It's either the bypass valve or the solenoid that controls the bypass valve. I've personally never had the solenoid fail... it's always been the bypass valve.

Even still, the 2.0 and 2.3 are like 90% the same externally. The bypass valve and solenoid are the same regardless.

The P1110 code is - in my experience - usually caused by a ruptured bypass valve. The vacuum hose attached to it will no longer hold vacuum, so the bypass valve can't open.

Nothing there should be wet. The vacuum hose is for vacuum; the bypass valve controls air flow. No oil or fuel or anything there. If the bypass valve is oily, probably your PCV system is damaged or maybe the turbo is failing and sending a bunch of oil through the intake.

No car will remain reliable without proper maintenance - the question probably becomes whether fixing what you've got will cost more or less than replacing it.

Based on everything you've said thus far, what I would probably recommend is:

1. Have the shop remove the oil pan, look for sludge. If there's a problem, that would be when you know to cut bait
2. Have the shop remove the oil feed for the turbo and either clean it or replace it
3. Install the PCV kit Mimmi linked above

Probably at that point, there's little reason to think the car won't continue on.
