Headgasket Help
Replaced my rad with alloy one,new hoses and rad cap
Filled the coolant from the pipe on the turbo like i read on here seemed to have pushed all the air out went for hard run come back the bottom and rop rad hose are rock hard,Let it cool down took cap of bit of air in system topped coolant up again and went for test run come back and its pushed water past the top rad hose clip enough tho its tight
Is this headgasket or really bad airlock cause im getting no water in my over flow bottle

Could be either. Drain the coolant and refill SLOWLY as before, ensuring the heater is on HOT and you don't allow it to gulp.
Takes about 20 minutes to fill if done properly.
Set engine running, leave cap off, mop up or top up as required until fans kick in.
Replace cap, go for a drive round block, allow to cool, remove cap and inspect level.
IF it still does it, get a sniff test done.
Might be worth replacing the thermostat and it's gasket while it's drained, unless you have already done it recently?

It's worth checking the small bore pipe leading to the header tank from the rad to make sure it's pushing water through it at idle. It's how it bleeds in the first place. With the rad cap off, you should see water bubbling through it. There is a one way valve in the tank.
Yes i replaced therostat last week will give it other go tonight has every thing seems ok no misfire,no water in the oil,no smoke just keeps finding weakest hose to spit water out past
