Ford 05 Superduty Dully

[drwhit]

Hi
I have a 350 ford powerstroke with about 34,000 miles on it (STOCK). I was pulling my 5th wheel on the I5 when I noticed the Engine light come on I checked the rest of the gauges and every thing seemed fine. So when continued on about 100 miles down the road I stopped for fuel. Well when i went to start the truck it would turn over but would not start.

It was then pulled to a ford dealer and they have had it for three days and are not having to much lucke finding the problem. They think it is a oil pressure leak and can not find the leak . What do you think.

I think there blowing smoke in places you dont want it blown. If the check engine light was on then they have a good idea of where to look for the cause of the problem. I think there giving you the run around.

Most likely the code was for ICP above or below expected. The main cause is a leak in the high pressure oil system. If this is a small leak it can be hard to find somtimes. Yours is most likly a small leak since it didnt just die on you. This leak can be as simple as the fitting at the back of the pump(very common), an injector oring, or heavon forbid the branch tube itself which will involve removing the rear cover of the engine so it takes awhile. Hope its the fitting or the injectors or you may be out of a truck for a while

Yeah, I was going to say a leak in the HPOP or something to do with the oil system. But...sounds like big knows a little more about it than I do. So go with his answer...

Hey big, what is different in the motor in a light duty and med duty truck?
