Yep had no signs of a head gasket issue van was fine it went to a garage due to two injectors failing then all the above has followed on since.
Exactly, presumably heater worked fine etc. A slow head gasket seepage putting combustion gas into the cooling system will build up in the highest point which is the heater matrix, this is why one of the first signs of coolant issues a customer notices is when the heater stops working. So fixing the heater and not the cause of why the heater wasn't working is not the solution.

I replaced the heater as they didnt want to remove all dashboard. Its booked in to another garage on friday so will see what they outcome is with this one.

With head gone would i be able to drive 400+ miles in one day with no heating and temp gauage at middle and then have managed to do a further 700 miles since the day heating stopped working?

Thanks for all the help. Will give a update once i know more
That would depend on the degree of leak /seepage.
As I said previously doing a proper leak test can prove conclusively one way or another.
With a slow leak, you could remove the head and see nothing obviously wrong, but as I mentioned with the engine locked up at TDC on the firing stroke and testing like that on each cylinder with compressed air via the injector or heater plug adaptor, I have seen a leak so slow that with the air pressure on and the coolant filled to the brim with the lid off gradually the coolant rises and starts to overflow from the header tank, when you are talking about that slow a leak it could take some time to build up in the heater matrix to the point it stops working.
Once it builds up to a degree in the top of the cylinder head the heat generated will quickly turn that to steam and force the water from the coolant tank. Another point is when it does that the local hot spot caused can easily distort the cylinder head so machining is important and in some cases crack testing. Also the cylinder block needs to be tested for perfect flatness or a good cylinder head with even a good gasket correctly torqued down will still fail.

Well if you two @bugsymike @jackwhoo ever passing boston linconshire i will make sure i have the kettle on to say thanks.
The last time I was in Boston was in the early 1970s when my first wife competed in the Boston to Lincoln Rowing Marathon, I think it was 32 miles, they row so far on the river then lift the skiff out and put it in the canal to do the rest of the race, or maybe the other way around. I used to think the ten mile ones I did were hard enough, however I then drove about 18 of us back in a rented van all the way back to Torbay with the people who were meant to be reading the map (pre GPS days) either very drunk or fast asleep.
