So, have the SRX motor Im working with, and noticed mag and center exhaust ports look your typical dark oily color, but the PTO looks totally different.
Let me know everyone's thoughts.

Looks like mine did last time the o-ring on the head gave up. Just enough coolant to wash the piston, head and exhaust but not enough to damage. O-ring looked perfect but was defective and an oem part
 
So, the pics are from when I tore it apart and replaced the o rings. However, did not look as though the other orings were leaking, but looks like the piston tells another story.
Starting to wonder if the cylinder is cracked.
Sled only has like 2500 miles or less.
