hi Very good test But dry test shows number two cylinder at fault . Using oil into cylinder proves that the compression rings have worn allowing gases to escape but oil rings is ok - ( hence no smoke) with the compression reading still not getting to the same level as the other cylinders you could still have an inlet valve problem. Re-lapping the valves should cure this. If you are intending to remove head turn the head upside down and pour petrol into the recess of the head covering the valve heads. Once valves are covered Go for a coffee - on return and the petrol is now on the floor you found the problem . . Bazza
