I received my new hub a few weeks ago and noticed oil all over the hub. It's the "quiet" version and it did sound quiet at the time. I had the wheel built around it and now the hub is much louder. I'm assuming it's because most of the remaining oil leaked out as the hub still shows signs of oil leakage. I contacted Project 321 about it, but they basically told me not to worry about it and ride it.
What's the point of adding more oil if it's going to leak out?
I'd like to open it up and investigate, but P321 doesn't have a manual for the new hub. Tips?

I suspected that feature was going to generate some complaints. Imagine if you continue filling those oil pockets every time you clean the hub without ever replacing the seal. Eventually it will be gone in just a few minutes.

Why not ask P321 if the new hub disassembles like the older version, there is a video on their website?

I don't care what component I install I always verify fluid / lubes (brakes, suspension forks, hubs etc.) Pop off the freehub and relube using an approved oil.

I wouldn't gauge a hub's sound level until the lube has settled. Any new hub will be much quieter until it breaks in.

Maybe you didn't hear; They have been touting these "oil pockets" as a feature to keep the hub quiet(er). If all the oil flings out constantly then it's not really working as intended.

I have not had one of the hubs in my hand but I am unaware of a hub that has a positively sealed drive system. This topic came up @ one time but rather than keep the lube in the hub it was to keep the elements out. General consensus was it would cause too much drag.

Who's to say "all" the oil has come out unless it is popped open and examined these "oil pockets". I would also inspect the integrity of the oil seal. IMO its a tough call to purchase a hub and have noise level expectations w/o hearing one first hand before purchasing.

Obviously the oil level has dropped to the point where it's much louder than it was when I received it. I'm beginning to regret purchasing this hub knowing it's going to need a disassemble/"refill" every week to enjoy one of the features I bought it for> Quiet.
Oil dripping down the spokes onto the rim isn't a feature I asked for.
I never had a hub leak oil like this does.

This video demonstrates how my hub sounded (quiet) when I first received it and how it sounds today (1st loud cut) about a month later after the oil leaked out. Not my video
So, in reality, it's the quiet version when it has oil and the louder version after it leaks out.

Did you mention all these points when you contacted 321? If so i'd call again and talk to someone else, if possible, maybe you will receive different info. Irregardless oil all the way to the spokes say's something isn't right. The way I look at it you have 2 options disassemble yourself to inspect the seal or ship the wheel off to 321.

Where did you purchase the hub?

here's the link to the new drive system, internals, and oil bath. this is just a press release type of thing, they haven't updated the website yet.

Project 321 - New Drive System

also, Pumpkinbiter (aka Jake) works at Project 321. You could PM him and see what he has to say?

I'm very interested in how this works out, I'm about to buy the SS version of this hub for my new build. Suddenly I'm a little hesitant. I just called today to get some details, almost placed my order...

I bought the hub straight from P321. I just got it apart and it's just damp with oil. Not enough inside to drip out.

I have 2 brand new high POE hubs in front of me right now I9 Torch & Profile Racing Elite. Upon dissasembly you could barley moisten a paper towl w/ tha amount of oil in both hubs. Most high POE I have worked on required only a small amount of low viscosity oil.

As I mentioned you would have to have a real oil seal to contain oil in the hub - how does the 321 seal look?

I just noticed quiet version uses different pawls. Do yours look like the quiet version :Project 321 - New Drive System

Mine is the "quiet" version. It was quiet before all the oil leaked out in about a month of no use.
Jake from P321 is sending me a new seal. Hopefully that's the issue.

Dude, seriously... Stop trying to put this on him and do a google search. P321 stated to the media that the holes were intended to hold a fill of oil. Not a mist, not a smear...
Obviously his wheel wouldn't have oil all over it if they hadn't filled it up that way at the factory.

Looks like the only thing holding the oil in is that thin red rubber face seal visible in the second picture down. And the oil can also escape between the axle and inner race. IMO, oil loss is inevitable in with this design. Skip the oil and use a little thin light grease, or maybe a little Phil's Tenacious Oil, as you would with other pawl type freehubs.

I was told using grease would void the warranty. I am curious how light grease would affect the function of magnetic pawls.

I stated what other hubs of similar high POE use for oil amounts nowhere did I say OP was @ fault just trying to cover all the bases for the OP - calm down. As I already mentioned I don't know of a hub that holds oil in that doesn't have a positive sealing system, told OP to check the seal and agreed something isn't right.

I will add that consumers dealing with manufactures can be a slippery slope. You contact the manufacture like a pedestrian that has the right away and in fact the manufacture may have a differing opinion of your take on their product.

Installed the new seal and put in the oil last night. I just got home from work, checked the hub and there's a drip coming down from where the seal is hiding. Maybe this is normal? I'm curious how much oil loss will occur when I'm riding. I'll find out soon enough. For non use days, I'm gonna have to remove the rear wheel and lay it down to prevent leakage. Not impressed. Phil's Tenacious Oil is coming tomorrow, but I can't use it. ;)
After closer examination the oil is dripping down my spokes. 6-8" down. The oil they recommend, Dumonde, it way too thin.

dude, seriously? drip of oil anywhere on my wheel is a no go. IMO this also means that your rotor and brake pads get contaminated each ride. I thought this was a nice inovation I might try myself, that was before I knew this thing is filled with a lot of oil.

I can take my old hubs and stuff them full with grease making them very silent.

anyway, thanks for your report, I wish you success returning this junk. I am definitely not getting these myself. as stated before the only silent and less drag hub remains onyx for me.
please let us know how this ends.

Has Project 311 offered replacements?
Yes, they wanted to see how the different oil worked. I'm trying to avoid shipping the wheel to them and having it rebuilt (Pete did a great job) Depends on how the CK lube does. If that doesn't stay in or it causes issues, it's going to P321.
