As title states just got a 400ex and there are aluminum shavings in the oil, what's the most likely part getting destroyed?

Runs completely fine, no knock or abnormal valve tick, it even has full power on pulls

Went full sent today, beat the crap out of it for 8 hours straight in 90 degree heat and by the end of the day started to puff blue smoke, gonna send it with the ebay $30 rebuild kit and probably get bigger oil cooler with a fan
