Hey guys, yesterday my 800 died in some water. i didnt think i was in that deep, had my 600 in deeper water a lot more. had to get pulled home, pulled it apart, found water in plugs. Pulled fuel tank, draind it pulled throttle body and intake lines and found a slice in the breather hose to the air box and to the valve cover. didnt think much of it, called dealer for a new hose today and parts counter said there is a RECALL on this hose. so if any of you have a 800 CHECK IT OUTi just looked up the part number and my buddy has the same part on his 700 carb. so you all might want to look into checking this hose for a split in it. it is located just under fuel tank goes from valve cover to air box. my is split about 1' from the valve cover. took my 7 hours to finally get all the water out and get it running. dropped engine oil to drain over night. suppossed to go riding saturday out west and trying like h_ ll to get er going.

 

I was reading ATV Mag today and I swear I came across something saying recalls with the 700 & 800s. I have a 700 EFI so if anyones knows any information about this please post.

 

the breather hoses are notorious for getting spliced or pulled off the airbox and water and muck getting pushed into the valve houseing and destroying your motor, its crutial to get it taken to the dealer as soon as possible to have it taken care of. and replace those stupid clips they put on it with the big ratchet clips so it dosnt pull off

good luck

 

Does this mean I should bring my 700 in?

 

hey guys, here is an update. went to dealer to get new hose today. opened it up at the counter and asked why it would split. as i started to say it split right here i noticed a slice in the NEW hose!!!!! i asked what was up with this. 2 parts guys and 1 service guy were like huh?. now on top of this when i called yesterday they said it was a RECALL, now they say oh that was a recall on 2001 and 2002 models. but the part number in my book changes to a new number. so back to the slice in the new hose, i ask why there is a slice and no one has an answer. 1 service guy comes up with, because it may need vent, and i say but it goes back to the air intake box why cant it just vent there and no answer again. i said i give up and just give me the new hose. so if any of you can get an answer from someone, please let me know.

thanks, Scott.

 

There was a Tech Service Bulletin a few years back with the hose accumulating condensation and freezing so they deleted the filter and put insulative wrap around the hose with a relief slit in case anything freezes. It supposed to be like that.

Polaris along with many other brands have a crankcase ventilation hose, freeze up problem.
The tube, which originates from the valve cover and enters the air box, can get blocked with ice that is formed by condensation. When this happens, there is no way of relieving crankcase pressure and the weakest part of your engine will fail (valve cover, dipstick, oil pan, etc.)
The correct procedure (recommended by Polaris) is to cut a small slit in this tube, as close as possible to the valve cover (lots of heat and will never freeze in this area) This serves as an escape route, for any pressure should the hose freeze up. Otherwise if you blow the valve cover and do not notice it guess what happens? (I know of several cases in my area that led to motor failure due to oil starvation). This only happens in extreme cold -20c and below and will happen to quads stored outdoors that do not get to thaw out, they simply build more and more ice until it's finally blocked.
Another thing to check is that the hose is routed so it does not have any low spots. ( a U shape somewhere along it's path) If it does, the condensation/water will not be allowed to flow freely into the air box where it is supposed to go and when it dips below freezing, you get an ice cube in the system.

Edit: Polaris has now released a TSB (Technical service bulletin) regarding this matter. The onus was put in the dealers hands to contact the customer in areas only where cold temps are seen on a regular basis. In general. Canada and the Northern States. I would not rely on your dealer contacting you as we all know how lazy some can be! If you own a 02, 03 or early 04, the TSB applies to you. If you have a 04 and are not sure, just look at the PCV hose which goes from the front of the airbox (left side) to the engine valve cover. If the hose is a plain black rubber hose and has a small in-line filter, you need to have it done. If the hose is a black rubber one but has a foil type insulation sleeve around it and no filter, then the mod is already done from the factory. You can see this hose by simply removing the seat.
The TSB is #S-03-05 and the part # is 2202744

 

thanks for the update, i figured it was a matter of time before someone would has a sensible answer.
