Thankxxx guys...........Guess I should of been more specefic. What I`m refering to is the oil ring pack staggering/spacing not the ring end gaps. I`ve always set the oil expander gap at one end of the wrist pin then stagger the top and bottom oil rails about 1 1/2 inches on either side of the gap and let er rip. The directions say to put the expander gap at the wrist pin but the show the oil rails on the OPPOSITE side of the piston NOT the same side as I`ve done for years.
