Fred: My hangar partner has a Piper twin with Continental 360s.
He was losing oil from his right engine and after a LOT of trial and error he
and his IA (he is an A&P) decided to try the same procedure as you have
suggested below. He used a vacuum cleaner exhaust to pressurize the crank
case and some soapy water to check for leaks. The front crankshaft seal
blew bubbles and he found it was damaged upon removal. He has replaced the
seal and is confident the problem is solved but I can not give you the bottom
line because the annual and subsequent flight are still to be completed.
Good luck!
paul, LIV N94PT still going strong

My next
step is to pull the breather tube off the air oil separator and use some low
pressure compressed air to pressurize the crankcase (engine off) and see if I
can find some
leaks.
