<VV> white smoke, valve train noise - need HELP!

[Norman C. Witte]

White smoke means a new Pope has been selected.

Seriously, I have been having a white smoke issue with my '65 Corsa 140 that
I have not resolved but I do know that it is a carburetion issue.  I have
isolated it by switching the carbs left to right and watching the smoke
change  banks, which you can do with a 140.  You might try the same thing,
though obviously the valve noise is a separate issue.
