So you're talking about oil smoke from the tailpipe or engine compartment?
From the engine compartment, my experience is the same as Cory's, things will f-in' smoke from all the oil and lube on everything. From the tailpipe, don't really know, unless you put a crapload of lube on the rings and valve guides. I guess your turbo seal too.
I've never built a Subaru motor, but I wouldn't idle it too much longer without going out and putting some load on it to seat the rings before the peaks of the hone pattern break down too much. I usually go out and pound the crap out of the engine pretty soon after the first warm-up.

The heads?
Or could this be a valve sealing issue? I've had smoky exhaust before from a loose seal on some exhaust valves... but nothing this smoky.
For now, I'm thinking it's just "normal" burn-off of assembly lube, etc. Once the rings are run enough to start to seal up, if it's still smoky as hell, then I'll worry about what might be wrong.
