A cold start this morning resulted in a cloud of white smoke from the exhaust that lasted about 10 seconds - smelled like burnt oil. The Forester behaved normally afterwards. The only thing remotely different is that I’ve been parking perpendicular on a slight incline overnight at my new place for the past two weeks - I’m guessing it’s just a fluke, but time will tell.
Something to keep an eye on, I guess.

Oil leaking past the rings? I know these are legendary for piston slap, which can be diagnosed by ear.

You have a mid 2000's forester right? These are some of the best built and tend to not be oil burners or so leakers.

I have yet to meet a Subaru that doesn’t eat oil in some way. My last Outback did it before and after a brand new EJ251.
I used to get a puff a oil smoke on startup but it was only like 1/100 times.

It’s a 2009. The last of the N/A EJ25s seem to be quite robust.
It hasn’t had a repeat in the last week, so I think it was just a fluke.

Maybe due to how I parked? It hasn’t done it since, so I think it was a fluke.
Interestingly, a failing timing belt tensioner produces the same noise as piston slap, and is quite often a common failure point and the cause of that noise.

As long as the oil consumption is low, why worry?
