It takes no time for the E85 to milk down my Brad Penn oil.
It looks like crap. i run evac system and thats all. there is a tremendous amount of moisture in the motor.
Talking to a few guys at the track who run E85, they are talking about "lean out valves" and running the motor 200 degrees and such. Does not sound good to me.
Is E85 really this difficult? Small Block stroker 418,W-2, roller, drag race set up.
Sounds rich but the lean out valves work... I never
had any milking in the oil once your in the range..
even without the lean out valve.. but the lean out
valve will save you fuel during the warm up

ive ran e85 for 3 years, no milking of the oil at all...I use Rottella 15/40...and im also like Cab I have a undersized radiator in my car...it builds heat much quicker than it did when I had a big 3 core radiator in it..i didn't like it taking so long to build heat..and instead of going leaner, I just switched to a smaller radiator...now im 170 or so at the line...and maybe 195 down the return road.

I run Brad Penn and have had no issues with milking even when the motor was pig rich at first, just like methanol,, heat is your friend to prevent moisture especially in humid conditions 
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

I know this has nothing to do with the E85 much but heat is a good thing not only forr your oil but for the "Iron Heads".. I was always told to achieve good combustion the motor needs to be around 190 degress for an iron head.. Just my  I will be running E85 this year with my small block W2 motor so this thread helps me out ! Please correct me if I am wrong about the heat to achieve good combustion.  Thanks

i run evac system and thats all.
Make sure the evac is working. If it is the header/pipe smog valve type the smog/back-fire valves do not last long. Once the disc falls off inside the valve you could be pressurizing the crankcase.
I gave up on this type of evac and just left the hoses off.

If you dont run exhaust you dont even need the valve
but at low rpm is when the valve helps.. I've run the
valve 8" away from the point where the pipe attached
the collector just to keep it farther away from the heat
and its all about the angle of the end of the pipe
and where its located in the collector for the best vac

Any alcohol fuel (methanol, ethanol, E85) needs proper tuning and procedures. Some pointers:
1) Get the idle mixture lean enough, rich milks the oil
2) Stage at 160-180F water temperature
3) Heat to 190-200 F before shutting down at the end of the night and pull the breathers for a while to let things evaporate.
4) Plug fuel vents, reinstall breathers during storage between weekends.
I never had any problems with the oil with E85 or methanol and I used Brad Penn all the time since I ran a flat tappet solid lifter cam. 2008-2013.
Any alcohol needs heat to work best. Don't be afraid to see the temps get up over 200+ on the return road or during a warmup. I warm mine to 210 at the start of the day to put heat into the trans and oil, and it cools to 180/190 for the starting line easily. Ethanol will cool less than methanol, but works pretty close to the same temp wise.

I did dyno tune the motor(mainly the jetting) before putting it in the car, my car has a very small cooling system so it runs 180+ on the return roads at our local 1/8 mile track, ir will run over 200 F on the return roads at the 1/4 mile tracks, maybe that is a good thing
