We all have a tube from the valve cover to the intake manifold and I think we all have a larger tube from the valve cover to somewhere else. On mine, the larger tube went to an oil separator that was vented to atmosphere and drained to the oil pan. I changed mine because it was blowing oil out and all over the separator. After my ring job, the larger tube goes to a home made oil separator that drains to the oil pan and vents to a "rubber glove", at the moment, other wise it would go the intake tube after the filter and before the manifold. When the engine is at low RPMs, all the air is sucked out of the glove, when I'm running at speed, the glove blows up to tight, but is not vented. Here's what I think: The air is sucked out at low RPMs by the manifold draft and blown up while running because manifold draft drops when the butterfly is open and the pressure to blow the glove up must be coming from blow by.

Is it possible the glove is blowing up just because the air is warm?? just a guess.

I think your right, Then again I may be wrong. The crankcase does get some blowby no mater what because there is no thing as a perfect sealing piston ring. Thats why there is a tube going to the intake, to get rid of this by sending it back to the combustion chamber. Im not quite sure what the difference is between this tube and the one that is susposed to send oil mist to the canister which recondenses it and drains it back to the oil pan. I'm thinking that the loscation of the larger hose is like in refactory system (but different) in that it picks up from a position in the head cover that has more mist and the other tube comes out the top. I have eliminated the tube comming out of the top because of the supercharger.but still have the canister. As far as the glove goes, I suspect that the pulsation of the air pressure in the intake manifold is pumping it up. I'm thinking that the kinetic energy of the air coming into the intake manifold is ptting it at a slightly higher pressure then the pressure in the crankcase but then when the engine is sucking the pressure is slightly less then in the crankcase. Now I'm going to guess at this one. A PVC valve that we don't seem to have unless it is in the canister allows the air to get out of the crankcase but not go back in. If there is a PVC valve in the canister, it could allow the glove to blow up but not deflate except to slowly when at higher engine speeds. I'm now 100% sure of what I'm saying here so maybe someone else can chime in.

I think that would have to be some serious Blow-by, You still have you PCV valve in place right? Either way, My Trooper has a filter inside that cap on the CCP canister, I dont have any oil residue outside of the canister.

Went for a 62 mile ride yesterday and popped the glove, it was one of those gloves that the doctor wears for exams. maybe I ought to put a pressure gauge on and see how pressure it build, or does anyone know the bursting pressure of a glove :o:lol: say what????

Thanks Rick, been watching the forum for a while now, so i feel like i know everyone! lol!

I agree with you Kinarfi, Its a lot of pressure, but you also cant judge the pressure of the glove at burst, oil breaks down latex. Hell if i were you I'd put a breather cap on it and ride.

BTW: Totally off-subject but how are you guys going about re-locating the headlights on these things, I love my Trooper but the darn headlights seem so out-of-place!

As Leadfoot suggests, that's just what I'm gonna do, plug the end of the hose back into the air intake after the filter and before the intake butterfly and go riding and forget about it.

Welcome to the forum Leadfoot, but no hijacking allowed, :D you need to start your own post about headlight relocating. It EZ.

Welcome Leadfoot. Always good to have new people to help with getting things solved on the forum. Where are you from? Hopefully you can get to the next jamboree.

Welcome Leadfoot. Take a look at my gallery and you will see what I did. Unbolt them and mount them in the same location under the fender. Original location looks like the dune buggies of the 70's.

Kinarfi, are you using a Latex glove? Maybe your Trooper is allergic to Latex and causing swelling, LOL !

Pull the Oil cap off the top of the valve cover and see if it releases some of the swelling. May take a couple of minutes. Also try starting cold with no crankcase pressure with the Oil cap off and see if the glove swells. Just install a slobber tube to nearly the ground and just let it vent to the atmosphere.

Thanks guys, great to feel welcomed! I'm from Georgia, near Atlanta, Dont quite know how this Joyner made it all the way out here but hey, I'm not complaining!!! But anyway, Ill check your galleries and see how you guys did it! Thanks!

No, Used to ride Teleco before they closed it up, not many places to ride anymore around here. Wish there was! I'll second the east coast jamboree!!

Count me in if my Joyner is running when you guys plan the ride. I live in Rockwood, Tn. not far from Windrock. I don't know where brimstone is, is it in Tn?

      Predator 670 manual oil pressure gauge
      By Jim Kessell
      Hi All
      Just installed a predator 670 on my Landmaster. My question is can I remove the low oil pressure wire fitting and plumb my mechanical gauge into that access point?
      Thanks in advance for your advice !!

      BMS UTV sluggish acceleration issues/ final gear oil maintenance concerns
      By bms stallion owner
      hello, my BMS Stallion 600 is having accleration issues. the manual fails to show final gear oil diagrams very well... I have the owners manual and suspect issue is associated to transmission , I want to check the level of the gearoil. I located a drain plug (but not the fill plug nor dipstick). It will run - but wont exceede 2mph. Troubleshooting suggestions or comprehensive manual suggestions? Thanks

      Please help 2021 Axis 750 crew won't shift into gear and found milky oil on inspection
      By BMurph
      Hello everyone! I am new here and have no experience with UTVs but I am quickly getting some. I have a shifting problem where I can shift through all gears without the engine running but as soon as I start the engine I can not select a gear. Yes, foot is on the brake and yes the pin is being pulled to go into reverse if I was to try going into reverse. The shift lever does not move. I adjusted the linkage to get more accurate shifting with the engine off so I know those are now correct. I opened the shift lever housing to inspect the teeth on the gear and found this picture below. Why is this oil so milky looking? I assume with oil like this I'll need to replace the wet clutch as well but am not positive. Does anyone have any input into how to flush this system and get things shifting correctly? Thanks in advance for all the help!

      2021 Axis 750 crew having shifting issue and found milky oil
      By BMurph
      Hi everyone. I am new here to the forum and am excited to learn from all of you with more experience than me with UTVs. Our Axis750 we use on the hobby farm started to have some issues going into gear. Yes, foot is on the brake and completely stopped as required with these machines. I thought it was the linkage and adjusted it to where it is accurately shifting with the engine off and key in the on position. I start the engine and it won't shift gears (yes foot is on the brake). I thought maybe it was the shift lever teeth so I opened the assembly and this picture shows what I just found. I assume this means the wet clutch would need replaced too while draining and flushing the oil. What else should I consider or be looking at? Any idea what could cause this? I don't see visible leaks or cracks in the system anywhere. Thanks in advance for the help!
