Ive had a fair few problem with my coolant system after I put a Branch through the Rad, greenlaning. Ive had constant problems with overheating and waterleaks, Ive replaced a few pipes that burst, Ive checked the thermostat that stoped the overheating.

Now I'm lossing water with no visable leaks. On restart from hot very poor tickover. It sounds like it missing sometime but does really lose power. I'm Guessing at head gaskit. Can anyone give a conformation or another ideas?

Oh and is there anything I should now if Im going to tackle it myself.
