Bob Culver was spot on (unfortunately !)
When I managed to get head off, cylinders 1 and 4 looked as you would expect them (bored to +30, no significant wear lip at top of cylinder)
HOWEVER, when i examined 2 and 3 they both showed significant damage about one third way down length of cyclinder. (see attached photo)
I guess this is how the water was entering the combustion chamber.
I have pulled the engine out this afternoon, and all I need now.....is a replacement block, anyone any ideas? (I assume the current block is scrap....I wouldnt have thoughtanything can be done to rectify it !)
Thank you Bob, without you suggesting the possibility of rusting through of cylinders, I wouldnt have thought to look for this possibility and may have replaced the head...........and still had the same problem.
I could not find the original post you mentioned regarding appearance of cylinders, perhaps you could point me to it?
