- an overheating event (likely WP failure)
- tight factory bearing clearance exacerbated by increased power demand (tune)
- production/manufacturing change/part update
- long factory oil drain intervals

I had my OFHG, OCHG, waterpump, and thermostat all done about 4-5k miles before my motor went. Considering it was done all at once, I am pretty sure the coolant was drained before the OFHG was done. Figured it might just be worth mentioning.
