After last week exhaust problems, smoker began to operate as it should . I have increased oil flow and directed it directly to inner exhaust tube exit. It works great. With normal aerobatic figures (loops, rolls, cuban 8, rolling turns,...) the flow of oil fumes does not interact with plane surfaces. Unfortunately, with stall spins, hammerheads, .., plane goes directly in its oil fumes which makes a very thin but unwanted layer of condensed oil through all the plane surface. Fortunately 2K colour holds. My recommendation is to make a very efficient covers for all open plane parts (cockpit, tail wheel opening, rudder cover, ...) or better don't do those type of aerobatic figures with smoker [:@]
