Thread: White smoke from breather and oil drops formed

If you can get access to a bore scope camera that will fit in through the spark plug hole (check rental places), you can determine wether the cylinder is glazed or scored. If the cylinder is glazed the BonAmie trick will break the glaze and allow the rings to seat. If the cylinder is scored, you probably have some broken rings and a tear down is in order.

An easy way to introduce the Bon Ami cleanser is to put a couple of teaspoons in a spray bottle, fill with water and shake it well to mix in the powder. Start the engine, work the throttle with one hand and spray into the carb intake with the other. Gives an even distribution and leaves very little residue behind. This is just the way I've seen/heard it done in the past, and it works.
