Just noticed a small oil leak and think it’s one of the 1/2”bolts that joins the front of the block to the rear. Love to post a picture but no idea how to on this forum. I also noticed what looks like a slice from a circular saw along the seam between the block halves... REAL strange. I’d greatly appreciate if somebody can email me (sobikes@verizon.net), letting me send you the pics for inclusion here.
