Less than 10 hrs on a 2010 rzr. I clean the air filter after every ride.

I had a normal ride yesterday , no indication of trouble or check engine lights etc..
When opening the air-box an excessive amount of oil was in the air-box. I checked the engine oil and that was down to the add line?

Any idea's

a photo may help what you think as alot might be OK.... are we talking a few table spoons or 10 oz??? alot of time what people say is alot really isn't...oil spreads easy and looks like their may be alot but really not.....also what /how were you driving at the time .....alot of heavy gas and high speed driving will force oil out the breather and also cause alot more oil use so it may or may not be ok try to get a pic plus if you measure the oil added it will only be a few oz to fill back up from the line....remember it only holds 2 qts total

I seem to have the same issue,But at the same time my oil vent is leaking also,I made a gasket but that didnt work. Not sure why Im getting oil blow-by, checked my vents ,all seem to be ok. So Im still investigating. Will be watching your thread too see If any of our razor buddies can help resolve our issue.
Good luck and please let me know if you find any possible causes.

Azriding,

I know you will have a little oil in the air box, but I had similar problem with excess oil in the air box also. Two weeks ago, I had riden about 100 miles on fairly easy trails, before I ride I have always checked my my oil, since I seem to go through oil more than I did on my 800 sportsman?? and it was full, and was I was done riding the 100 miles I checked it and I had almost gone through 1qt.oil the oil was barley on the dipstick.
When I opened the cover I found excess amount of oil and a smell of gasoline there was so much oil it was starting to seep through the o-ring. Being that
I am still in my warranty period, I called my dealership and took back to them and it's been there a little over a week and now this the second time I have had in. The first time I had it in I complained how much oil I was going through, and it was in for first servicing they contribute it that the engine was still going through it's break in 400 miles and a rings may not be seated. So now they they have back and they did do a a leak down test and found the the pressures in each cylinder to be at 175 psi which I guess is within normal ranges but also have found it to have high pressure not sure how this plays out ?? and the tolerances on the rings are off. So they replacing the piston and rings waiting on parts.

a little oil is normal, that is where polaris vents the crankcase.

protector, you didn't go through 2 quarts, if you did, you would be getting a new engine. if you see oil on the dipstick, you are probably only a few ounces low, as was stated earlier. this oil seeping will only occur at high revs, for long runs.

2 qts in 100 miles ..sorry but not believing it....first a rzr only hold 2 qts and if you used it the engine would of siezed up. and also if you used 2 qts it would not show up on the dip stick.... and if the leak down was normal Polaris wouldn't let then tear into the eng....


its possible your not reading the stick or capacities right and are over filling your eng this alone will cause many problems...oil foaming...excessive blow by...ring failure and possible engine damage.

are you talking about the vent gaskit on the valve cover..if so donot use a solid gaskit it wont work corectly..it uses a o ring the breather is plastic and is know to warp and leak...also a few have gone out with too long of a bolt but long hard riding it will seep....

oil blow by is normall...befor all of you think their is a problem take a photo and post it....

I have attached a picture of how much oil I found in the air box. where I ended up adding a quart of oil. Now I could understand if I was going balls to the wall losing that much oil, but that was not the case.

Thanks for all of the reply's. The forum is a huge help for new RZR owners like myself.

I worked on the RZR this morning to verify a few things based upon the initial responses to my post.

It was a tablespoon not 10 ounces of oil . I added a few ounces of oil to the reservoir and it was back to the safe mark.

Ran it for a while on mostly flat ground and the air filter and the oil were both fine, this time.

I had the rzr at glamis and have to be heavy into the pedal to make it go up some of the steep hills.

In summary, I am gathering if you are into the throttle all day , on steep inclines and declines, and it is 95 degrees like it was yesterday it is not uncommon to see a small amount of oil in the air-box.

Thanks for the great feedback!

From what I read, he said he only went through about 1 qt not 2 qts

thats because he went back and edited it ...he said 2 qts in the post...as to the photo he posted that is about 2 tablespoons of oil..not alot. on a new eng you will have more blow by but his is a little on the high side but not alot...id drive it more and keep a eye on it...

heres my issue... i have an aftermarket air intake that puts the filter right behind the drivers head in the bed. i lengthend the vent tube and put an k&n style filter in the end, and it sits up in the bed by the air intake. i changed oil thursdsay, used a k&n filter and amsoil synthetic. drove it 1 time friday night with no issues. took it out sat and it started blowing oil out of the breather tube. i dont mean a lil oil, it filled the bed enough to were it started running through the holes and down onto my motor and exhaust. i checked the oil and for some reason it was reading over full at this point (dont know why cause when i changed oil i only put in 1 3/4 qt and it showed full). so, just incase i f'd up and put tomuch oil in we wrapped a rag around the breather and went out to see what it would do, again it spit out oil, enough to completly soak the rag and put enough in the bed to start leaking through the holes in the bed and on exhaust again. checked the oil again and it barely shows on dipstick now.
it doesnt smoke any when running, doesnt knock, revs fine, but i do have a constant preasure blowing out of breather hose. we took a reed valve off of a friends and put it in mine, and same thing happens. im going to do a leakdown on the motor but i wanted to see if anyone has run into this before. i would think if a ring went then it would smoke, but i dono. thanks
