Recently purchased an 08 F350 CCSB with the help of a few members here as it was an out of town purchase for me. Just finished the 800km (500mile) drive home and was largely without issue.
Background on the truck is a 1 owner, hwy driving rig. really clean but the owner told me it smoked 'sometimes'. It is DFP deleted, mini maxx tuned, turbo back exhaust.
Well, I fly in and take her for a rip. It smokes alright... Holy cow does it ever. Like I cant drive it bad.. Blue gray and smells of oil. Seller says it did this a year ago and he replaced a compete bank of injectors. Im standing there thinking turbo seal, as it really smoked bad at idle and taking your foot off on the road. No codes showing so I figure the price was sweet and off I go.
Get to my pop's place and change out oil and fuel filters before the drive home. Everything looks good, filters are clean, coolant looks good, no leaks, and OASIS was super clean to boot.
Fire her up in the AM (cold) and its white smoke everywhere! Smells like diesel, sounds like marbles in a blender and throws p0266 and p0302 (misfire) on cyl #2.
I shut if off, scratch my head and restart. Purrs like a kitty.. So off I go across the rocky mountains.
Its hazing pretty good down the hwy, and its got a bluish tinge.. I'm still thinking turbo seal and that #2 injector needs to be swapped too.
About 4 hrs in to the trip I pull off for a coffee, she starts to buck and kick so I limp it to the gas station and get a java, scratch my legs etc and wonder what now?
10 minute break, turn the key and she fires right up and off I go! No issue, no codes. 2 hrs later its pit stop time and I leave it idling and she starts acting up and tosses the same to misfire codes on cyl #2. OK, so this injector is toast. But, restart and she was fine!
So off I go, running good, and it looks like the smoke show behind me is getting down to almost un-embarrassing. Another hour, another pit stop and start up and she is running sweet.
NO blue smoke what so ever, just a little puff of black when I get on it and she pulls like a freight train. Running like a brand new truck!
I noticed what I assumed was oil in the tail pipe, but when I felt it the consistency was that of diesel. BTW
Running like an absolute champ when I show up at home.
SO, my question is, can the injector cause all of that and then just go back to behaving?
Thanks for reading, all comments appreciated!
