Got 1 head off. There are no dowel pins. And the carbon ridge on block seemed a little offset on the end cyl. Seemed to clean up with a little scrubbing. Light color on piston is reflection from light. How long can a motor run with no pins?
The corner head bolt holes the left side of the picture (outboard) should have collars in them, are the stuck in the cylinder head?
not in head. head was able to wiggle sideways when i had bolts out. lifted off easy. dowels are 15mmx12mm
