Well first of all Happy Thanksgiving to all. What ever your plans are enjoy yourselves . The truck is down again , got a leak on the previously replaced o ring on the advance piston nut. But while pulling the intake to get pump out I thought i would run it with the intake off. I have a mist of fuel grey smoke pulsing out of the driver side egr opening. So I think i now have a problem with the head, cam, lifter , rocker, pushrod etc. will check compression and pull valve cover to check stuff. Any of the Guru's have any words of wisdom. Thanks again and be safe.( whatever that means to you). HAPPY THANKSGIVING.
