I once had a similar experience when I accidentally overfilled the oil tank.
Unaware
at the time that the oil in the tank will siphon into the engine if it
sits for extended periods of inactivity, I checked the oil prior to leaving for
the airfield and noted that it was quite a bit low. I added a quart or so to
bring the level up and headed for the airport. Unfortunately, I didn't get
very far. Shortly after takeoff I started to smell oil. I immediately came
around
for a landing without incident. However, upon examining the plane I discovered
that a significant amount of oil had been forced out of the overflow tube.
It was then I realized what I had done. Never check the oil level without
first pulling a few blades through and confirming the burping of the oil tank.
Lesson learned.

"Hi All,
Last Saturday my test pilot started the ground testing. He
carried out the taxi checks, bedded in the brakes, did a fast taxi down
the runway, all the t's and p's perfect. Oil pressure 4 bar, The engine
ran quite cool, (no signs of over heating) All together he ran the
engine for about 45 minutes. When he taxied back to the hangar the
engine dumped most of the oil on the tarmac. Rather worrying!! We took
off the cowls and every thing looked o k. The pipes are correct (the
right orientation) and there are no kinks in them. So far the engine has
run for nearly four hours with no problem. Has anyone else had similar
problems? does anyone have any suggestions ?. It was going to have it's
maiden flight next Saturday, but !!!!!!!!!!
Cheers Danny (worried)"
