I have posted a question on the FBH glow plug thread re is there a valve in the FBH system which diverts the water when the engine is not running.

Having had a look on Microcat i think i have found it.

in the car It seems however to be buried at the back of the engine bay. Has anyone had a go at changing one of these as it looks like it could be quite tricky. I am pretty sure its scoobied as it is what is making the graunching noise when i fire up the FBH, i put a feeler rod to it and you can sense the vibrations and stuckness.

I presume you can get to it from under the car.

Im going to try and get the dealer to sort it, however i am prepared to have to fight it out. There is nothing that can't be fixed with a hammer😜😜
