topkicktech...and anyone else that's had this issue. It's NOT a dipstick issue. I'm no tech master by any means. I'm more of a mechanically inclined body man. I've had this trouble for some time, stumping many. After the process of elimination, it came down to a simple gasket!!! Everything was either new or restored when I put in a new engine. The gasket between the plenum and the throttle body is missing a vacuum hole on the drivers side of the throttle body. CRAZY SIMPLE FIX for what drove me (and many, many more) absolutely crazy!!!! I removed carefully removed gasket, punched a hole in it, reinstalled it, checked for leaks while checking issue...PROBLEM SOLVED!!!! See you on the trails!!! "Sherman Tank"
