Help please

g'day guys cheers for ya replays all have been a help
The motor has no blown head gasket like oil under cap or any bubbles while running and it's not using any fluids other than what was getting spayed over me lol and as for radiator it's old but in ok nick wasn't clogged up with shit or rotten
I've replaced fan and hud it's shroud it in good condition
So today I replaced the radiator cap and the thermostat and yep use guys where right it had the guts taken out it out got it all bk together filled it up with new coolant bleed the air out and let it just run for 10 min and for once it actually idle fine with no misses turned it off waited an hour or two and took the cap off and NO pressure coolant was at correct level
Took it for a drive and it run the best it ever has since I've had it and the temp gauge was about 1/3 bit over drove for about 30ks up pretty hilly roads and it didn't really move got home waited for it to cool Down and popped the cap off again and still no pressure no oil no bubble and good coolant so fingers crossed guys lol

I think it's good by the sound of it. If you don't see any milky residue under the rocker cover oil cap, I would be happy.
Sometime you can see milky residue under the oil cap after shorter drives, when the thermostat's been removed or opens up at a temperature too early(as in my case few weeks ago).
Just to be safe, do a compression test when you get a chance.
