Ok so picked up an 81 diesel caddy. PO Said wouldn't start and he blew the head gasket. Well I jumped the glow plugs and pulled the cold start and she grumbled to life.
It was over heating but the issue was no coolant flow due to clogged rad. So now it doesn't overheat, but the upper rad hose gets really pressurized! So I suspect the head gasket it pushing pressure into the system, but I'm not 100% sure
I need some input. There is no burning of coolant or mixing of coolant and oil.
They all get pressure in them when hot. If the bottle builds pressure when started completely cold you have problems.

yea... Pressure after half a minute = bad. Pressure after the engine is hot = normal.
