Sorry for the delay but I've had a couple of late nights stripping this engine down and then had guests over the weekend!

Below are the relative compression captures both cold and hot and you can definitely see the drop in relation with temperature. James' WPS confirmed the actual pressure readings the next night!

COLD


HOT


I set about stripping the engine down and revealed a burnt & cracked exhaust valve in cylinder 2!!



Some of the WPS captures we took didn't make much sense so we will redo them when this is reassembled and do some comparisons to hopefully shed some light!

Thanks again for everybody's help
