Motors wear out over time. If your like me you rev like crazy often just b/c. On my high mileage swapped hatch i need everything from the ground up - rings, valve seals, valve guides. ON top of that my OE seals i changed a while back are starting to leak again. Got years of service from this motor, can't complain. Original rings, valve seals etc. when i break it down i'll see how it held up. Mine burns oil around 4k and up / road racing (80+ MPH) . Normal driving it consumes very little if any. GL
