Is it ok to run the 914 like that? I found oil in the airbox and intercooler of
my 914. I'm afraid it's coming from the turbo so running without the turbo
connected
might be a way to check.

Try disconnecting the turbo airbox rubber hoses from the back of the carbs.
This will in effect give you a normally aspirated engine. Try a full power
run up and see what happens. If the surge disappears, then indeed you have
a turbo problem. If the surge remains, you've eliminated the turbo as the
source of the problem and should look to the carbs for a fix.
