Sometimes when I let it set an idle for a couple of minutes it smokes blue until you drive down the road. Doesn't smoke when driving normal???
Had to dealer they say normal? Help driving me nuts.

Year, Model, Miles on it?

My 07 LBZ with 1500 miles on it also produces alittle "blue tinted" smoke at idle.
Not a DMAX diesel expert, but most all diesels with smoke alittle at idle.
Im guessin on mine that rings are still green. I,ll cure that with a good load this weekend.

Just remember this:

Blue smoke = oil (before ya start, diesel fuel is oil based, I meant crankcase)

Black smoke = unburnt fuel

White smoke = Air leak

All three = In Frame Time LOL
