6.0 problems and code???
Well on my way back from the mountains this afternoon with the family stop to refuel and pop hood and noticed the degas bottle had puked...Got back on the highway drove another 60 miles and rechecked and ithad puked again big time... Drove it home a total of 200 miles and the bottle was empty...
Borrowed my buddies scan tool and got code p0528 (Fan signal mal) I also ran the data stream while driving about 12 miles and got ECT 201 and EOT 258.. Seems like its way off the recommended 25 degree variance..
Any thoughts?? would a faulty Fan code(p0528) cause this...
Cant understand how it would since the coolant temp is within parameters.. Would the fan somehow cool the oil cooler???
Any help would be appreciated.. Thank you

Thats way over it should be no more 15 degs apart not 25.Most likely your EGR cooler is gone that's were your puking is coming from.Do you have the latest flash on your truck

refer to tsb 09-08-03 for the correct information.
yes the cooling fan effects the oil temp. you need a new fan clutch.
odds are you need a new oil cooler. and maybe even some head gaskets.
I would recomend that you do bench test the egr cooler however

Cheezit.. I am showing no signs of a Headgasket leak.. No smoke(Whats so ever), Coolant is golden clear and never seems to overheats according to gauge and scanner...Drove it hard on the return 12 mile trip.. coolant temp never passed 201 but oil temp went to 258...(Ambient temp was 86*F) I did remove and clean egr valve two weeks ago and noticed that it was clean and dry(powdery).. even parked the truck on a very steep incline to see if coolant was visible perfectly dry...
also how could the fan being bad effect the oil temp even though the coolant temp stay low???
Thanks in advance

head gaskets as a 99% rule dont cause smoke. in reality its more a head bolt issue then a gasket issue.
look at were the temp sensors are.
ect is in the front cover
eot is in the oil cooler
a restriction in the coolant side of the oil cooler will drive eot.
a fan that does not know how fast it is going will change every aspect of how the enigne trys to cool itself.

Cheezit.. Should I actually hear the fan come on.. because to be honest I have never heard the fan... I see it moving... But don't feel air moving or hear anything...
Also want to point out on the way up to the mountains it was raining and in the 55-58*F and there was no puking... If we were leaning toward head gaskets shouldnt it puke regardless of ambient temp.. Considering boost and running pressure would float the heads
Also will be taking it to dealer first thing in the morning.. Should I tell them all the diagnostics I have done and will this repair be covered by my premium care warranty.. thanks again

the dealer will do all the diag themselfs. puking can be caused by a restriction in the oil cooler, egr cooler and or head bolts

Cheezit: Tw here, sent you one about two weeks ago on a HPOP. I bit the bullit and dove into it and changed the HPOP. I finished putting the thing back together arround 1:00 pm, fired it up (first time since I have owned it), let it idle for an hour, to work the air out. shut it off, let it cool for an hour, to let the coolent stabilize. Fired it up again, sounded good, took it for a ride, got to the end of the block, towed it back with a chain. code says crank sensor. How do I fix this? 2003 F250- 6.0

you can try a crank sensor. but they almost never go bad. Most of the time its in the main engine harness. Odds are you will never find it either. So at the shop once we know were it is for sure you get a harness.
look at the bright side. it runs now

Cheezit: What are the torque specs for the Hpop base and discharge tube? 2003- 6.0, in inch pounds. which o-ring goes on the hpop where the discharge tube bolts on? three came in the kit, I presumed it was the skinny one.

if you are not getting a freq reading from the sensor then you have an issue. were are you taking the reading from. if at the pcm then I would suggest doing the same at the sensor.

chased it back to the ipr, pulled the ipr, it has three holes in the screen and stuck open. could this give a false code reading? Also do i need to change the hpop again? nothing was found on the supply side to account for the holes in the ipr screen. put an ipr for an 06, into an 03, the reason for the screen, worked fine until it quit. If the hpop came apart, what about the rails?
