Ok, here were the symptoms:

Rapid coolant loss
Huge plooms of white smoke from exhaust
misfire on start up gradually going away

Assumed head gasket but have stripped it down and it looks as new, all the plugs are fowled up so can't tell which one is wet.

So, it must be either a cracked head or liner? From the symptoms which one is more likely?

Thanks

No idea, but since you have it stripped down I would have thought either problem would be pretty obvious.

Are any of the cylinder/s noticably cleaner than the others(less carbon deposits) ? have you examined the headgaskets looking for burn marks on the fire ring area(the metal ring that circles the bore) ?

Bear in mind that the signs of HGF might not be that obvious, just because you can't see any evidence doesn't mean it was all good. Might be worth checking for flatness and reassembling with new gaskets, then do a cooling system pressure test.

[/quote]Thats true enough,but if it had steam pouring from the exhaust then i would expect some decoking on that cylinder however slight,and possibly staining on that cylinder bore where the coolant as stained the bore(not always present though)starting with a misfire shows that possibly that cylinder was taking in enough coolant to kill combustion on start up,of course that maybe relted to a dodgy plug/ht lead though biggrin

Sorry to say that these are the exact symptoms I had with my Chim and it was a slipped liner.

Is something like a slipped liner obvious to the eye? The block and heads are fairly new and look new too, no marks or anything anywhere!

If its a new engine do you have std liners or top hats. Just compare all the liners and see if one has dropped lower than the rest.

Also might be worth checking each liner with the piston down, to check for hair line cracks.

When they took the heads off mine they couldn't initially tell if a liner had slipped. Once the block was pressure tested it showed up.
