Had a bad day today. Decided to install my Scott stainless oil filter since my oil is due to be changed soon anyway. When I removed the lower filter cover bolt, the threads were boogered. This is the second time I have taken it out and the first time I have noticed the issue. I pulled a tap and die and fixed them but decided to install a ball bearing like Gray posted in the prevention thread. My threads were not messed up to bad so I figured the hardest part was going to be finding a ball bearing. After about an hour of searching, I finally found something in the shop with a bearing the right size and retrieved it. After meticulously covering all of the holes and sticking a q tip in the drain hole, I drilled a hole that would allow the ball to countersink with out falling through and staked it. All was well, until I removed the q tip. The stick came out, leaving the cotton in the threaded hole with no way to get to the back side. I tried screws, drill bits, and finally an EZ out. I got about half of it with the other half no where to be found. I flushed the bottom end with a whole can of brake cleaner but never got any cotton to come out of the drain. I buttoned it back up and disconnected the spark plug until I can figure out what to do.
