The valve adjustment itself should not effect a smoke problem..however if when reassembling if something is not tight or reconnected..you could have a problem.
911s are easy to overfill with engine oil too..too much oil and it will get into the intake..and smoke.
Oil level check engine running, at idle, engine oil hot..should be between the MIN and MAX marks. My 911 engines always like to blow off a quart if I run the oil level at the MAX mark hot..they always settled down to somewhere in the middle of the marks..

I can't say that I've noticed any change in idle without the oil filler cap on. If there is, it's probably not enough to notice while back in the engine compartment. I'd have to check the tach I guess to see if there's anything subtle.
I usually run the oil somewhere between the middle of min and max and 3/4. Since i noticed the smoke, I've kept it in the middle. My wrench suggested trying to run it a little closer to min to see if there's a difference.
