Well cracking day out at Essex Off Road, even better I made it home under my own power for once.
Was a nice collection of trucks down there today, think i'll be there to watch the punch hunt in November.

Ok I have a problem! Lol ... I lost a load of water a few months ago out of the egr sensor plug thing that sits on top of the engine - so that got replaced topped up the water and bled the system and everything was fine. . Done a few miles here there and everywhere! And yesterday drove it 30 miles on dual carriageway and had no heating, engine temp was sitting in middle, it was on the way home I noticed the engine temp rising, so so I stopped and went to add some water and noticed there was water around the filler cap (maybe I need a new one) or could it be a broken thermostat not letting water through so it's causing back pressure and making filler cap valve leak. . Head gasket is ok - what should I do first!
 
Exactly the same symptoms as my old one. We thought air lock, tried bleeding it loads of times and nothing. It was the head gasket
 
I have read that a closed/blocked thermostat would cause back pressure of steam and so consequently water loss, think I'm gonna take thermostat out (and freeze in the winter months)
 
I just had the same with mine. Fitted Dan's 300 engine, new water pump, heater matrix & thermostat but was still over heating.
I'd get a sniff test done or check you don't have air bubbles blowing out your header tank before you start pulling it apart.
I replaced everything on mine, even the head gasket just to make sure but I was lucky mine turned out to be I used the 200 rad but it didn't like it, new rad & it sorted it.

Do the cheap things first
 
He rang me earlier and I explained how to test a thermostat and apparently it doesn't open in a pot of boiling water so that may be the answer.

Fingers crossed. :)

My mate tested the head gasket today that's all ok :) new thermostat fitted but still no hot air, so now I'm gonna change the water pump can hear the bearings in there rattling around! (Still doesn't explain where my waters been going)
