Oil baffles

[Ian Williams]

In my experience with good bores, rings, valves and guide's sevens do not burn very much oil at, all certainly significantly less than a pint every 300! Some engines might leak this amount of oil but properly assembled most leaks can be stemmed to little more than the occasional drip

Edit, I should add that the first engine I built did smoke after new rings, it was the last engine that I used oil baffles on! it was rebuilt again without them and used little oil until i broke the crank.
