Default Car was smoking

My 2005 Forester XT engine was smoking from the right side of the hood even when I had enough antifreeze in the overflow reservoir. I'm worried about the smoke since Subarus are the mother of all gasket issues.

Is it coolant or oil smoke, it could be a leaking valve cover gasket, or seeping headgasket and the fluid is running toward the manifold during turns, and causing the smoking issue. But get it checked out if it's happening and you do not have a good understanding of what's going on

check upipe for oil drops, if its valve cover its not super expensive, does it have a specific smell to it? or just smoke? if theres not much of smell its probably an oil leak, if thats the case it could be a headgasket or valve cover gasket as PW mentioned. i hear that the most common area to leak from is where the coil pack/spark plugs enter, which would be easy for you to see moisture from an oil leak.

if you were driving a while and it wasnt too much smoke its probably not too big of an issue, you could just have some oil on you and still get around with no issues, but if it was a quick thing its probably a bigger leak than you want to play with. either way its nothing to let sit.

One other thing to look at. The passenger's side CV boot. If cracked, it will throw grease on the up-pipe.

I had a tiny leak at the turbo oil inlet and it was burning oil. Scared the **** out of me sitting at a stop light and smoke starts coming out of the hood (multiple times). Let alone the college kids crossing the street saying "you need a tune up man" haha.
