Hi, My name is ***** ***** for the delay.
I will do my best to assist you
how many miles is on the truck?
how much oil does the engine use?how much and when do you need to add?
sorry i missed you,,does the engine light stay on?if so,can you give me the computer codes?
do you ever need to add coolant?
i can give you my thougts here
but,i dont think you will like it
sense you arent getting an engine light or trouble code..but,the engine does puff smoke at times.
the smoke must be cumming from somewhere,,sense you never need to add coolant.we know this is oil
it could be either the vlave stem seals or the piston rings itself
fact is,,the engine may have plenty of life left but,it may not be good enough to pass your tough emission standards
i would think the engine will need to be replaced or rebuilt..
you could try the valve stem seals..
