I have a 2005 Ford F350 6.0 Diesel and It wont start after the motor gets warm. It also starts rough when cold. When it is running it runs great. Any help would be appreciated.

I had this same issue and luckily my F350 2006 was still under warranty. Basically there is a high pressure oil system that has a tendency to leak internally. You won't see any oil leak. When cold the oil has enough viscosity to keep the pressure sensor from not allowing the engine to start. When the engine is warm the system doesn't reach required pressure to allow the engine to start. In short it's a Ford dealer repair. Good luck.

Blew oil out of the water resevoir

We just had the exact same issue with our 2004 F-350 with a 6.0. The oil cooler had failed. Its an expensive fix. But less costly than a blown head gasket.

Getting diesel in oil

Sounds like you might have a bad fuel injector that is dumping fuel in a cylinder that is running down the cylinder into the oil. Could be a fuel pressure regulator that is not holding it's pressure causing fuel to do the same thing.

Is it running good? Smoke a lot?

Oil in water but no water in oil. 2004 F-350 6.0 diesel

Check the oil cooler, oil pressure is higher than the water pressure. It hasn't got bad enough to push water in at 16 psi, turned off.

I have 04 f350 with a 6.0L it cranks and has a fuel at the fuel pressure regulator, but will not start. what can i check next?

I'm beginning to find out that this is a very common concern with these year model Ford diesels. There are several things to make this happen. First try checking all of your fuses, then try the fuel shut-off switch behind the passenger side kik panel just below the glove compartment, There should be an access hole there so you can reset it. Then you can check your injector module relay in the fuse box under the hood. There is a high pressure oil sensor on the rear of the passenger side valve cover that if it fails will cause your truck not to start. There is also a cam sensor located on the front of the engine near the timing chain cover that would also cause the same issues. If none of these fix it you need to get it to the shop. The only other things would be the oil pressure sensor beneath the intake, the high pressure oil line that powers the injectors could be leaking, the high pressure oil pump could of gone out or the injector control module may of shorted out, all of witch need to be done by a factory tech. due to resetting and reprogramming.

Oil leak

check your pcv valve usually if it gets plugged it will blow oil out where it can.the pressure builds up in crank case thats the pcv valves job to relieve the pressure
