Its happened to me twice and both times I felt like somebody was watching over me those days.
First time I was on the interstate doing bout 75 switching lanes and felt the back shimmy ever so slightly a few seconds later I rev it up to switch lanes again and it really went wild on me so I decided to pull over thinking maybe I had a flat. The thing is when you stop and and shut it off that's when the circulating oil gets loose and wow....you better back the hell up if you know what's good for ya, cause hot oil sure ain't the new lotion for your body
Second time was after an oil change. My carbs over flowed and I needed to change my oil twice so after the first change I thought I'd go a few mins up the road then come back and change the second time. Well, bout 5 miles up the interstate I get ready to take an off ramp and I'm really on it ready to get deep in the lean when holy shit I felt like lil' Nicky for a min the way the back was sliding on me.
My remedy to the blown plug is.....I bought a plug that has the nipple on the end that you plug a hose into to drain your pan. Sure, it takes a little longer for it to drain, but you don't have to remove the plug anymore. I put a lil teflon tape on the threads and a smidge of locktite and it's never moved once and no drips.
