If I hold the rpms up around 1050 when at stop lights, etc. I get no smoke.  If I let it idle back down to 850,
then it will usually smoke for a few seconds when I take off.  I guess my next thing is to pull the turbo
and replace the seals.

Thanks to all that responded, your comments and suggestions were all appreciated.  I will let the group
know the results of my turbo teardown and rebuild.

Thanks again,
Jim V.

  I'm thinking its more a turbo seal than valve seals. Valve seals usually are pretty consistent, go from not leaking to getting progressively worse over time and you will see little puffs for each cylinder that is pulling oil in the intake guide. 

  When going down the road the turbo is spinning very fast even if you are not pulling power, and it normally will seal well running. Its when the turbo spins down and stops that the seal will leak, which is your scenario. Pull the exhaust and take a look, you should be able to see where oil has run down from the lower part of the turbine and out the pipe and coked.

  Is your oil pressure set to high for the turbo seal? 

  Some things to check.  Mark Durham

    How about valve guides?

    This does NOT occur when the car is in gear and running down the road.  It
    will smoke after idling for a minute
    and then accelerate, and stops after about 30 seconds.  This is usually a
    large amount of smoke.  This does
    not occur every time, but most of the time.
