Pretty sure it hasn't got any cracks. I could leave it running for an hour stationary and it wouldn't overheat etc. I was monitoring the temp via the dash and via obd. Cant remember the figures but when it got to the right temp the fan would kick in and bring it down.

I see what you are saying, absolutely fine was on idle 93 degrees 70 kpa no problem at all, just give a ride and problem appear. How I say worth checking cylinders head, no idea why but front looks like a going in 80% cases.

The usual first reaction to this is that the cooling system is pressurising due to a blown head gasket. However, forum reports have shown that coolant ejection is also a result of the application of K-seal. I'm afraid that it's very difficult to eradicate. It's been known for it to collect in the oil cooler and form a physical obstruction. You'll be able to look into this when you begin dismantling for your cambelt change.
