Think I've found a better solution. The plastic tabs were a bit dodgy looking which I think let the bleed valve escape so with nothing to lose I ran an M12 tap through it and fitted a short bolt with an o-ring and it seems to have sealed perfectly. Runs slightly cooler than before (around 85 on the gauge under normal driving conditions) and temperature stays way more stable than it's ever been in the four years I've owned the car. Hasn't lost any water either which it always used to do despite never having shown any other head gasket failure signs. Oil and water have never mixed, temp gauge not been allowed over 100 but every so often it would happily drink a couple of litres of coolant. Think this may have been an issue the full time.
Really need to stop it leaking so much diesel everywhere it's parked now.
