Hey Guys,
Was casually driving home this afternoon in the rain thinking about how the Rangey was in it's element, real good pommy weather, running like a dream, overtaking all the Perth drivers doing 30kmph under the speed limit because of the rain, when suddenly the temp spiked right up and I started getting a lot of hot air out of the vents. I pulled over, popped the bonnet, and could see the coolant bubbling in the expansion tank. I've noticed a small amount of coolant vanishing over time and didn't really know where it was coming from, just kept topping it up (Bad move I know, Rule #1 of P38 ownership, Fix it before you stuff it).
Anyhow, topped up the coolant, let it cool down, drove home with no temp issues. Once home I popped the bonnet to have a look around and noticed a hissing noise. I isolated it down to a plate on the bottom of the throttle body that has 2 coolant pipes running to it, one from the inlet manifold and one to the expansion tank. It was hissing and bubbling, not bad but obviously not good. Seems to be a gasket between the plate and the housing that's leaking, see the picture.

So I whip out the old RAVE manual and "flick" through to the cooling section. I find the section on the "Throttle Housing" which explains that hot coolant is fed through the throttle housing to prevent the throttle body from icing up. Now, I understand what icing is, I know vaguely how it's caused, and have done a bit of reading up on it in regards to my Mini's and their SU Carbs. I have NEVER in the 12 years of Mini ownership, 2 of them in Albany, 10 of them in Perth, had an issue with icing. I can't imagine I'm going to have any with the Rangey.
So ultimately, what I want to know is as a bandaid fix, join these two pipes together so they still circulate and put some caps on the throttle body and everything should be peachy???
Cheers,
Keels
