ORD Magnum puking oil

So I have an ord magnum in my truck. 6l90 to Magnum to Ford NP205. Anyways I have been trying to stop it from puking oil out of it. Today we drove the truck, all day, and got it up to 100 MPH on the freeway. It pukes oil out sometimes but today it puked out a lot of oil. Trying to get this figured out. I will be calling ORD (off road design) tomorrow

I have two vents on it, I called ORD and they said run atf so I put in some redline trans fluid. I need to revisit this with them.


I have heard that full synthetic power steering fluid will cavitate so we run the swepco stuff. Think this could be the problem?

Any help would be appreciated. Have a trip to the rubicon in two weeks and wanted to drive there and back

My buddy has the same issue and swapped to ATF with no significant change.

He replumbed the system to an old power steering reservoir set up to drain back. It was a bit of fiddling to get the lines to flow nicely. He’s only had it installed for a couple of weeks but all good so far.
 
I have an nwf eco box in front of a np205. I had the same issue when I ran just a breather line. I’ve since ran the line up to a catch can so it can expand and then drain back down once cool. All good now, I run redline mt 90. I also added a sight tube to check level periodically. Mine only holds 3/4 of a quart so you really have to know how much is in there before a highway drive, at least I do for peace of mind.

There was a recent thread.

There was, but I seem to recall the consensus was the Magnum didn’t seem to have that issue. At least the UA people who’ve seen hundreds or even thousands of road miles on the magnum units, from my memory, said they didn’t suffer from that issue like the Ecobox does. 06h3 and TIMMAY!
 
I had this issue with a rear axle and wondered about running the breather line into a small finned cooler. Same idea as the catch can I guess, but with fins :laughing:

Basically this mounted vertical with the filter on top.

I do not have the magnum but wish I did, I ended up with an old school behemoth box I got for cheap, I think it was about $500 (before they got bought out and fixed their shit)

I personally know and have seen 10 plus magnum box's working on the highway, in extreme heat, etc. without issue. I have heard of some puking oil but it was usually because it was overfilled. The one thing I have seen with NWF is overheating their doubler box, I have never heard of an overheating issue with the magnum. I have never overheated my behemoth. It seems to be a NWF issue (they have gen 2 now that supposedly fixes this)

Anyways, I run a catch can so if it does puke it will drain back. I saw years ago on UA that watson had a long breather running to a gatorade bottle to monitor an puking but I think that was more for science to see if he had puking issues and how much (if any.)

I would start with making sure your oil level is perfect and not overfilled. instructions say 3/4 of a quart.

I am not sure what breather/catch can/possibly a cooler that the gomez brothers run but they race KOH with a magnum box in front of an SCS case and are definitely over 100 mph.

This, I ran a breather upside down from a block so water wouldn't be able to drip into the overflow tank

Stephen is the owner of ORD and can probably chime in if you didn’t speak to him today.
 
My 2nd gen scalloped NWF case hasn't had an issue at all. 3/4 qrt. Sight tube still showing same oil level everytime I stop. Avg trip is 4-5 hrs to wheeling trails. 350-400k km. I also ran my breather up to a catch can on the fire wall shared with my tcase. No issues. Just running 75w90 synthetic.

Make the breather tube longer and don't overfill.

I believe he figured it out and a seal was pushed out somehow

Yeah the seal pushed out of my np205 t case, couldn’t see it at first with all the skid plates on the truck.

The magnum does puke oil still and ORD states that a catch can is the way to go. When I install the new engine I will be doing the catch can at that time.

Thank you all for the help except Mike Honcho 😂, I didn’t know that NWF knows how to answer their phone or even call back for that matter. My NWF bearing retainer is the one the seal pushed out of.

mannysouza NWF has been good about answering emails for me. I believe Kris is the tech guy up there.

Glad this was figured out. I was told to run a breather hose with 2 or 3 loops in it up to the firewall for my EcoBox to help try to alleviate burping all the fluid. I might steal the idea of a finned cooler to work as a catch can.

i was thinking about adding a drain at the high level mark with a sump and pump. The pump will squirt cooled oil into the planetary. Can you post a pic of where the oil sits when full? Maybe I lower the level further to prevent windage. I'm thinking the main issue is the lack of forced oil into the pocket bearing. To oil the bearings enough the oil level needs to be well into the planetary. The planetary is creating a crap load of windage that whips the shit out of the fluid and overheats it. A pto driven pump would be tits, no electrical stuff to go wrong. A couple well placed oil squirters would be enough to keep everything happy. Thoughts??

Eccentric pressed over a shaft and a boss for an external fuel pump would be way "cleaner" of a design though.

Circle track rear end gear oil pump driven off the rear output.
 
Generally speaking, power steering fluid is just hydraulic oil.

As is ATF aside from added friction modifiers for clutch packs.

Have seen ATF spec'd in many thing that it's technically incorrect for. Pretty much anything without clutch packs should use hydraulic oil instead. Sometimes it's just to stick with a single fluid, like in a T Case, other times, who knows.

Not familiar with Redline trans oil.

It ATF or MTF? MTF is a version of gear oil.
 
I just run 1 qrt of synthetic 75w90 in my NWF box. Whatever I can find locally.

I’ll try to get a picture today. It’s a little over 1/2 way up the case, although I have 3/4 of a quart in it and apparently I need 1 quart. Nwf keeps changing the amount. When I built it in 2020 the paper work said 1/2 quart. Then I had problems with it popping out of gear on a highway drive. Nwf fab said 3/4 quart because I had updated version. Now 1 quart 🤷‍♂️
 
my box used to puke some also. but i think the combo of a expansion tank and me over filling it some it is good to go now. i look at the sight tube often and it stays right at the 3/4 mark so that seems like where it wants to be.

That's exactly where mine sits. (I made my own site tube)
