Bob, I've have seen people use the hose that goes up and over the cylinders, then down, behind the engine, to the bottom of cowl. This causes the first part of the hose to be uphill. That may help some. I've seen people install an oil/air separator and that can help some. If one of those is enough, that's nice. I've seen oil come out of a Coupe O-200 engine installation so fast that caused a forced/precautionary landing in a field (successful) because of loss of oil pressure. It may be that the O-200 splashes oil more vigerously inside the crankcase. This last instance was ONLY solved by adding the breather-elbow extension. The extension is a tube that gets soldered (silver-solder?) to the crankcase side of the breather-elbow and acts as a pipe sticking a certain fraction of an inch inside the crank-case. The breather-elbow extension works, it seems, because oil is splashed around the inside of the crankcase. Since there's always air-flow out the breather, it'll suck oil from the case walls right along with the air. The extension makes the inlet suck air that's not right along the crankcase wall. The oil on the walls seems not to go along. This seems to put a firm and immediate stop to the oil/breather-tube problem. I think I heard this elbow extension was a standard part on a later Coupe engine (?C-90?) for a while. It can be fabricated by someone with proper skill. I would make very xxxxx sure the mechanic attaching the extension knows what he's doing since I wouldn't want even a short aluminum tube bouncing around inside my engine. I have seen one instance (cited above) where this was the only thing that made much difference to the problem and this solved it completely. I heard of some other instances where this solve the person's problem. Again, I ain't a mechanic and my memories of this are 8-10 years old. Is there someone out there who can give exact and specific info on how to buy/fabricate a breather-elbow extension?
