Hi all,
Happy new Year to you all.
Got a 98(S)Reg TD5 thats overheating when i go above 60 miles per hour. Also when it starts to over heat i lose power..
Is this the head gasket going ????? I put the heater on full to get the temperature down and the power comes back
Please help.

could be but id check coolant level ensuring you undo bleed screw in top hose ,check rad is hot all over core surface ,incorrect temp(low coolant etc)at temp sender can cause power loss , check thermostat and system for leaks

Thanks very much for the info. Will go check that now.
One thing i forgot to mention is that first thing in the morning the cooling system is still pressurised. Even when cold. Is this normal???. Also had water blowing out the bleed screw on the top hose when its hot and pressurised.???

maintaining its pressure wouldnt be a bad thing but bleed screw shouldnt leak ,cap should blow off excess pressure ,water pump ,rad its important apart from leaks it all gets hot ,cold parts arent cooling engine ,thermostat if after that you feel head gasket get the coolant combustion gas check

Just bled system but radiator is cold so its looking like a thermostat prob.
great news hopefully.
Thanks again.
