I've taken the exhaust off and tried it on the off chance it was clogged - same result.

Leak tested the head with coloured water and determined there is no blowby occurring at the valves as the fluid remained constant for 15 mins and towel underneathshowed no coloured water.

No scoring or abrasions on the cylinder and the head gasket is still in ood condition.
