Well my second to last oil change I noticed it was time to replace my oil pan bolt's washer. Bought one, put it on, torqued it. I noticed an oil drip (the size of a toonie) under my bike after riding it for the day. I figured I didn't torque it enough and left it be as I was doing my winter oil change fairly soon.
Fast forward to now. I've winterized my bike, and removed all fairings to try and locate this weeping leak. Around the drain plug it's wet, but above the drain plug it's soaked on one side of my oil pan. I wipe it down, then nothing for a week. Move it a few feet to let the front tire sit in a different spot, then the next morning I can see it has been sweating oil.
Is it likely my oil pan gasket?? Any tips on confirming this? It's strange it wont leak, then one night out of nowhere it leaks (even if I hadn't moved the bike). Am I able to use those UV sensitive packets that you can use on car engines?
