Cheers guys, I have the worst and best day ever. As earlier today I filled up my engin with water, thinking I was filling the cooling system. What a tube. Switched a coolant pipe and breather pipe under the air inlet.

Was there wondering where all the water was going and hearing strange gurgling nosies from the oil filler portAfter checking the dip stick, bugger thats a lot of oil all of a sudden.

There was water everywhere, turbo, intercooler pipe. FOOOOk me, was in a flat spin for a while. back stripped everrything and found the offending mistake.

Two complete oil changes later, all good,

Every days a school day.
