Your thread has been copied to it'* appropriate Section for better visibility, ( https://www.gmforum.com/showthread.p...80#post1517880 ) Thank You for joining and Welcome to the GMForum.com. Is your truck still under warranty. The two things I'm thinking off the bat are PCV valve or immaturely worn valve seat/*.
