Kenworth with N14 Celect Plus Grayish White Smoke on Startup

Hi everyone,
I recently bought a second truck (KW t2000)with an N14, haven't gotten to drive it much except around a parking lot. My largest concern at the moment is at a cold start it'll billow a good amount of acrid white smoke until it warms up a bit, my other truck(fld120) with the N14 doesn't smoke one bit even in the dead of winter. From what I can tell there isn't any blow-by, I'm using the tissue in front of the dip stick trick so not exactly scientific. I'm thinking low compression because it disappears once warm, i don't think its head gasket because it doesn't have the sweet antifreeze smell either, it's just real nasty unburnt diesel smell. Could it just be way out of valve lash specs and be way to tight and leak compression off? It's an ESP engine as well, I don't have service records or anything on it but I got it for a steal. Also what are the opinions on the super 10 (non top 2)for long haul/regional, and the kenworth t2000 chassis in general?
Best Regards,
Paul

 

Hello again. I took the truck out for a short drive, just relocating it from one place to another but it involved getting on the highway and accelerating. I noticed quite a few things but am unsure whether or not I should group them all under this thread or split them up, for now, I'll just focus on the engine issues. During my pre-trip warmup, I noticed that there was a pretty noticeable miss, I also could hear a popping in the exhaust as if there was fuel igniting in the exhaust or very late into the cycle right before the exhaust valve opened. The miss was audible at normal idle and I could feel it at high idle, but while driving you can only just barely hear it. It doesn's seem to have a negative effect on power as this truck did appear to feel like it pulled a bit harder compared to my other N14, but that might just be the ten speed vs the nine. On acceleration, there isn't any smoke I can see, it appears to only smoke when warming up or revving at a standstill, or maybe I just can't see the smoke while driving. My largest concern by far has been the stop engine light and the truck going into limp mode, its done it twice so far, both times while I was driving on the highway and had a bad shift(missed shift), if I shut it down and restart it's back to normal, no check engine. I'll be getting a non-contact thermometer pretty soon to track down the malfunctioning cylinder(s) but other than that I'm unsure of where else to look.
