Overheating damage

[HappyCamper]

Hi Guys,
Over Christmas I travelled 250 miles to Essex in my 1600 normally aspirated diesel. A few days later on the way home, I'd covered around 180 miles, the heater started blowing cold. The hose from the head to the heater had parted where it reduces. The AA sent a local garage out and he presumed it was just an old hose that had failed. He folded over the end of each hose and filled it up with water. All seemed okay for another 30 miles then it was overheating again. It had split the hose from the water pump. I managed to cut it and reattach, filled it up with water again, but only managed around 1 mile before the large 4 brach hose split wide open, about a 4 inch tear. Got the van relayed home, but it was difficult to start to get it on and off the transporter. I haven't had the heart to start looking at it yet. Pressume the coolant system is being pressurised and not sure what damage has been done. Is a blown head gasket the only reason for exess pressure.  Thanks.

If the engine won't start, the symptoms do seem to indicate some serious damage like head gasket failure. 
I have a CS 1.6NA diesel engine here, which is for sale. It's a Vege recon which has done approx 20K miles and was working fine when I removed it to upgrade to a 1.9 engine. It has a slight oil leak from one of the blanking plugs at the front of the cylinder head, but that doesn't affect its operation. It has always been stored in a dry, clean conditions, with the injection pump full of lub oil.
Once you know what the problem is, if you are interested in my engine, please PM me, and we can discuss.

If you find out what the problem is, i'd love to know. Had two hoses and the waterpump fail on my CS too this year. Still hoping it isn't the headgasket...

I've started by replacing all coolant hoses, including the heater ones under the dashboard. They definately were old. Has worked so far.

Also, the dalek cap should prevent too much pressure building up, right?

I'll hopefully get to look at it next week. Maybe do a pressure test on the cylinders first. Thanks
