Sorry, a little patience please. I've had some family issues over the past week, didn't mean to ignore. Will look over the pics on my computer when I get home, hard to tell when viewing on my small phone.

I can't tell much from the pic's
Better would be a pic of the Piston Skirt.
The Dome of the Piston doesn't tell mush other than what appears to be normal carbon.
And a better shot of the Cylinder Wall itself. any Factory Honing marks Left?
Can you Very Carefully remove the Top Ring and show us a Ring End Gap in the Cylinder?

The piston skirt would be the side of the piston where the rings go, to the bottom of the piston, as for the cylinder wall would be the jug that the piston sits in when it is put together, just try to get clear pictures of the walls to see if any scratches, or anything. As for the ring gap, take the ring that was on the top set of the piston, put it carefully into the jug and make sure it is even, then take a picture showing what the gap in the end of the ring is. That is what they are looking for.

Can u explain in more detail were these are I need to see the Thrust Sides of the Piston to show me the wear it has. The thrust sides are the side's  degrees to the Wristpin. Also a Shot of the Cylinder Bore will give me indication of Cylinder wear. The Factory Honing will look like a Cross Hatch/ Criss Cross Pattern in the Cylinder. Carefully Remove the Top Ring and Slide it in the Bore, Square it up with the top of the piston upside down. The Ring Gap can be measured with a feeler gauge. Rule "O" Thumb, .003-.004 Gap Per inch of Bore. This will or show both Ring and or Cylinder wear. Tryin here Bro! |

I see to the upper right of the Exh. stud a hole, on mine as it Appears on yours this is a as Cast Flashing over a Air Flow coolant hole, Air is supposed to flow thru there, around your Hot Exhaust Port and comes out thru the top of the Cumbustion Chamber. I hope my verbiage explains. I have actually Cleared this Flashing Away to permit more air in to Cool this Area Better. If that Hole Goes anywhere but what i said it would go directly to the Cylinder Stud Hole. It is close to the Exhaust Port, but if it broke thru you would only have Raw Exhaust coming from it and it would be Black from that gas escaping. I'm most sure this is not the case as Im holding a Cylinder Head in my hands as I type this. |
