Recently I've noticed a light blue haze at idle even after the truck has been fully warmed up just had the head gasket done and head studs put in when done so I dnt think its that anyone shed some light on what's happening oh and my oil level hasn't changed

 

Whats it smell like?

 

Just smells like exhaust nothing abnormal.... Am i just being paranoid you think?

 

check ur turbo... both sides .... sounds like oil issues..

also have u tinkered with the pump.. try adding a lil more fuel... might be burning soe oil off the rings ...... my ford used to do that ... turned it up a lil... problem solved
