That head damage wasn't caused by rings as it extends beyond the bore. My guess is it was caused by a twat.

Just the effect of water in combustion chamber over an extended period of time.

What in the hell is that thing? Is that a worm? You must have very different worms on your side of the pond.

I think that someone thought that squirting grease in there would help to un seize ::)

on mine, the rings had smashed their way out of the top of the piston somehow and gotten trapped between the piston and head causing similar dammage, then someone had poped the head off, removed the debris. I went one further and replaced the pisteons but ran a head with very similar dammage. Water doesn't do that to a head, I had an engine where all the cultch casing had literally corroded away, gearbox totally shot, somehow the head was immaculate once a few kilos of thick clay mud were removed from inside the rocker cover. I still think it sensible to source a replacement engine though I have thashed a few years commuting out of 550s with parts that rough.
