Fun times!
On Friday I went out to do my BFR and when I landed there was about a million gallons of oil on the belly of the airplane.
Took the cowling off, cleaned it all up.
Checked the oil, in reality only lost about 1/3qt.
The oil seemed to be collected around the oil cooler (right side bottom firewall on the 14), there was no signs of oil on the engine or near any of the connectors.
I couldn't find any leaks in the oil cooler. I took it off, pressure tested it (using only the "hold and blow" method and some soapy water). There were no signs of weeping near the elbows. No signs the oil cooler was the problem.
On the 14, the engine vent is pointing towards the oil cooler, dumping out over the exhaust.
The running theory at the field is that the vent line was clogged and came free dumping oil.
There was no indication in flight, no pressure drop or anything odd feeling/sounding.
My plan is to, while leaving the cowling off, taxi and run-ups to get the oil warm and see if any leaks show up.
Any suggestions or ideas? Thanks for any advice!
Oh .. and 1/3qt goes a LONG way
