[W126 Coupe] [W126 COUPE] California Emissions Issues

[Montgomery, Richard "Rick"]

I have a coupe with 165k on her.
She is burning a bit of oil.
 
After getting a gross polluter test result, I have done the following;
 
EGR Good opens and closes fine
EGR LINES CLEANED OUT  
AIRPUMP LINES ARE ALL CLEANED OUT  AIRPUMP IS ENGAGING ELECTRONICALLY
NEW BOSCH O2 SENSOR IN FRONT BEFORE THE CATS
SECONDARY CAT REPLACED WITH OBD2 FOR MORE CERAMIC.
 
 
PROBLEM REMAINING.....MORE VISIBLE SMOKE THAN BEFORE AS THE LINES ARE
ALL CLEAR.  CAR RUNS REMARKABLY BETTER BUT PUFFS GOOD ON TAKE OFF!
I WILL BE PUTTING 20/50 VALVOLINE RACING IN TODAY AND A NEW FILTER AND
RUNNING IT HARD JUST BEFORE THE RETEST...
MY MECHANIC HAS SOME TYPE OF ADDITIVE THEY USE FOR THE OIL TO KEEP IT
FROM SMOKING AS WELL...WAS GOING TO ADD THAT IN AT TIME OF OIL CHANGE.
 
 
ANY OTHER IDEAS.....WITHOUT TEARING CAR PART FURTHER....I AM IN DEEP
ENOUGH AT THIS POINT!
I NEED SOME PRACTICAL SIMPLE TIPS OR TRICKS I CAN USE TO GET HER TO
PASS!
