Head came off for other reasons, no sign of anything different between any of the bores/piston-crowns or combustion-chambers/valve-faces, but has this gasket leaked?, I can't decide. Had some niggly (hose-connection) coolant leaks after longish sits in traffic and the rad hoses have felt a bit 'too hard' in recent months, but I don't know...? BTW, the flash has added some whitishness/silveriness to the firerings near the centre of each photo. Any thoughts? Ta.
