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 RepliesWhat are the hose lengths for the 2 HPOP and cylinder head oil crossover line? How about what size oring boss fittings you need into the head?
View 1 RepliesIn my motor build I'm replacing the HPOP fittings in the head. Do these need any sort of thread locker to secure?

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?
After 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'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?
How 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?
View 10 RepliesLike the title says I dropped about a 2 inch piece of small washer fluid hose in my cylinder while evacuating the oil from it . Will it damage the valves If I ran it? Any way to remove it without removing the head?
View 14 RepliesIs this job worth doing as a preventative maintenance item? I replaced the rear fuel rail plug (aka banjo bolt) o-rings because they were very easy to get to with the up-pipes out. But the cylinder head plug in the rear is pretty high up and even with the up-pipes out, there isn't enough room to get a breaker in there that's long enough and has enough movement to loosen it. The front would be easier to get to, but both accessory brackets need to come off to get to them on both sides.
As far as I know, none of them leak but they're all 17 years old... BTW in case you haven't been following, I'm doing up-pipes, injectors, turbo, rebuilt HPOP & fuel bowl, boots & clamps, etc. so I'm trying to knock out any PM items while I have it apart.
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 Replies2005 PSD 6.0L Excursion ... I suspect that have a fuel leak at the fuel line fittings near the driver side cylinder head. (I believe that it is fuel, since it is so clear, I guess I should collect a few drops and see if it burns vs. coolant.)
It appears to be at the junction of the fuel lines. This is the point where the fluid drops off the tubing and falls down. The clip that holds the two tubes together at the joint is very dirty, the one below them is clean. The tag on the line that is at the joint leaking is part number 3c34-9j338-ag. Is there a o-ring in side the joint? Do I need to replace both hoses of the joint? I can't find any posting of a history of this fuel line leaking.
Or... is it that the joint never fail, and the leak is up tube? I can't see any where it is coming out when viewing it from the top.
I did the extended seal kit and non-serviceable plug on my HPOP and now the CEL is on. It is throwing the below codes. The truck in all reality runs fine and even a little better on a cold start than before resealing, just the CEL is on.
P1280
P1209
P1282
P1212
P1211
I cleaned the IPR when it was out when I put new seals on it but could it go bad by just taking it apart? The ICP and IPR are definitely plugged in. The truck is all stock, no chips.
I started "Hard Start at Operating Temperature" you can probably tell that 300k has done a number on my HPOP. I'm wondering what to do... do I buy a new pump from ford? Buy from ebay? Or is there a good pump rebuilder in the Portland metro area? I've heard they are almost impossible to rebuild.
View 6 RepliesSo I have a 2002 7.3 Excursion and I think it is low on power. ICP is falling on its face when on a 60 or 80 HP tune. I have some boost leaks at the plenums and will work on that but that shouldn't cause my ICP to tank at full throttle. Following are some numbers I pulled with WOT runs up a 6% grade.
16PSI BOOST
EXHAUST PRESSURE 40
ICP 1900
80%IPRDC
this is with the 60 or 80HP tune on my DP-tuner. If I ease into the throttle I get
2700 ICP with
45%IPRDC
but if I stomp on the throttle it stumbles and ICP tanks.
Running the stock tune I can maintain
2700ICP at
40-45%IPRDC
Is this my HPOP being weak, or worn out injectors, to much of a tune or a combo of all three?
Pulled the HPOP reseal an oring that was leaking oil. Feel confident that I made sure the check ball stayed in place. Torqued the bolt to 96 ft lbs. Have fuel in the bowl.
We have cycled the starter about 20 times for 15 to 20 seconds. Batteries are charged.
Here is what the AE scan tool is saying after a few seconds of cranking:
ICP -160
IPR - 0.43
Duty - 63.67
Do I need to get a different reading/test.
I have read about stuck open IPR valve giving the low pressure problem, but the truck was running prior to pulling the HPOP.
Lets say I left out the check ball. Would the scan tool show 0 pressure? (Trying to rule out the check ball)
How about if I didn't get the spring seated in the high pressure oil fitting and instead it is hung on the threads and is compressed inside the HPOP. Could that be the case?
Not for sure it makes a difference, but the truck did fire off once on Ether for second.
I have a 7.3 and I think it's leaking oil out of the HPOP but I'm really not positive.
View 2 RepliesWell my hpop is cracked and leaking alot I need to get home this sucks I must of tighted it too hard
View 14 RepliesThis started out as a turbo pedestal O-ring change (leak down the back of the engine). Since I was going to take everything out to do that I figured I'd reseal the fuel bowl and hpop. Wound up replacing the up-pipes as well. Went ahead and changed the ICP and CPS. The truck started rather easy as I've heard its hard to get the air out. I drove it about ten minutes and then noticed it was leaking oil so I went back to check it. I found that it was leaking from one of the output fittings on the hpop as I guess when I tightened it back up after putting on new orings I damaged the pump by over tightening.
The oring and fitting were fine it was on the pump threads I guess. Anyway trucks got 280k miles so I just bought a new hpop from the stealership. Went home and installed it and the truck won't start. Pulled ICP out and cranked no oil coming out. The only other thing would be ipr (I cleaned with brake cleaner and air tip before putting in the new pump) so just to know for sure I bought a new IPR from the stealership and still NO Start. I didn't fool with anything else don't know what it could be. I checked the bolt in the front cover (tight), got to be a BAD (new) pump right.
