Anthony; John did give good advice with which I agree. I just delivered a 1945, 415-D to its new owner last month. I added the extension on to the crankcase fitting, and then used the Forney vent tubes which bring the case vent over the top of the engine before going down. (They are available from Lee at Skyport) Instead of locating the discharge end at the opening between the firewall and the bottom engine cowling, I put the discharge right at the edge of the exhaust pipe opening in the cowling, on the upper side of the opening. After 10 hours on the engine, (fresh major overhaul by me) I did not have to wipe a single streak off the belly. I did get a couple of drips out of the tube after shutdown, but by strategically placing the tube in the opening, the drips ended up on the concrete and not in the bottom cowling. FYI, on my Coupe, I ran the vent line through an air oil separator, which drains back into the accessory case on my O-200, before the tube ends up at the opening between the lower cowling and the belly. On my Coupe, I get an oil colored streak on the belly after 10 - 15 hours of flight. Yes, I am considering moving the tube. <g> Lynn Nelsen N99387 52FL __________________________________________________ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ____________________________________________________________ T O P I C A -- Learn More.
