260cc Linhai oil in air filter box

Recommended Posts

hi there folks

i hope someone can give me some advice on the problem i,m having with my recently bought atv , it,s a 260cc Linhai 4stroke engine from 2005 with 2300 Miles on it

and the problem is that i keep finding oil in my airfilterbox ,allot

and it,s not airfilter oil as i need a dry airfilter

it looks like it gets blown in thrue a tube that is connected from the engine

does annyone know something about this ??

and is it normal that air is blowing out the oilfilling opening with allot of pressure??

i noticed when filling the oil and having the engine running stationary

sorry for the misspells as i live in the Netherlands

and thanks in advance oakleyz

Are you overfilling the crankcase with oil? Does it have a site glass or dipstick?

The tube going from your Airbox is a Crank Case Tube.....The only way (the way I see it) the oil can get in the Air box is through there.....

2 Things can cause this...Overfilling the Oil which causes more pressure Build up thus the oil getting in the Airbox....Or,,,,,Bad piston Rings.....

If you dont have Blue Smoke coming out the Tail Pipe then its not the Rings.....

Another Thing......

You dont want a DRY FILTER.....All Filters(At least the ones that I know about) use some sort of Filter oil.....That is what Catches the Particles.......Dry is not good.....

Thanks for the reply

yeah your wright the oil comes in thrue the tube i can see that inside the airfilterbox

i don,t have blue smoke either and the crankcase was empty while the airfilterbox was filled with oil

and i did find out that my quad uses a dry airfilter

do bad piston rings allso cause a bad cold start??

thanks for the help

Well here is my Suggestion then.....I would Drain the Oil......Then I would fill it up with the Recommended Amount of oil.....Remove the Airbox and Vent Tube and clean with Carb Cleaner....Make sure that you Wipe it down clean...Reinstall....Fire the Bike up and let it run for about 2 min. then shut it down and Recheck your Oil...

Sounds to me like you had it too full to begin with.....Or,,,,,Have you ever had the Bike on its Rear End for long Periods of time?????

Hope this helps....

hi there i almost already did what you asked

i hav evenbeen driving for 1 hour instead of 2 min

and after 1 hour of dricing there was a drop of oil again in the airfilterbox

and i bought the quad second hand so it could be that the quad was on his back

and the owner never told me because it was an ex-rental quad

i,ll take a picture today and post it here

so you can see

anny idea about the bad starting is maybe connected to this oil problem?

Sounds like he did have it on its "Back".....Im glad that that seemed to do the Trick for ya....

On the Starting thing....It could be any number of things but where I would start first is the Spark Plug....Install a new one with the proper GAP....Make sure your Valves are Adjusted Properly....Carb could be a Key factor here too....You need Air/Fuel/Spark to start something...The first thing you need is Air.....Try taking the Filter out of it....Then Start it.....If it Starts easy then you know its your Filter....And So on

hi there again

just went to an ATV shop and bought a new sparlplugg and got some info

mine did look like the one "dry and wet fouling"

but no luck on the starting with a new sparkplugg

, the mechanic from the shop thought it could be the

electric choke on the carburator

just to replace this would be $140,-

and there hourly fee is $80,-

so i,m not quit shure to bring it to a dealer ....yet

because if it,s not the electric choke they probably to

will spend hours locating the problem and my pockets are emty :)

thanks for the help guys

      Yeah I know its been a while since I've been on but, I've recently aquired a 2005 Polaris ATP 500. As ya'll well know I'm sure that these things are notorious for faulty ECMs and they are made of unobtanium. I got this one from my brother. I've unpotted the old ECM and tested the components and have concluded that they don't flow the board properly from the factory so that's why they crap out.  I've also done some research and found that if you take the harness and Stator and flywheel from a 2004 its basically a plug & play application and it eliminates the need for the ECM. Why the heck they put it in anyways is beyond me. I'm going to devise a way to make a plug & play adapter harness that eliminates the need for the ECM and restores the wheeler to use. Has anyone tried this before and had any luck? I've been trying to locate a wiring diagrams online so I can compare the 2004 to the 2005 but they're pretty hard to find.

      Hi all. I've had a 1994 350 Warrior for 15 years or so, love it but, I'm wanting it to be a 4x4. With my limited knowledge I've come up with maybe a 2005ish wolverine 450 4x4.  I really need advise on what to look for though!
      I'm liking the prices on the early 2000s. The biggest concern is it fitting it my truck. I have a 2016 Colorado crew cab (5 foot bed). I'm not worried about length at all just width of the front wheels I think I guess...
      I think I heard that the Kodiak is the same as the Wolverine but it has a front locker??? I'm not overlooking other brands, I just searched around and came up with these.
      What do you guys think? What would you get for under about $5 grand, 4x4, that is relatively light weight and will fit in my pickup?

      I give it gas then it dies.any advice to fix?
    • By Ed Morris
      I have a 2001 Quadmaster. Bought it from the original Owner. Its in Excellent condition for a 2001. The guy said there was a carb problem when I bought it. It seems like it is not getting fuel. I took off the tank, cleaned it, replaced the gas with fresh Gas, Installed a New Gas Valve. Then rebuilt the carb with a Carb Kit. Started it up and same damn thing, seems like its starving for gas. It will also backfire out the exhaust while trying to accelerate. Now the weird part. I started it the other day and it ran great. We went for a ride and it ran as if nothing was wrong with it. Started it the next day and back to running crappy again. I was like WTF !!! ... Anyone have any ideas of what the problem could be?

      Ok...I'm gettin' me juevos ready to do an oir filter clean....
      Went to my local harley/quad dealer and he had me purchase the No-Toil kit (Cleaner, Air Filter Oil, Rim Grease)
      What I've read is that the No-Toil cleaner will NOT clean
      other oils off air filters....just the No-Toil oil....
      So, I've also read that others have cleaned their air filters
      in the kitchen sink, used gasoline, or used flash solvent....
      Looking for advice as I've mentioned I'm very mechanically
      DECLINED!
      I'm going to wash the air box seal in the sink and give it a good dry....
      One more thing......No-Toil or Bel-Ray for filter oil?
      Thanks!

      Have a 2011 Grizz 700 and for the diff oil the manual calls for SAE 80 API GL-4 hypoid gear oil. I'll be using Mobil 1 synthetic but as it comes in two different weights I'm not sure which one to get....either the 75W-90 or the 75W-140.
      The 75W-90 is listed as GL-5 and is recommended for use in 'high-performance vehicles like SUVs, vans and light duty trucks.' The 75W-140 weight is also GL-5 and is recommended for 'high-performance vehicles including sport utility vehicles, vans and light-duty trucks.'

      I'm going into my '11 Grizz 700 to adjust valve clearance for the first time and when I button everything back up I'll be replacing all the gaskets / o-rings. The 5 I'll be replacing include (from the top down) both valve cover gaskets, cylinder head cover gasket, and the 2 gaskets in the crankcase cover.
      Do I need to coat these gaskets with motor oil before putting them on like when replacing your oil filter?

      Hi All,
      Has anyone found engine oil in their air filter box. The must be little or no baffle between crankcase ventilation and that hose that attaches to the air filter box.
      I went to pick up my ATV today 60 miles away that they could not fix the jerky low speeds on and before I loaded it decided to check on this. Sure enough there was a good coating of oil with some pooling in the bottom of the air filter box. The air filter has oil on it too but is it a dry element or oiled element type. My guess from the color of it dry.
      I heard on a comment on my YT videos that there is a kit for this issue? Is this a CFMOTO fix?
      Thanks
      Kevin
