Hi,

I'm looking for a compact oil separator for my Marquart Charger.

If someone has one used that they can sell, or recommend one of another manufacturer I would appreciate it. There are several other styles available, but I don't know one from the other and would value some input on the different models. Here is a link.

This one is simply too large for a place on my firewall.

Thanks,
Glenn

Glen:
Are you trying to make an inverted system, or control blow by?
If inverted:
Try to find one from a factory Pitts, 1971 to about 1974, or whenever they started using AEIO engines. They were made in-house and had a flat back side, and not as round as the Christen ones?
Also, check with Doug Dodge, as I think he makes something smaller?

This is just for blow by collection to route back to an oil scavenge line.

You could make one, there's not much to them if the system isn't for fully inverted flight.

Are there any plans available? Cut away drawings ? Principle of operation? Anything that would help me design and build one?

I don't have anything to show but a brief description would go something like this;

The breather line from the engine connects to the separator through fitting that is tangent to the inside wall of the volume. Lets say the volume in this case is a can that is round with a flat top and a funnel-shaped bottom. As the engine breathes through the separator any oil in the stream contacts the inside of the can and the oil sticks to the surface. The air exits the can through a standpipe in the center of the volume. The bottom of the can has a drain that connects back to the engine case, gravity causing the oil to flow back into the engine case during normal flight. The location of the return port on the engine should not be below the oil level in the sump as this would allow oil to flow into the separator through the return line.

The too big $49 one is the one that came with my project. I installed it but have only taxied with it about .2 hr.

Routed return into old paint can/slop pot for now. Tie wrap has been replaced with hose clamp.

It doesn't have to be on the firewall.

If you make one, you can put scrubber plates in there. Disks with slots, each clocked a little different to help precipitate the oil. Don't restrict the crankcase breathing, don't have it so small to not catch the oil, and make sure it will drain back in the crankcase.

Mine is mounted on the engine mount. Don't mind the mess, maid hasn't cleaned the wiring up yet:
