RILS Posted August 2, 2006 Report Share Posted August 2, 2006 How can i tell if my piston's are still good. They are black on the top's and look's like there is some wear on the top's. Look for the wear on the sides of the pistons.Scratches grooves exc.Same thing with the cylinders.You need to mic the cylinders for taper and piston to cylinder clearance.Imo if youve wore out a set of rings its time to bore to the next oversize or whatever it takes to clean up the taper in the cylinders.Some may have diffrent opinions but this is mine.
