Hey, ive been cleaning this and that and pulling stuff apart to inspect and have got to the sump cover part, i pulled that off to clean the sludge and a good oil change and i commented to a mate that i could see all the way up thru the engine, he had a look under there and said my rover may of had work done to it in the past, i said how can you tell, he replied that theirs a dot on the piston arms, then he said, hang on theirs 2 dots, then he looked puzzled. Anyone know what hes on about? yellow dots mean replaced pistons?
