Can you help with diagnosing headgasket prob, pix included
As title, have taken the head off my 1.8 zetec, as their was oil in the coolant bottle, and varied / intermittant hot air from the blower.
From the pix, can anyone see any probs that would suggest the headgasket has gone??
And / or any other visable probs
seems to have quite a lot of carbon build up on the top of the pistons
apologise for the not so good pix
Thanks in advance

Yeh that was my next approach
just assumed it to be the head gasket, as you do, dont really fancy stripping the bottom end down now too, more expence unfort

The carbon should be evenly deposited over the whole piston, when the headgasket lets in water, it superheats to way more than 100C so cleans fantastically well,(getting rid of all the carbon) as it appears to have done on the edges of no 2 and 3 which from the piccies look perectly clean, take the head and put on a bench, and have a GOOD look for a tiny fisure crack, very normal on zetec and will skim out, h/g are easy on these as well.

is it worth just getting the head skimmed and pressure tested as a matter of course then??
i was hoping to see more evidence of a fooked head gasket thats what confused me, really dont want it to be the block itself at fault

Not going to be the block, yes without a doubt the head will need skim, but stacks of meat on these, most likely cause was not done right in first place.
You won't see evidence of a blown gasket when it is water leaking in as it just squeezes past the gasket as opposed to burning it with comnbustion gasses when most go like that.
I had a mondy with a brand new 12,000 old engine rebuilt by me, and auto gearbox sold to my dad and told him NOT to top expansion tank to FULL TO THE BRIM, when I saw he had, he would not listen, less than 100 miles later I was doing the head gasket for him!!, as this popped the gasket due to pressure.
