In the past I've connected a valve to the radiator and pressurized it to 14psi so can investigate while under pressure but not hot. This helped me diagnose my. Water pipe failure. Don't forget the two bolts that go into the water jacket back there, one is in the water pipe flange, the other in the blank off.

Looks like we'll have our work cut out for Saturday.
We can also check compression still. She's never had one. I want to make sure she's running well before I start modding after taking care of all the maintenance issues.

If it was a failing radiator, wouldn't I expect coolant all over? It appeared to be isolated just around the MAF area. No signs of collection or residue in the front of the engine unless the heat vaporized it quickly. I did notice some residue and what appeared to be trace coolant collection alongside the driver side valve cover but isolated towards the rear. Again, probably from whatever leaked in the MAF area.
Apart from the short hose and heater control valve and the hose that connects to, what other places for leaks can I source the coolant too?

Oh, I now see The Forgotten On brought this up already. Anyway, I have seen leaks in this area on a few 928s.

Thanks Bill. Some photos. Perhaps it's leaking under high pressure? If this were the case, just a new gasket I suppose.
One thing I did spot was that the long hose connecting to the heater valve, while still connected, wasn't "seated" fully to the valve and had a quarter inch or so gap. I'm thinking it loosened and popped back and when I turned on the fan/heater that's how it started to smoke because coolant was flowing through it.
But that doesn't explain how I started smelling burning coolant before doing that unless it was leaking already and just full blown after.

Pin pointed as the feeder hose. Tightened it. Start up. No leaks. High-powered run. Leaked. Replacement part on the way from Roger.
Despite the leak still there, not bad of a day though. Damn Fraggle's car is fast!!! Got to ride that crazy S4. Hope to get mine and Brett's like that one day.
