Every picture tells a story

Here is the blown head gasket. Note the missing piece of metal between cylinders 3 and 4 and the soot between the other cylinders.

This is the damage to no. 4 cylinder bore, presumably caused by the piece of metal from the blown gasket. I had a lot of difficulty getting a decent photo of this - it actually looks a lot worse in reality. There is a lot of scoring and aluminium from the piston welded to the surface. No. 3 bore is very similar.

And this is what it did to the pistons. The top two are from cylinders 1 and 2 and are how they should look in a well used but healthy engine. The bottom two from the cylinders either side of the blown gasket are ruined - the aluminium of the pistons has melted and welded itself to the steel piston rings.

Here is what I think caused the gasket to blow. What you're looking at is a calibrated straight-edge sat on top of the block with a light behind it. If the block was truly flat you wouldn't be able to see any light between the two.

Now for a scenery chaser - Fenchurch parked up near Malin Head, the most northerly point of Ireland.
