I know... been discussed at least a 1000 times already, and I've been reading up on it (yes, I used the search function), but still hoping to get some confirmation.

When starting my '97 2.5, I get the occasional puff of white smoke from the exhaust.
I know on an aircooled it's nothing to worry about.
Not so sure on the watercooled M96.

Mostly does it after short distance drives but recently it starts to get more frequent.

I removed the oil cap, but I don't notice any of the described symptoms there.
It came of like you'd normally expect and there doesn't seem to be much of a vacuum.

I admit replacing the AOS doesn't seem like a whole lotta work, but I'd rather not fix it if it ain't broke...

So, the main question remains:
Is it ok if I get the occasional puff of smoke when starting, or is it not supposed to do that at all...?
