Thanks for your input
I understand oil in the intake / intercooler could create smoke out of both exhausts.

I'll check the oil qty when draining the accumulator sumps. How ounces under normal conditions shud be there ?

Currently the oil leakage has not re-appeared on the turbo housing.

I'm getting a minor puff of smoke at start up from the passenger exhaust and then clear afterwards. This was not in evidence for the last 5 yrs, so it is still a question for me as to the cause.
