I'd say you have a small fracture in one of the heads.

For your next move Jonathan I would recommend another attempt at bleeding but this time following MG Rover's procedure which I have reproduced here. Note that the expansion tank must be raised and the bleed screw never opened whilst the engine is running. Simon

Hardly likely. I know for a fact that the head was inspected during a previous service – many moons ago, admittedly – and that the valve cap cover gasket was replaced. There are no visible leaks around that, which would mean then that I'd have a valve cap full of coolant.

I very much regret to say that I don't Phil, but I'm pleased to be reminded that I was of some assistance! I'm sure that Jonathan will note your experience. It never ceases to amaze me what can be discovered by just looking. The tiniest clue can often lead to a hitherto hidden defect.

If it doesn't cool the engine and doesn't heat the interior, even when there's coolant in the expansion tank, then there mustbe an air lock imho. Yes. Mind you, that one was pretty self-explanatory though. For all its drawbacks, the kind of "three-position" temp gauge at least shows quite clearly when the temperature is at what could be considered normal. And I use the onboard diagnostics real-time thermometer all the time now. It's a bummer to get to, but it's worth the trouble. |

There's indeed a lot of plastic in there, not to mention the clips, viz. plenty of stuff that can go bad over the years.

That's an excellent quote Jonathan. Simon
