I'm an old harley mechanic, trashed oil pumps aren't that uncommon with shovels & evo's, pretty cut & dried what goes on and with yours there's big red flags as it rarely gets to the pinion gear like that. Rotate the motor to TDC, grab the front rod and see if you can move it up or down any or while holding it straight with no side to side shake and try to twist it, you can you got rod problems, lower end is coming down. Not uncommon for the crank pin to start cratering out when metals been floating around in the oil like I see here. Front rod will tell you, rear shouldn't have any side to side, twist or loose feeling play.
Thanks, I´ll do that.
Is there any play at all allowed in any direction or should everything be absolutely dead in motion when trying to move/wiggle rod?
