Have got the heads off now, and it's pretty clear that they were leaking badly. The mating surfaces of the block and the heads are actually very good compared to another one I have seen before, so with a good cleanup and a fresh head gasket, it should be sweet.
Looking at the combustion chamber & pistons however, a couple of the cylinders seem to have a lot of oil in them, and a couple seem to be running lean (pink spark plug?)
Can anyone shed some light on this?
Edit - Seems the black residue on the pistons and heads may just be residue from the coolant etc seeping into the cylinder.
