After topping off all fluids, and flushing coolant system, truck was sent out on road. When it came back later that day, no oil showed on dipstick and oil was present in cooling system again.

The 6.0l diesel is noted for having oil and fuel enter the coolant system. If it is oil then the oil cooler has failed. The oil cooler is located the the center of the engine under the intake.On an F-series truck the oil cooler is below the oil filter housing. It can be identified by two things. The low oil pressure sensor and a small blue or orange hose is connected to the cooler. If it is fuel in the coolant then you have a cracked head or cracked injector sleeve.

How can you tell if you have a blown head gasket in a 2003 Ford Explorer if no water is in the oil

Water in the oil is not the only symptom of a blown head gasket. You can have a blown gasket where the cylinder gasses are being injected into the the water jacket only. This will overpressurize and overheat the engine. There is a test that can detect this using a coolant sample from the radiator to test for hydrocarbons present in exhaust. Lastly, the gasket can blow to the exterior of the engine, allowing compression gasses to escape the engine block. The quickest DIY test to determine the possibility of a blown gasket is a cylinder compression test. The compression should be approximately the same in all cylinders and should not leak down quickly. If it does, this indicates either a blown head gasket or possible valve issues.

2009 f550 diesel 6.7L engine has oil in the water and have to add water all the time.

You should get it to a dealer or a good diesel facility asap, it sounds like a blown head gasket-driving it like that will damage crank and cam bearings or worse, so it is not worth taking a chance-these are prone to blown head gaskets btw.

If you have water in the oil and the head gasket is ok, that leaves a cracked block or a warped head.

The radiator of my 2003 isuzu trooper has a mixture of water and diesel now, and per mechanic, we have to replace the overhaul gasket kit and cylinder head (though without testing), can we just proceed...

how did the diesel get in there? are you sure its diesel fuel or is it motor oil? then it could be head gasket problem. Or trans fluid, which would make it milky pink? Then it could be the trans cooler in the radiator leaking. If someone accidently put diesel fuel in it then just flush it out. If it has been in there long enough to start ruining hoses then replace those. why does he say gaskets? how does it run? does it overheat? then maybee head gaskets. and resurface heads.

2003 f250 won't start

Is this a small amount of white smoke or a lot of white smoke? If it is a lot of white smoke it could be a head gasket problem.

1. Do you have coolant in oil or vice versa?
2. Pull spark plugs and inspect for plugs wet with coolant.
3. Do a compression test and check for a low cylinder.

If you have issues in any of these points you will need to replace the head gaskets.

Oil in coolant and engine will turn over and will not start...2005 Ford F450 Super Duty 6.0 Diesel

oil in the coolant generally indicates a blown head gasket. If the head gasket is blown, oil and coolant could be getting into the cylinders. You should have a mechanic check it out. I don't know a whole lot about dianosinng diesels. If you can get the glow plugs out, turn it over and see it any water or oil blows out of the holes.

Diesel in coolant resevoir

you could have a blown head gasket, have a compression check done to see if there is any low cylinders,

a head gasket failure does not always allow water to get into the oil, the failure point can also be between the water jacket and the cylinder bore
