Desperately need help guys, due to go away monday but the cars poorly, had a thermostat fitted last weekend but noticed a leak around the bleed screw, so I put a new bleed screw in but was still leaking, put some PTFE on and it's slowed it down, lad who I use for repairs thinks it's a new radiator job, anyone else got any suggestions before I take a lump hammer to the whole car?

Heres some pics which is what makes me think it's the bleed screw,
