I changed my oil for the first time on my 2012 yz450f and the oil filter fell out into the bucket while I was taking the cover off. I threw the bucket away and didn't check if the was a spring inside the filter. I didn't see if there was a spring in it the filter and if the is no spring which way does the filter go back in. 1. Is there a spring? 2. What way dose the filter go in, does it go in with the hole in the filter towards the motor and away from the cover?
