please excuse the poorly drawn diagram, but as you can see there is no way (unless your piston is in pieces) that it will hit the plug. it may be out of time and hitting valves. If this is the case then you will have to replace valves because they will be bent. on a side note, if you type like a grown up not a drunk 12 year old it will be easier to comprehend your issue and more people may be inclined to help you. edit: this diagram depicts the piston at TDC.
