I made a vain attempt at using compressed air through a compression tester adapter installed into the cylinders i was not able to blow anything out which leads me to believe that whatever got into the cylinder fell further in and became wedged between a valve and seat. This would mean all the pressure ofthe valve spring is holding it in place. So for now the plan is to remove the headsand inspect the pistons cylinder walls and combustion chambers and obviously the obstruction should stick out like a sore thumb wish me luck
