I spent 3hours this afternoon taking the head off of my 2wd sapphire cossie as i had lost water from the header tank into the sump and it started on 3 Cylinders in a morning. I took the head off and the YB0611 head gasket looked like it sealed all round on all surfaces, didnt look like it had failed at all, so I wanted to know where else on the engine might oil and water mix?
Could the turbo waterways crack (its a brand new turbo, done less than 100miles on it), there is an oil stain at the bottom of the housing though which is odd?? or could the oil modine behind the oil filter be knackered or?? Any ideas. I ran out of daylight but have yet to turn the pistons over and check the bores for cracks, the pistons have no rusty water stains or such like, the combustion chamber was just covered in oil too which is a little worrying too??
