I have oil coming out of the front drain in my air intake assembly. What could cause this? Has anyone ever had this problem?

Since motorcylcles and atv's don't use a pcv valve to vent crankcase pressure, there is just a straight ventline that goes into the air box, so a little bit of oil in the air box is somewhat normal, if you over fill the oil it will make it a bit worse. Worn rings or valve guides will pressurize the crankcase more than usuall and you will get an abnormal amount of oil in the airbox. If you have tipped the machine over, that could cause oil to run straight through the vent hose. Please post the year make and model of the machine you are talking about.

Did you change the oil recently?

When filling the oil you should check the repair manual for the correct amount of oil. The AC oil change kit provides enough oil for an oil change but not the exact amount. If you add all the oil you will have overfilled it.

Finally some engines check the oil level with the dipstick screwed into the engine and some with it resting above on the threads. If you think this may be the problem I can find the specifics for your model. Let me know.

I asked him for more info on his machine too. I think that was another one time poster, he hasn't come back since his original post on 9-29.

      Hey Guys, 
      I picked up my first ever ATV on friday. It's an 89 Big Bear. It has some cosmetic issues, but seems pretty decent mechanically. I did have trouble getting the idle tuned to the book spec of 1,300 - 1,500 RPM. I took the carb apart and cleaned it out. Somebody must have lost the spring for the pilot screw, as it's no longer in the carb. Also, I have a dual cable carb, I noticed all the IPL's show the single cable carb, but I see others on youtube had dual cable carbs. When I would adjust my idle speed screw, nothing would happen. I bottomed it out and it didn't seem to make much if any difference. When i pulled the carb apart I saw the screw doesn't even touch the linkage, it's too short. Do the two different versions have different length carb screws? I'm wondering if somebody lost the ordinal, replaced it with the IPL number for a single cable carb which is shorter, and gave up on getting the ATV to idle. If you hold the throttle just a bit to get it to the RPM range listed above, it "idles" great. Any ideas? Or any links to the dual cable IPL?
      Have you guys have good luck with the aftermarket intake boots? Or is this a buy once, cry once deal? I'm guessing the OEM units last longer, but there is a huge price difference. If you have had good luck with aftermarket, where did you get it? My current boot doesn't seem to have any air leaks, but it's encased in JB weld... 
      I'm getting a 9th digit check sum error on the ATV when I put the VIN in. Has anybody seen this before on a Yamaha? The VIN  number looks original as well as the paint around it. 
       
      Thanks,

      So I bought a 2001 Quad Runner 250 for my son/wife. Sorry I run a Grizzly 660.
      I’ve rode it many times with no issue.
      My son’s first time out, I could always hear him but feeling he ran it red line in first gear a lot.
      So this is what it was doing during/end of the 2-3 hour ride:
      - halfway though noticed smoke (oil) coming from front of the motor sort of under exhaust manifold. Once back at the truck, it was really noticeable. Definitely oil burning off. I’m thinking from the top end maybe.
      So quick inspection:
      - No leaks or seepage of oil that I could see
      - I pulled the plug and it’s black but not wet
      - No blue/white smoke in exhaust
      - seems to still ride fine
      - Engine still has plenty of oil
      But now that I’m looking at it back at the house - it’s a hard/won’t start when hot. It starts right up cold no problem but once it stalls when hot, have to let it sit for 10-15 before it will start again.
      It wasn’t idling before that trip so I jacked up the idle a bit as well but I think that’s a carb clean/adjustment but...
      Any input is appreciated.
      Thanks for any help.

      A friend has a 07 trx 400ex..the engine drain bolt housing has a couple of cracks where the drain bolt threads in and is leaking oil...a one had any luck sealing this area with JB weld or something similar ?

      Hello...first post.
      Have a problem I have not been able to figure out.  
      While back the fuel pump went out...replaced it.  I got maybe 30 minutes..maybe less before the new one went out.
      Replaced it again...same thing. Now I am sitting with two more new fuel pumps in reserve but do not want to experiment and blow out another until I have a clue of what could be wrong.
      Have checked electrical...seems to be fine but I am no expert. Also the fuse is just fine.

      Hello,
        Over the years I have always used a friends machine, and only ride a few times a year. Last week I purchased a 2002 Polaris Sportsman 700. The front diff needs a rebuild, the axles are very loose where they go into diff. My question is, both front wheels rotate forward by hand, but do not rotate the opposite direction. Is this "NORMAL OPERATION" I plan on rebuilding the hubs at the same time as the diff.....
       
        My question about the rear diff, it rolls as if the machine has a total POSI rear axle...……. I lifted the front end off the garage floor with overhead hoist, as I moved it sideways the rear tires skidded rather than rotate. Both would roll forward easy, but not go in a circle. When I drove the machine in the garage making a tight turn I could feel the binding and skidding of rear tires....  Even if the switch was in 4 wheel drive, when it's hanging in te air the ignition is off...….. with the machine in 2 wheel drive mode, is that HONESTLY 1 wheel drive to allow turning without tearing up the lawn? then it locks the rear axle once it's put into 4 wheel drive? I'm guessing the rear diff needs a rebuild also because there is something "BALLED UP" internally locking the rear wheels together?
        It's a old machine that was not maintained, I thought the wheels were all rusted, but it was 17 years off baked on red clay. Just wanting to make it a reliable machine. I have great mechanical ability, just lacking a little knowledge of what is suppose to be "NORMAL OPERATING STANDARDS"
       
      Thank you in advance for sharing your knowledge.
      Jeff
