Need help diagnosing rough winter starting

[xweezyx]

Hi. Now is the time of year that my car starts falling apart. It starts very ungracefully. The colder it is, the worse it starts. It always fires up right away, it just misses like crazy and puffs blue smoke (this part scares me). Once it warms up, it purrs, especially since I adjusted the wastegate. I bought new glow plugs and a reamer even though the old ones tested fine. I had never reamed the holes, so i thought maybe the old glow plugs were bridged to the head with carbon making them ineffective. They were infact caked with carbon, all of the plugs came out shinny on the sides of the elements. I did the procedure and was excited to fire it up... Nothing changed. My oil consumption it a little high, but not crazy. My intake system seems very oil. It seems like a decent amount of oil is being thrown out of the crankcase vent. The oil cap test checks out fine. I am confident that my glow plug system if working properly, am I looking at something more serious? There is no sign of blue smoke other than when it is cold and missing. The blue smoke just smells like diesel, but I am running synthetic, which maybe has a milder smell? I have yet to check my injectors or timing chain. Thanks for any suggestions.

edit: No WVO has been run in a few weeks, so there should be none in the system.
