To be honest, I'm not even sure if anything fell in, and if it was It may have been a bit bigger than a grain of sand. The only reason I say is because when I went to put the plug back in, it felt a little gritty getting towards the end of the threads. I pulled it out not wanting to force it, and inspected the plug. There was a tiny piece of what looked like sand or something on the arm of the plug. I hit the pug with carb cleaner and compressed air, put some wd 40 on the threads and it went in without issue. In just concerned.
thanks for replying by the way.
