My 03' 6.0l hpop only makes about 1700 psi at wot, at hot idle the ipr is 25.1 and the icp is about 580. It runs pretty good but it seems the crank time to start is getting a little longer sometimes, other times it fires right up. It makes no difference if its hot or cold. Do pumps get weak or do you think I have a leak?....
View 1 Replies2003 f350 6.0. Ran last night and wont start today. Monitor says 85 psi pressure, should be atleast 500 to start. Could it be the IPR?
View 4 RepliesFinally got the hpop in my 03 done, got it fired up and runs great. The longer crank times seem to be getting better, however I am a bit concerned when I really get into her I am seeing pressures of 3400 psi......seems high to me. I guess I don't know for sure what the IPR was reading, will have to check that. Truck runs great, nice and smooth, but I am afraid I am going to blow something.
What is normal and what is not? Is there a way this pump will dump excessive pressures if needed? Or is it just a matter of time before I blow an oring out somewhere? I'm not sure how much the pump is capable of putting out. At idle it's sitting right around 630 after warmed up, maybe a bit lower.
Truck has a high oil pressure leak, only leak i have found is in the high pressure rail, I cannot get to it till sat, or sunday. So I have to let the oil cool before I can start. Any way testing to find the right temp for Oil to thicken enough to Build? I've been here for hours and its went from 180's to about 100 now...
View 3 RepliesI have a High pressure oil leak somewhere, and where it can be. I tore the oil rails out and replaced the nipple cup seals last night. I got it all back together and air tested it and sure enough a leak is present. I have no problem paying for your time (I always provide good beer). I can rebuild gas motors all day long, but these diesels has me thrown for a loop. The frustration I am experiencing is crazy at this point. All the injectors are new, and the dummy plugs and standpipes were replaced as well.
View 11 RepliesJust replaced the hpop on my 04' 6.0. It had been down for about a year because my low pressure oil light would come on after warm up. Truck ran PERFECT, but dam light would come on. Eventually it wouldn't start by cranking, but would on a bump. (I have a 6spd.) still ran good. I would never run it over 5 minutes because i didn't want to damage anything. Finally getting around to fix it.
After a day of air testing, we tracked it down to hpop. (air coming out of turbo drain tube). I had a hunch that the dam bb on pump had spit out from similar stories on FTE, and thats what happened.
Replaced pump. (its an older style pump BTW, although i have a january 04 build and every ford parts guy said differently.) Put everything back together and now it runs terrible! We ran the truck for over 20 minutes and it didn't get better. I am afraid its gonna damage something to keep running it. My mechanic says 5 cylinders are misfiring and its something to do with the ficm or injector harness.... But, it ran perfect right before the hpop change???? Everything was double checked to make sure it wasn't something dumb.
I've been watching fluid build up on what I think is the hi-pressure line on the hydroboost. It appears to be originating at the coupling in the line because it is dry back at the unit.
Is there an o-ring or nylon washer in this fitting?
Can it be tightened?
Does the o-ring or washer need to be replaced?
Is it a sign of something else, like a build up of pressure in the line that is too high?
I currently have zero problems or noise coming from the steering or brake system.
05 excursion with 04 motor. 290k miles. Had a crank no start issue. Pressure tested hpop only got 450 pressure. So got a brand new on from ford. Also did standpipe, and dummy plugs. After forever and day of cranking truck fired up. Sounded great let it sit for 30 min. Took it out for ride, mile down the road lost all power. Alternator was bad, replaced that and battered just to be safe. Now truck won't fire and have zero pressure. Something that could of been tripped during power surge?
View 8 RepliesI just replaced my injector cups a month or so ago and also injectors with some lower mile injectors. but now 3 weeks later still not getting any pressure at icp. I have dead headed pump got 3k plus but when i block off ether head i get no pressure. i have pulled injectors and checked for orings and they are fine...
View 2 RepliesWhat's better good options on a upgraded HPOP? As of now I have a stocker, it's getting low on pressure when even on my 50hp setting.... Was looking at T500 and Adrenaline. Any others could recommend? I'll be doing injectors down the road here too.

View 6 RepliesThe leak drains into the first valley of the block. This is after a cleaning and about 300 miles driving. I thought it may be the IPR but, it's looking pretty dry:
Some more pics .....
The HPOP line fittings are dry too. Where else do there the HPOP's tend to dribble a leak of oil from?
I've found everything there is to know about disconnecting the high pressure oil STC line from the oil rail on the early 6.0's, but I can't find anything about reconnecting them. Do you simply press it back on? Should there be an audible "click"?
View 14 RepliesAfter cleaning entire valley on my 2001 f350 with 7.3 I have found what appears to be a small leak under the hpop drivers near the IPR. HPOP lines are clean and dry. Possible for IPR to leak at 120k miles and what will need to be done to fix.
View 2 RepliesHave another oil leak, just finished the pan flange gasket last weekend, made it 150 miles, now a new leak.
Took the spider out and everything on top, cleaned the valley up good, the fired the truck. HPO lines are good, but have a drip off the back and bottom of the HPOP, when I reach under it from the back, its right below the large 2 inch circle.
What this might be? was thinking possible orings somewhere under there where it seats, but its been 6 years since I replaced all the orings, don't remember exact layouts.
I have an oil leak where the HPOP hose attaches to the cylinder head. I have the removal tool for the hose. I assume I need a new fitting. What's the torque spec for this fitting, and any additional tips I need for doing this repair?
View 11 RepliesI'm having Hard start when Hot problems, starts fine when cold. It takes a couple of minutes of cranking for ICP numbers to hit 500.
So far I've replaced:
ICP sensor
IPR
Injector O-rings.
Still didn't fix the problem.
I also washed out the engine, and put uv dye in the oil, let it run, to find any external leaks, but I found nothing. I don't thing it's the HPOP, because it's able to sustain high ICP numbers when I hold down the throttle.
My next step was to remove the HPOP and replace all it's o-rings, but I assume since I don't see any leaks, the o-rings aren't the problem. Is there anything else to check, that could be causing low crank ICP numbers when hot?
A good friend of mine just bought a 2003 xlt with the 6.0 and has an oil leak at the HPOP cover as far as he can tell. Looking for a good write up that explains how to get to where we need to go. Also maybe a list of o-rings and gaskets that will be needed on the journey. Is there anything else that may need attention while we are in that deep. I have read about the SVT fitting but not sure what that is or where. The EGR has been deleted.
View 12 RepliesHow common is it for the hpop to leak from the round piece behind the pump next to the drain bolt? Its on a 2000 f350 7.3.
View 12 RepliesLast couple of days I've been chasing a small oil leak. Finally figured out it's coming from one of the hoses connected to the lower part of the hpop (hpop hose). Leak is coming from the fitting connected to the lower part of hpop. Do I need to replace the whole hose and fitting? Just the fitting? is there a replaceable washer or oring?
