Watch those 850 XP'S when starting below freezing!!!!
 

hey guys just heard of another 2011 850 Xp that froze the PCV and blew out the plug only had 16 miles i just want everyone to be real careful when starting these things when it is below freezing cause not all dealers will cover these things when it happens, on a better note my dealer was on the phone with polaris today and there is ANOTHER updated PCV being released that is supposed to have a kind of presseure release built in. Amazing only three years in and they finally figure it out, o well better late than never, just be careful and get your dearlers to get on the phone and get those New PCV's ordered and coming as soon as they are available.

When mine is below 32f I pop the oil plug to keep pressure from building up.

But mine is always in a garage thats kept around 35 40f

I wonder if that update from Polaris will be a recall item.

not sure seems to me they are content to let the warranty run out and take the chance the customer won't bother and fix it themselves,

PCV fix
 

So do we call the dealer,or is this a cheap part we can install ourselves???Where is it located?Thanx.

the install is easy, but i'm sure you will have to call the dealer to get it, the PCV is located right underneath the seat on the right side towards the front of the ATV

looks like all the parts are around $40.00, going to get mine today, have to take the old one with me but dealer is paying for parts

i have heard of this also......however mine sits in an unheated shed and i have plowed alot of snow this winter....my warmup consists of starting up and letting it sit while i put coveralls on and then i start plowing.....done alot of cold weather riding this winter also......1200 miles with no issues......maybee im lucky this time....i hope

I've let mine sit in the driveway multiple times in sub-zero temps and not a problem til it happened. When mine blew I started it an let it warm up good - if not you may foul the plugs (don't even touch the throttle). I then pulled it off the trailor and got the shanty out of the truck, got dressed etc. When I turned the key to start it again - it blew.

I just e-mailed my dealer to see if I can get a new valve before mine blows out.
The machine isn't as much fun to ride in the cold now all i think about it is popping that stupid plug.

I agree just not worth blowing that plug gonna wait till I have the new ones or it's 40 degrees out
