I have done some research regarding getting oil to the wrist pins. Dry sump, full scrapers, sump lower than crank etc etc. New pistons now have dual pin oilers in pistons. Aluminum Rods. Coated pins is a option, however at 75.00 each I'm sure that my thoughts and I see some aftermarket rod manufactures have notches on the sides for this very thing. My research reveals that notching a small groove ( A Cosworth Notch) in the upper b/e section of the con-rods should work. Has any body tried this and where would be best position: i.e. 1 notch as a small vee at the 12 o'clock so it sprays up the rod so to speak, or 2 notches say at the 10 and 2 o'clock position. I presume as 2 rods share the same crank pin it would be best to fit these at the side of rods at the crank radius rather than where the 2 rods are next to each other?
