Hello. I did an oil change today and over torqued the oil filter cover thread. Upon backing out the bolt I noticed there was a loose spring coiled around the bolt??? I'm assuming the previous owner stripped the threads and threw a spring in there to snug it up? Now I'm not sure what to do. I applied loctite and was able to snug it by hand, but obviously want a more permanent solution. Should I use a helicoil? Is this something I should take to a shop to get done? Would a longer bolt work? This is on a 2012 ktm 500 exc. Any help appreciated. Thx!
