I just replaced the head gaskets, risers, oil pump, water pump, lifters and and anything else that was not looking good, as I have a 2003 Disco 2 (176K). I also installed a new radiator and thermostat.
The only problem I am having is that after running about 15 minutes it starts to over heat. The top hoses start to pressurize a-lot. I started out bleeding it several times as there was air in the system as expected, but now I have no leaks and I have just over 2 gallons of coolant in it and its over heating, have you ran in to this before? could it be the new thermostat that is getting stuck in the closed position?
