Quick update.
Got the head off which looks ok but the cam chain is a bit loose, got a spare head and it's much tighter on that.
The head gasket has definately burnt out between cylinders 3 & 4. Could this be the only culprit or should I look intot eh pistons while I'm at it?
Gonna put some pics up in next couple of days, cylinder 4 piston is worrying me as a I can see more of the piston ring than on the others.
Think I was lucky with the exhaust manifolt too as it wasn't too difficult to get off.
