I just had to post this because I was so amazed. I have an L225 that has a steady stream of blue smoke when running at top speed. It wasn't a thick or heavy smoke, just a light constant stream of it. You could definatly smell the oil in it. Just for grins, I put a bottle of Rislone compression repair with ring seal in it and was amazed that the smoking completely stopped immediatly. I mean from the moment I started it up. I know it didn't fix the original problem, but it kept me from having to deal with it right now. Anyone else have success with this product?
