Well, it may be all over for me and the RC. After finally getting it running on the Motec, albeit a little down on expected power, I really felt I was getting somewhere near happy with it, and was looking forward to a sustained period of driving and enjoying it.
However, on my home recently I had my foot to the floor to get some dodgy chav off my boot lid in a Metro Turbo when I noticed the temperature gague start to creep above normal. I immediatly backed off and pulled over to let the Metro past (not happy about that at all I can tell you), then tried again to be sure, and it did indeed start overheating again. :'(
I thought the loss of water I had been experiencing was a dodgy looking rad cap, but this has all but confirmed my worst fears of a cracked block. It will be going back to Smithy's for a diagnosis to be sure as soon as I can arrange to drop it off there, but if it is a cracked block it will not be getting fixed as I can't take any more outlay.
I will post up if it's definately being broken and have a very long list of parts for sale, most with few miles on them.
There's a small chance it may be something like a head stud come loose, but it's unlikely. Time will tell, but it's not looking good.
