need a little help here I have a 2003 diesel quad cab two wheel drive 143500km(89700m)
what it is doing when it sits over night and I fire it up in the morning it give me no smoke on start up but after it idles a bit it smoke blue.( the smoke does have a oil burn smell to it) This only happen when I step on after it been idling like a minute or so. there is no puff of smoke on start up. it has been using a oil too like 2L in 6000km. when it is warm up there no smoke. There is no blow bye. motor run strong. I did put new seal and seats in the valve and had the head checked.
this started doing this like around 30000km(18750m) after the new short block


At 76000km(47500m) I had to have a new short block put in. reason 5-6 injector failed and wash the cylinders (warranty job)

my truck has a smarty jr set on 2 for towing
I change fuel filter every oil change
I run fuel additive in every tank fuel
all this truck does is 90% pull a 10,000lb trailer(98% time on pavement)
fuel mileage is still good
I use mobil delvac 1 0w/40 100% syn

 

check your turbo. it could be leaking from there and its pretty cheap to rebuild if thats the proble,

 

that what i think it is the turbo seal I got a new turbo on order from industrial injection a viper series 63.

 

i would install that when you get it and then watch to see if you have the same problem. that turbo is gonna have slower spool up then stock. it is worse if you have a manual

 

take your intake off and check that turbo
