Turbo shaft oil seal is probably leaking a little bit, though not ideal it isn't unusual and not particularly detrimental (mostly).
The white smoke indicates either a water or coolant ingress into the combustion chamber or an excess fuel condition. A small fuel excess usually results in a increasingly dark smoke, grey to sooty black and sometimes an increased diesel knock but large amounts of excess fuel results in white smoke which is unburned fuel.
This is often the result when the fuel injectors are sticking, dribbling, leaking and misfiring could also be a further symptom. Bad starting could be caused by several things needing attention but poor injector performance can be a major factor.
I suggest you have the injectors removed and tested.
White smoke from the exhaust.. sounds like you have blown a head or intake gasket,, you have antifreeze/coolant getting into the fuel mixture.. CHECK your oil for water/coolant/antifreeze contamination...These are the symptoms that your describe.. if you have oil contamination, DO NOT crank the engine again UNTIL AFTER you get it repaired...
please mark as helpful..thanks

Have you had the injector recall check carried out? There is a problem with these injectors and this produces the symptoms you are describing. I suggest that you contact Isuzu direct for help. They have been very helpful in the case of my trooper
SOURCE: thick white smoke coming from exhaust
I would think this will be a blown turbo.
These are fed by a small oil pipe and if the unit overheats (due to wear) - this oil fill feed directly into either the inlet manifold - or the outlet - exhaust.
If it is spilling oil into the hot exhaust - you will get a thick white fog. You can confirm this by placing a clear glass bottle or jar in the exhaust stream - and see if it gets a thick coating of oil on it. If it evaporates - it's water, if not - or feels oily - new turbo or overhaul.
Best get is sortd sooner rather than later - as you may be able to save most of it for an overhaul rather than scrap it if badly worn.
SOURCE: oil coming out of exhaust and whistling turbo
it sounds like your turbo has packed in firstly the oil seal in your turbo has failed thats why ur seeing oil from exhaust & the whistling from turbo is the vanes in turbo breaking up so i would advise not to use car until new turbo is fitted & inter cooler pipes and inter cooler itself are checked & cleaned for swarf from turbo you can check turbo by disconnecting turbo pipe &inspecting turbo vanes (fins) to see if broken up or any damage to chamber.
SOURCE: White smoke coming out of the exhaust when starting?
Hello;
Volumes of white smoke is an indication of water in the exhaust. A certain amount of vapor will be present on start up, but if it is different than what has been the norm for this vehicle then a check of the cooling system is in order.

White smoke means that you have a coolant leak. Two possible causes for that - either the head gasket is punctured and must be replaced or the head itself is damaged and must be welded by an expert.
Either way the engine must be dismantled to make a full diagnose and repair.
