I installed the half Raven inverted oil system a couple of weeks ago. I had been avoiding aerobatics until I installed this. The system works really well. No more oil coming out the breather and going down the belly.
The install was not too difficult, just had to figure out were to mount the can and route the oil return line. I put the can on the left side of the engine mount and I ran the return line along the left side of the engine, across the front, to the drain in the right front corner of the sump.
To install the supplied fitting into the sump, I had to remove the exhaust and intake pipe. I didn't get a picture of the fitting.
The drain line needs to slope down. Don't want high and low spots. A smooth slope will help the oil drain back to sump.
Fabricated a tab to attach an Adel clamp.
The original breather line gets modified.
I bought the half Raven with the hardware kit from Raven. I had to supply the breather hose, exhaust gaskets, intake gasket, and some Adel clamps.
Probably have about $850 invested along with 10 hours of labor.
