Test flight

[Paul Sharp]

My '67 has always leaked some oil. Many others also do. The question is where does it come from? In my case there are some small leaks in the rear engine around the casing at the output end. The engine will get a new O/H before a lot of time goes by, so what is it worth to stop the leaks? If you were to check under a lot of conventional (engines on the wings) twins I be you'd find a good number who have oil under their cowlings, and "wet" if the airplane is flown regularly. A few small leaks that from known sources that aren't serious are not really that uncommon on many models - not just the Skymaster. It's more obvious in the Skymaster, though.

I know the leaks CAN be tracked down and fixed but depending on what the cause is and the amount involved, is it worth it? In my case I'm just going to wait for the overhaul since I know where the minor leaking occurs and it's not a safety problem.
