[QUOTE="trailblazer, post: 505114, member: 20738"] Evenslower: I have used both oem and wiseco. The first oem lasted about 2300 miles. Still within tolerance(piston/cylinder clearance), however, it had the start of a hairline crack across the intake skirt. Caught it just in time. Used a wiseco for 1500 miles. Piston worn enough to be out of tolerance for piston/cylinder clearance;and, the ring end gap was worn beyond tolerance too. Installed a new oem piston after the wiseco. will chanage rings at 1800 miles this time. perhaps piston won't start a crack in the skirt? Either set up will work. Put in a new wiseco every 1500 miles and you should be fine. The oem will last much longer if you change rings when required-but, costs almost twice what the wiseco does.
