I wouldnt worry about it if your not pressurising coolant lol, if it was head gasket then you would be pressurising coolant. If its a scored bore then f*ck all you can do unless you wanna pull the head, pull the rods/pistons and re-hone. It may not even be a drop in compression though, it could just be a really shitty coincidence with the injectors, or a leaky fireseal, or even a leaky injection line, or maybe even a bit of shit worked its way through the pump to the distributor head or maybe even past that to the delivery valve.... and then all this could be happening to each of the injectors that you test with a little bit more shit working its way through.... endless possibilities.......
Does this stop happening after a long old drive by any chance?
