I ran at the Airtronics race last weekend and blew 2 glow plugs in the main. After checking the conrod, we discovered it has a little play and needs to be replaced. We measured the pin on the crank and it was within specs just in case it was worn.

What would cause my bearing to go out so fast? 2 $100+ bearing in less than 1 year is a pretty steep price to pay. I decided to just order the complete rebuild kit. Anyone have any ideas what would cause this?
