side, ...

OK I may be showing some ignorance here. My car is the only 931 I've ever seen closely. The S2 cars with DITC...I thought they had no distributor? Or is it simply that they have no mechanical or vacu ...

I bought some colder plugs and a new set of wires, since when I pulled the boot off of one of the existing plugs, the clip stayed with the plug. Maybe that's not a big deal but I found it alarming and ...

Update (but not much of one):

I replaced the hose, so it no longer leaks. Filled it up started it. It seems to run "fine"...on about 3 cylinders. No coughing and sputtering, it doesn't wa ...

For reference, here are some pictures, first in situ and actively leaking, and second after butchering it during removal:

Things are complicated somewhat on my car by the fact that it's a series 2 with no DITC. Instead, someone has replaced it with a distributor w/ vacuum advance (but no separate vacuum retard) and some ...

I managed to get the hose out. One end is connected to what appears to be a small thermo-switch. No idea what it's switching, but one of the vacuum connections has nothing attached to it, so whatever ...

Hmmm...well I didn't put the water in right away. It was a good hour or two later. So hopefully that's not it.

Also, I did find the (or at least a) leak...the short hose at the back of the block t ...

Update: I was wrong about it not leaking. I just looked at the overflow tank, which I refilled and haven't driven, and it's empty. I filled it again, and coolant is running down my driveway. I can't y ...

So for a while now I've had the symptom of a cooling fan problem (gets hot in stop and go traffic but not on the highway) despite my fans appearing to operate properly. I've had the temp gauge needle ...

If you do that make two and take my money!

It would be possible to custom make a new gate for it from aluminum but with larger ports to flow properly. I may do this for mine if I get time. It doesn ...

Damn, that's disappointing. The ball bearing "gate" system (if I understand it, it's basically a built-in Lindsey Racing-style "boost enhancer") is one reason I wanted this one. Th ...
