      This topic has 3 replies, has 2 voices, and was last updated byRon S. 4 years ago

      July 6, 2019 at 12:30 pm just installed new envirovent ccv on 1996 250 cummins. Previously had walker system. i am getting some “wafting” smoke from the small filter much like a previous post by another member on the forum. Have it connected to valve cover. I followed the photos on your sight with no problem on install(nice job to you all). Can i expect this to go away after running it? Just doesn’t seem right to be have that much fumes in the engine…
