I have used this forum to look up everything I've needed to since I bought my 05 F250 FX4 6.0 brand new. I have never had to post before because I always found the answer I was searching for. I'm hoping you guys can help me with my latest issue:

I was pulling our brand new camper in 100* heat. I began to hear a clicking from the truck from the engine compartment that would be right by the turbo. My engine started overheating, but I had no smoke (black or white). The engine cooled down after I was done climbing the hills, but I had feathering from by the air cleaner and the clicking/chirping was still present.

I pulled over to let the truck cool and checked my coolant reservoir. While pulling over, I lost accelerator pedal responsiveness. The turbo was also engaging a lot. I pulled over. Put the truck in park, but left it idling. As I was looking around under the hood, the truck died. I have not been able to start it. (This all happened Saturday). The truck is 20 miles from home, and I've been out tinkering every day. Here is what I know:

1) I have 48 volts to the FICM.
2) I have tried to start it early in the morning and in the evening when temperatures were low.
3) When I crank, I do get oil pressure from the instrument cluster.
4) The oil level is at the correct markings on the dip stick.
5) Using my scanguage II, I have verified an IPR reading of 14.8. As I crank, it goes up to 84.7. My ICP reading is all over the place. It always gets to above 500, yet it with the key off - engine off, I get a reading higher than zero. With the key-on I go from 300 to 500 and to over 1000 with out the think even hinting at starting.
6) I have oil in the oil filter housing.
7) I have fuel in the upper fuel filter housing bowl.
8)The batteries and alternator have all passed load testing.
9)I tried to start the truck with the ICP disconnected, and didn't have any luck.
10) I have no codes set or pending.

I am at a loss. I don't want to start throwing $$ at various parts. Any help would be greatly appreciated.

 

Have you ever replaced the standpipes, dummy plugs or STC fitting? You definitely have a HPO leak, likely on one or all of the items mentioned.

 

I haven't not replaced those items yet. Should I start there? I'm just hoping it is not the HPOP.

 

Is there anything else I should do while I have all of that torn up?

 

It would probably be a good idea to do an air test on the high pressure oil system to help pin point where your leak is...but it would be a good idea to change out said parts above regardless. They aren't all that expensive and are known to fail so unless you like being stuck on the side of the road I would go ahead and switch them out. The pumps are pretty stout on the 05's and up so for the time being and until you can do an air test let's assume your pump is ok. Leaks can also occur at the tops of the injectors also. It would be worth pulling the ipr valve and make sure the screen is in tact and nothing is holding the valve open.
