Ford 7.3L Power Stroke (1999-2003) :: Oil Leak / Dripping At The Back And Bottom Of HPOP
Jul 21, 2015
Have 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've been having transmission fluid leak from my truck for a while now. Very slow leak. At first I thought it was a hard line and replaced it but it was still leaking. Then I think I found where it was coming from. It looks to be fluid dripping on the bottom of both sides of my intercooler? On both identical spots. I am guessing perhaps I had a crack on my transmission oil cooler and driving blew it into the fins of my intercooler. I took my old one off and couldn't visibly see one. I have a brand new trans cooler installed now. Haven't drove yet as I am waiting on brake parts? I couldn't think of anything else on why it would leak off the intercooler?

Do I have to remove my fuel filter and bowl to attempt a repair on my HPOP leak?

The 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?

have a f550 with a hpop res leak on the backside and wonder if this is in fact under any pressure when functioning since it has o rings on it as well.

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.

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?

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?

I have an oil leak under the flywheel cover that gets worse as it runs.It is dripping directly off the middle of pan below where the torque converter attaches and as i said it gets much worse when its running which makes me think rear main seal....

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.

Last 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?

Took the torque converter cover off and this is what I see. Before I took it off the cover looked oily. Prev I replaced the EGR valve and some other sensors and there was oil on top of the engine. Does this look like a rear main seal or oil dripping from the top of the engine?

2003 F250 7.3... I noticed a water leak dripping down onto passenger side front leaf spring. I saw this before but attributed it to the AC (which kicks butt) but haven't used the AC. No scent to the clear fluid, temps all look good. Running fine. Where does the AC discharge go? Could AC be on (not on AC but set in blue zone on dial)? Reservoir looks ok but could e small volume of drips.

I've got a late 99 7.3 truck that I just recently did a lot of work on. I installed a new turbo with bellowed up pipes and a new exhaust system and when I went to start it up it started leaking fuel in the back pretty badly. Initially I thought it was the banjo bolt or the passenger fuel line but looking at it more closely I realized that it's not coming from there. It's dripping all over the side of the starter and is collecting at the low point of the metal lines down below. I also saw small droplets coming out of the up pipe where it meets the manifold but it looked like nowhere near enough to produce the kind of leak I'm seeing, also I know fuel shouldn't be coming out of the up pipe to begin with. This is really annoying and I would like to drive my truck again.

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?....

Kind of bummed my truck now leaks oil from both the front and back. It's not much volume wise - probably a pint every couple months but before I came up to Alaska it had never leaked a drop. Probably nothing I can do about it barring a rebuild. I have noticed all the guys say not to use any oil additives of any kind. Trying to get it in a shape for another epic journey back down the Alcan highway this fall. Or should I get rid of it and go for a 6.7.

I have a 2000 Ford Excursion 4x4 7.3 with 230K miles, around 15,000 miles ago I replaced the transmission with a rebuilt 4R100, lately I have noticed a leak towards the back end where the transmission and the transfer case connects. Some of the bolts on the bottom of the pan have ATF on them, some others however do not. I have had to add a quart of ATF in the past couple of days in order for it to engage into drive when going from Park to Drive. I have to rev it before it actually kicks in. I'm hoping the leak is just being caused by a gasket either in the pan or connecting the trans to the transfer case..

I've never had a drop of fluid leak from my transmission until yesterday. I towed a very heavy trailer (10k or so with tons of tongue weight) about 300 miles and I got back and noticed a decent amount of fluid leaking. The transmission temperature never went over 160 on the drive. I know these transmissions tend to puke oil sometimes, but doesn't that only happen when they overheat, or would a very heavy trailer have the same symptom?
It appears the leak is coming from somewhere near the back of the pan around the gasket. More specifically, it seems the one bolt pictured below is leaking. All bolts are tight and the pan gasket was replaced about 6k ago with the last fluid flush.

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

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.

So 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?
