Subject: [FlyRotary] Oil Scavenge Pump vs Custom Oil Pan

Hi All,

I have decided to install an oil scavenge system to return the oil fro= m Tracy's gear box and perhaps from my turbo as well.=C2=A0 I am really= getting tired of all the oil getting all over everything.=C2=A0 It clearly= seems to be coming from the area between the RD1B and engine, which means = that it is probably coming past the RD1B oil seal.=C2=A0 Tracy calls for a = nice big line and downhill only run of the oil to a point that is higher th= an the oil level in the sump.=C2=A0 However, there is precious little eleva= tion drop and I have not been able to achieve those requirements with a gra= vity only system.=C2=A0 If I run the oil level very low in the sump the pro= blem is improved, but I think it is time for a better solution.

I am considering either a custom oil pan that allows for a deeper drop= of the oil, or a scavenge pump.

The benefit of the custom oil pan is that it can be an improvement in = weight over the stock pan, and requires no moving parts or power and is unl= ikely to fail.=C2=A0 The scavenge pump is nice because it would be an easie= r installation and will probably be more effective at fixing my solution, t= hough I do worry about adding another possible failure point.

1) Soliciting pinions on the decision between Scavenge pump and custom= oil pan.

2) Recommendations on someone who makes custom oil pans and pickups?

3) If I choose a pump, does that solution require a tank or can the dr= ain lines be connected directly to the pump?=C2=A0 This would create a suct= ion on the outlets of the RD1B and or the Turbo, does anyone see a problem = with that?=C2=A0 Drain oil from the RD1B too fast?=C2=A0 Bad for turbo bear= ings?=C2=A0

4) Would I need 2 pumps for redundancy?=C2=A0 I am leaning that way, w= hich means I am leaning more toward custom oil pan.

5) Turbo drain back seem adequate, which means I could use the pump to= isolate the Gear Box oil, allowing for different oil there.=C2=A0 Thoughts= on this option?

Thanks for the input!
