i bought this truck from a guy a few months ago, he had a piston melt down on him so he bought a used motor that supposed to only have like 90,000 miles on it.. ive been having some problems with it not starting in the mornings unless i had it plugged up and it hasnt dropped below 32 degrees yet, so i changed the fuel filter and i havent had to plug it up since, then this happened..
he swapped the good motor into the truck?
did you check for an exhaust leak inside the engine bay?
is the exhaust smoke smell like fuel or coolant?
shoot your exhaust manifolds with a temp gun to see if all of your exhaust temps are close, if you have one that is low or runnign cold it could be a dead cylinder.
when you say hard to start does it sound like your having trouble starting it like it has no fuel? once it starts can you restart it?
you might want to pull the valve cover, and take a screw driver and put it to the engine and use it as a suto "Stethoscope" and see if you can pinpoint where the noise is coming from, might be worth pulling the oil pan and checking the underside and the connecting rods for play.
pull the injectors and get them both
pop and flow tested.
until you start pinpointing where the noise is coming from can't really help you much beyond this.
Most likely you have a dead injector, or a worn VP-44, something that is causing a timing knock or a delay in the injectors pop open time, and as such is giving you a dead cylinder and can also be the cause of this....
but only more research into this will solve your problem.
