sorry....but is my 7 dead?
Been having hard start issues like its struggles to Rev when cold then backfires a bit then runs fine it also stalled when cold....
its been running fine thought in fact drove 6 hours in it yesterday and was a dream
I woke up to move it this morning and same hard start but its now blowing smoke like crazy along with it...
Video upload shortly
BTW no mods and has oil and coolant...not leaking either

your oil control o-ring is done.
see this pic. this is what my car was like, when I first got it, the smoke was something like "urs", but then it got worst and worst, up to the point that if I don't start my car in a week, holy mother load of smoke will come out and smoke the whole block (I'm not kidding)
the ring just fall apart in pieces, I didn't touch it, it just fell off like that. The metal ring it's actually still in spec (barely any wear in fact), it's just the rubber piece is done. I'm not sure about your engine but mine, the previous builder use the wrong/outdated type of rubber O-ring, it gets hard, cracked, and finally in pieces becomes completely useless.
Good thing is, This is a cheap and easy to fix (if this is ur problem)
bad thing is, it will still cost you a few hundred ASSUME you can do the labor yourself and you already have all the tools to do the job.

Stock stuff is good enough for most people as long as they actually use the right part.

the vitons are a little more of a pain to work with but they are also reusable, if you plan on tearing down the motor periodically for racing applications.the OEMs square off in as little as 1k miles or a few warmup cycles.the OEM inners i almost feel are too thin for adequate sealing, although they work.

I might give Viton rings a shot in my next rebuild. sometime next year I guess.

don't feel bad, the n/a 7 is a dying breed mainly due to low resale value. turbo owners have less of a difficult time in the decision to build a new motor for their car because they can at least have more enjoyment from the car before taking the hit when selling the car. FDs are the only ones where you won't take it in the pants as badly when selling it. there is actually a few shops that deal exclusively in rebuilding FDs and selling them as rebuilt and they make a decent profit at it, no way that will ever work with FC or FBs.
