After roughly one month and 4k km's of owning a 2004 Toyota Sienna (3.3l 3MZ-FE), it started smoking upon cold start (over night). It's a noticeable cloud. It doesn't seem to be using much oil, as it's still at F on dip stick (although it was overfilled when new to me). It has 164k km's.
After some Google scouring, I don't see this as rampant for Sienna's - although seems common for Toyota owners. It's blue smoke, and my best guess is hardened valve seals. I'll replace the PCV - maybe that will relieve some pressure.
Anything else I might be missing?
EDIT: For those who have done this job on the 3MZ-FE, how much of a PITA does it register?
