Hi, Can any one suggest why i have a piece of my piston missing, with no damage to the head or piston? i would have thought if a piece this big has broken away in would crash into the valves & piston. I had to remove the head to check for a suspected gasket fault. which there was accross this piston & a water port.
Could this piston have been like this from new? it is a stock motor.
Any advice would be usefull in trying to pinpoint the cause.
Engine was running fine until i noticed the water in the oil & steam comming out of the exaust on cold start
