I have C-16 #42 serial 086, and (fortunately) the older style engines don't have front brakes, so there's no transfer of the oil to the railheads, and I won't have Clark chasing me with cutters if I ever get to his place! After a run, the cylinders and pilot truck are covered in steam oil, as is the boiler. These engines definitely spit it out. However, I'm told the small tube/blastpipe in the smokebox is the resonater for the "chuff", so removing it may have other consequences. I like the idea of restricting the oil flow - but it is difficult to know 'how much is enough'. Maybe someone who knows what he is doing could experiment and give us some ideas? Pete
