Vacuum leak - smoke test shows smoke coming from under the air oil sperator

I for got to mention in earlier posts that elevation has an affect on vacuum test gauge readings.
The gauges are calibrated for sea level.
So for ever 1000 ft. above sea level the gauge will show 1 in/gh less then it would at sea level.
So add back in 1 in/gh for ever 1000 feet you are above sea level to your gauge reading.
Hope that makes sense.

Makes sense - I’m at 800’.

Now I have a P0430 code with no other codes and everything running smooth. Going warm up the cats and take a look at secondary O2 sensor readings tomorrow.
