There also is a baffle inside the draft tube that coalesces oil mist to drop
back into crankcase. I never heard of these going bad, but I suppose they
could. You would see a few drops under tube on ground. The recommended
unofficial method of cleaning a draft tube was to remove it and burn out the
sludge. I never did this so don't know how much intenal damage it does. I
soak them in lacquer thinner or carb cleaner to dissolve sludge.
