That's right. Two of my piston liners moved. Everyone is saying how awful and terrible it is and that my life will never be the same, but for the life of me I can't figure out how so. The Volvo manual states and I quote: "Caution! Make sure the cylinder heads do not separate from the seals at the lower seat. If this happens, coolant can flow into the crankcase necessitating a complete engine tear-down and cleaning." When you remove the head, under normal circumstances there would be coolant in the block, which could run into the crank case if they moved. In my case, the block is bone dry, so there was nothing to fall in. I suppose it's a possibility that coolant could leak beneath it when the head is on, but it seems very remote. The amount of pressure that will be placed on them from the top that should be more than enough to seal them back. And the seals are attached to the bottom of the liner and cannot move or shift, so there's no off-kilter seals to worry about. Let's say for arguments sake that I have to strip it down, take out the pistons and check the liners. Well, you have the same problem as before. YOU MOVED THE LINERS... and this time you took them all the way out. Who's to say when you put them back you got them down correctly? See my point, or am I blowing smoke?
