Buddy of mine with the new K24Z7 said he took it off the lot and was redlining for first 500 miles every shift. In which he went through 2-3 qrts of oil. He said after the hard break in it stopped :shrug: so im assuming they used smaller piston rings and they need more time/heat to get to proper size ?
