Exhaust could still have oil in it, run it a bit more to make sure it burns out. Had the same problem when mike_ie did his Isuzu conversion here.
quite possible as the exhaust was very oily/dirty when I took the turbo off.
But would this happen more under load when theres no smoke at idle?
Maybe the higher airflow brings more gunk into the exhaust leading to more smoke?
what do people reckon about this as a hypothesis?

EGT pre turbo 160 degrees at idle when its under load it could be 600 degrees
This might explain it
I have had a few Saab 93 and 95 with turbo failures over the years, 1 in particular broke the shaft and pumped most of the sump of oil into the intercooler and out the exhaust. Very nearly had a hydraulic lock due to engine oil ingestion!!!
Took a few drives to get all the smoke to stop, ended up with a new cat converter too, drained heaps of oil from the intercooler. The flexible engine pipe joint also soaks up oil, basically it will take a while to burn it all out.

The Isuzu 110. Solid and as dependable as a rock, coming soon with auto box😊
The Range Rover L322 4.4.TTDV8 ....probably won't bother with the remap..😈
any way of getting rid of the oil thats burning off & causing the smoke other than driving it? I'm a bit wary of p**sing off other road users
TIA

Errr, no. Just find a few long hills and cane it. It'll soon be gone.
