    What would cause my 1976 K-10 /forums/images/graemlins/truck.gif to smoke in park. The exhaust smokes like crazy when left in park, yet when in drive sitting still there is no smoke. I'm puzzled. Any info is greatly appreciated.

    Check vacuum leaks. Especially the vacuum to the tranny.

    Good luck.
