Did somebody call me????
It is easy to tell steam from smoke, and I'm sure he would have notated steam if it were that.
The only way I stopped the smoking on my 80 wagon was to sell it!
I tried injectors (twice), valve adjustments (plural), IP timing, IP replacement, valve stem seals, thermostat (can't remember logic behind that one), made sure vac. pump wasn't compromised, same with sucking atf fluid back from tranny, my compression was 310, 330, 330, 330, 330. Didn't burn oil, blow by was darn near non-existent. Balls weren't missing in any prechambers. Chain was not elongated. Car missed horribly when first started. Had to work the pedal to keep it running. Would smoke like a train at idle and when coasting. Didn't smoke when accelerating or during high rpm's on the highway. Didn't smoke at all at idle when running diesel purge. Took about a minute to get to 60mph, and lastly, was getting about 17-19 mpg.
Hope your luck goes better than mine did.
Now back to your regularly scheduled programming........
Good luck!
