Crankcase breather/missing fitting?

I've been having a issue will excess oil being blown out of my breather hose. I took my stator cover off to get a look and compare to pictures online. Mine appears to be missing a fitting that is shown in the attached image. Parts diagram also shows the breather hose having a T split where mine has possibly been altered and is a straight hose to the swing arm. Parts diagrams doesn't show me this internal price that I appear to be missing. Any idea if this is some type of case breather mod or just a missing part allowing excess oil to be blown out. I have drained and measured the oil and it's not being over filled.

Make sure the hoses aren't kinked.

I've seen that thread. His is an 05. Mine is an 08. My breather comes out at the stator cover and not the actual case like his. He's also not addressing a oil blow issue like I am experiencing. Thanks tho

You can put the hose from the crankcase. Mine is an 06 and that's were I put it from. If you look at how the stock set up its the same thing your just doing seperate hoses instead of being with a T then to the filter.I'll take a pic when I get home. I had oil blow by before and that was because I had a scored cylinder wall... so maybe your piston rings?

Engine has just been rebuilt. Runs good. What about the missing fitting? If you look closely is appears this fitting runs to where it sits behind a slight block off, mybe a splash guard type of thing. Mine is missing and is just a hole there and I think its blowing oil out with the air

One with, one without. Mine is missing. I can't find this part and suspect it to be the oil blow problem

Buy the part and install it if your missing it. Maybe they forgot to put it when they put it back together after rebuild.

That's the tube that connects to the hose... you should buy it asap. That piece is the one were I connected my hose and then a filter at the end. That's the part that's different on the 04-05 models

This is on the inside of the stator cover. It's looks identical to the outside fitting were yes it connects to a hose. This is on the inside where the air would escape up and out. 04 and 05, the breather does not come out at the stator cover, totally different. I cant find this part in any oem diagrams. It will however show the outside fitting where the hose connects to but does not show it as a removable/purchasable part

You should show the parts or Mechanic at your local honda shop. They have to have that part.

I tried looking for it and I guess it's part of the stator cover. Might want to buy one off ebay they're like $40

.79 quarts, 690ml. With that being said. I measured the drained oil and got less than 500 ml back out.. it's spitting more than it should. I too assumed it was from slight over fill/high revving. But it continues to spit every ride. Enough to where if i stop after riding it will drip a couple drops off the frame by the swing arm.
