The injector are along top of engine , the lines all run back to a pump usually attached to engine side, only unit with multiple metal tubes running out to engine top, removal of injectors requires some special tools. this requires good diesel knowledge and tools to repair either one.

SOURCE: oil mixing with Diesel and car emits white smoke.

The copper washers on the bottom of the injectors can give this fault if they are not renewed when the injectors are replaced .

If you have changed these allready and made sure you pulled them down exactly as the manual says in 3 stages then you may have a bad injector - see your Isuzu dealer .

SOURCE: water/oil mixing in 22r engine

yes it can mix, also check the timing cover for rubs from the timing chain. this is the common problem with 22r. many mechanics will tell you its the block but they are just trying to make money.

SOURCE: water is mixed with oil.

I think you have a bad intake gasket. These engines,(vortec v8 and v6 ) are well known for this problem

SOURCE: audi a4 mixing water and oil together hissing,grey/brown foam

That is not true oil and water being mixed can come from many different places. Such as a bad radiator which would cause transmission oil to mix with the water also alot of audi's have a water cooled oil cooler which are a very common cause of oil being mixed with with water. These type of oil coolers are located under you oil filter. They have water lines hooked to them which cools the oil and when they go bad the water and oil will mix. So dont be convinced that its your head gaskets it could be but not as likely. You can pressure test your oil cooler to see if this is the problem just romove it an plug one off the inlet or with rubber plug which can be purchased at you local hardware store (I found mine at ace hardware in there specialty drawers where they have all there bolts) then attach a air hose to the other outlet pressureize the system and place it in a bucket of water. this should tell you if the oil cooler is bad but be careful not to ove3r pressureize the cooler this could damage it and caust it to leak. 15 to 30 psi should be plenty.

If oil mixes in the combustion chamber, then you're up for an engine overhaul. Nozzle changes won't do.

Isuzu 4jx1 mixing diesel in water. what is cause. and how to remedie

Where are you finding this? Diesel and water would normally only mix if water was getting into the fuel tank. Are you sure it is diesel? If you are finding it in the coolant reservoir it is more likely to be engine oil. This usually suggests a blown head gasket.

Hi John, These days most oils are formulated to be used in both petrol and diesel engines but those formulated specifically for diesels should not be mixed. If your talking of a top up I suggest a flush with a good quality chemical and a lub service. If you have had a service carried out and changed the type of oil the same applies. Mixing oils can cause fast sludge build up which can block the filter, oil pump and galleries. These days most oils are designed to run both types of engine, but mixing is neve a good idea. Regards John

Can you mix engine oil

Hi Marsha, Many people mix brands of oil specified for either petrol engines and the same is true for oils specified for diesel engines if topping up, but it's not a good idea....It is a very bad idea to use an oil specified for one type of engine in the other. I would suggest never mixing oil manufactured for a diesel engine in a petrol engine or visa versa. The reason is that the diesel engine is dirtier than a petrol engine and manufactures of oil formulate it to have more cleaning chemicals than that used in petrol engines....Mixing the two can result in a build up of sludge which can actually block the lubrication system of the engine causing in some cases severe damage. Regards John
