Depending on where you place the tip of the overboard dump and how you cut the
tip can determine whether or not you suck oil out.
As WCG mentioned bad pistos willl pressurize the case. Placement of the drain end
in a low pressure airflow will "suck" the oil out.
Another common problem is overfilling with oil those dip sticks aren't exactly
precise and sometimes running a quart less than you have been can fix the problem.
The tip of the tube needs to be placed in a high pressure area and cut at a 45
deg angle facing forward so as to provide a slight back pressure.
Robert dont worry 414C ain't gonna siphon. If you start blowing oil you have an
engine problem.
It does sound though like Randy's problem was dueto something unrelated to the
above.

I am a complete ignorant as compared to all of you, but in 20 years of
aviation I had been told by most mechanics that is not necessary to use mineral
oil, after tops. I just did one 20 hours ago and used 100 like always, will
take your advice under consideration.

Another way you can lose oil.....
Some years ago I was flying a turbo 206 for photo survey work. It was
bitterly cold and the engine was preheated. We were sitting there just
slowly warming up when I thought I saw something out of the corner of my
eye. I turned around (the 206 has back window) and I saw clouds of smoke
blowing out the exhaust.
The aircraft's owner was running an air oil seperator, to recover oil to try
to keep the camera lens clean. (I no longer believe in agressive crankcase
vapor recover, for a number of reasons.) Even with the engine preheat, the
seperator remained cold enough to freeze solid from water vapor exiting the
crankcase. The crankcase built up so much pressure it blew a quart or two of
oil out of the engine in no time. I've heard of engines blowing out the
front seal from this. (I think my dad had this happen in a C-180. I'll have
to ask.) I thought this was the reason that the 500 series relocated the
breather to out the top near the exhaust, instead of the original system.
I did think about the failure of those two engines with the replaced jugs. I
can't imagine the type of engine oil as being responsible for losing a rod
on a new jug. Ring clearance too tight?
