need some advice

first off i did searches for smoke, and none adressed slight smoke, they all seemed to be excessive smoke.

ok i have a 2000 f250 with the 7.3. i purchased the truck with 85,000 miles and it now has 102,000.it is has no chip, 6637 and 5in exhaust the truck starts fine in the morning, with just a little puff of white smoke. i have began to notice that it smokes slightly at idle and if i gun the gas real quik, even when warm. the smoke is a blue-ish grey color and is mostly noticeable at night when a cars headlights are shining through it. maybe the headlights are exagerating the problem... is any smoke normal? after searching through some threads i thought i should check my turbo, and the exhaust side was dry and the intake side had a little oil but it looked like it was from the ccv. i took the oil cap off while runnig it and there was a little smoke but not excessive. also my rear fender gets black with soot after about a week my questions are,
1 is any smoke normal out of the tail pipe?
2 could it be injectors, it runs fine?
3 am i being paranoid and should i just run it?

Thank you for your time and advice

i dont think it has a chip because it feels stock and it doesnt have black smoke on acceleration.

I would just run it. If you know someone that can do a buzz test and Cylinder Contrubution test I would do it just for S and G... but dont pay to get it checked out at this point. Some smoke is normal.

You shouldn't have oil smoke once it's warmed up.
Some black smoke is normal.

could a bad injector cause the engine to smoke blue/grey, also the exhaust smells very strong...
