hi I'm new to this forum. I'm hoping to get some help with 2010 850 knocking and spitting oil out of plug in top of stator cover. I had the pcv freeze 2 years ago so I replaced valve cover with updated cover, everything ok for 2 yrs. This fall I had oil in air filter so I removed the felt filter on pcv and no more problem there. Machine locked up on me after a long ride and would not restart as if the motor was locked up, then after being towed for a few miles I tried and it started and ran fine for about a month then the same thing happened, wouldn't start and had to be towed then got it to start but engine knocking and belt smoking. Sorry about the long post and I know there's some similar posts. I CANNOT FIND WHAT CAUSED THIS, HOW DO I REPAIR, AND HOW DO I PREVENT FROM HAPPENING AGAIN. Was this caused from that pos pcv. I have a video of engine running but couldn't get it to upload. Tried talking to Polaris but that was of no use. Thanks for any help
