Hi guys, new to this forum and having a problem. I have a 18 hp kawasaki on a JD 325 and there is oil coming from the crank case vent, running down the airfilter and soaking it. I had the problem when it was new, took it to JD and they changed the tube and cleaner housing. Checked it 20 hrs later and still the same thing. I called kawasaki and they had a problem and said John Deere fixed it right and didn't offer any other advice. Any help would be appreciated.
