Looking for a service manual for our side by side. Nothing applies to a 600. Could also use good schematics. Air filter box filled with oil, thinking we need to replace the PCV Valve? also hole in air filter chamber tube. If I go to BMSMotorParts.com they only let you contact them by email. We're pretty good at fixing our vehicles ourselves and a service manual could help with guides but can't find one. Is it possible the 600 is the same as the 500? This is driving me nuts!
