Jim, here is shot behind my 115 at about the 20 minute mark in it the break in,as you can see at 18% there is a veritable flood of oil and it is washing the factory lube, (the black stuff) out. This would have been at 5,000 rpm, low throttle, three turns out.

BTW Jim,
With the dual Check valves, you can easily pipe that oil right out past the rudder, free and clear of the plane.
I have been playing with a catch can to capture that oil. The oil could probably even get re-used with only a simple straining

I do something similar with the exhaust, but externally. I have a soft brass line that is strapped to the muffler with the end beveled where it meets the exhaust. The other end is hooked up to the breather. Keeps the plane clean, just get a bit of slime on the landing gear and rear stab.

Same here, that is pretty much what led to moving the line right inside. Just to tidy things up a bit. It also seems to keep the oil blast pattern narrower and more concentrated , winding up with less oil on the plane.

Saito 50 GK run after re-build
1st prop tried: Graupner 11 x 6 rpm exceeded 11,900
Prop=======Xoar 12 x 6 as pictured
Plug=======Fox Miracle
Exhaust====Davis SoundMaster in cowl muffler, (neighbor lady in bed recovering from operation.) The exhaust is nearly silent.

Yep,
Likewise with the homemade aluminum canister on the beefy Saito 125. Weiighs about the same as the Saito.Easily reconfigured to suit in cowl as needed.

The canister is a real nice piece of work Gary.
I thought I saw that Toledo Special cowl in the background of some earlier pic you posted. Looked like it was undergoing some bodywork repair. Man, that old girl has seen some air time.

Those cowls are hard to find and a bad crash busted that one into 4 pieces. Yep, it was payed back, spliced and coaxed. I then made a mold from it. Have laid up a new cowl yet so I just screwed that one on the repaired again plane.
This version of the canister is very quiet indeed. A lot quieter than I had anticipated . I actually like it.
I added a different baffle to the very modified YS shell in the above pic. My wife even commented Sunday on how it just " purred along" so smoothly. The electric guy flying at the same time was actually louder.

Jim,
The oil isn't actually getting dumped into the muffler. That brass tube passes through from front to back . The plane used to get very oily on the bottom and up the port side. Now the sides both stay clean and only the bottom gets slimed.
Not sure what you were trying to do with the break in but with two check valves, yes you can inject additional oil to a running engine. You still need to allow air in as well.
knowing that much of the oil passing by the piston is used my thoughts to add fresh oil to the crank case was only for the brake in. yes> air is needed, my thoughts on sucking in air was to only add a squirt of oil to the header tank every few minutes as the engine brakes in, this would allow both air and fresh oil in.
know this now about me, for sure I may not be the best engine mechanic, but I am very picky about certain things, and when it comes to braking-in a new engine (specially like a Saito) my mind strives for the best result, so if I can add fresh oil to my rod bearing that may help me get to that result. plus I will enjoy testing my method.
I like the idea of pumping the used, vented oil to the tail of the plane. it seems to me that with using a tube that long should help hold a bit more oil in the case

"Used"?
Do you really think that single pass from top to bottom does the oil much harm?
Here I am, pondering catching the vent oil, straining it and using it as part of the oil in fresh fuel!
No kidding

"harm" naa, but it's diluted a bit.
that 82 sound so cool !!

They came from RCU, the email addresses weren't sold and it's not spoofed. If you dont want them just click un-subscribe and you won't get them, and it doesn't affect forum notifications or pw reset emails etc.

The stuff looks and acts like new, even measuring the viscosity by drip method. Oil costs about the same as nitromethane.
You didn't say which B-17 your son is riding(?)
I will post some pics of a flight simulator my buddies and I restored here at work. It was for the Yankee Air Force at the old Ford, Willow Run Airport.

One reason I bought the laser cutter is to build the Jan Hermkins 1/8th B-17. I plan to use 4 Saito's converted to CDI. Not yet sure if they will be 72 or 90, or something in between.
