Exhaust smoke at idle

dayhkr

All,

I spent all weekend looking into this issue and everyone's suggestions to see if I could find the root cause. I finally tracked down the issue to the check valves between the valve covers and the intake pipes. Apparently the shop that installed them didn't pay attention to the direction of the check valves, I noticed the arrows on the valves were pointing towards the valve covers so basically I was pressurizing the crank case. I switched these around and took it out for a drive to validate the fix. Since this change has been made I have seen no smoke from the exhaust any longer. Not sure if this will help anyone else out but its a quick fix if you run into the same issues.

Thank you for your help on this.
