Hi All
Just wondered if anyone has any advice on what else to replace during rebuild if head OK when tested and my problem was just a head gasket?

Looking to get new rad flush cooling and poss new water pump thermostat
Will do all belts .hoses injectors if required filters and oil
Glow plugs are they a must??

Any one come across anything that could be a future problem if not done now??

Cheers Doffer
