Ford 7.3L Power Stroke (1999-2003) :: Leak Under Passenger Side?
Nov 6, 2015
I moved my truck before I noticed exactly where it was coming from then after ward looked in the engine compartment. I had a puddle under the passenger side looks like the hoses going into the passenger glove box area (because I saw a few drops on them). The liquid is silvery. Any guess what fluid this is or where it might be leaking.
The antifreeze doesn't seem to be getting lower. I drove it yesterday for about 30 minutes and no crazy leaks.

2003 7.3 175,000 miles...
Saw a stain in my driveway where you normally see AC drip. Opened hood and saw degas empty.
Looking around like crazy and find wet area. Where the coolant line turns down beside the passenger fender.
Looks wet near bend going toward running board. Didn't get to inspect much but I pulled back a bit of loom to inspect shape of lines and they look great.
What could be going on?

My 7.3 has a leak on the front diff passenger side. It went into a shop for repair and they did both seal but the passenger side came out with a worse leak than it went in with. So just looked this morning and small pool of oil under the ujoint area on the concrete. Its booked in again to be fixed under warranty repair (place that fixed it, repair came with 2yr warranty) on Wednesday next week - was the earliest I could get.
Question - can i keep driving the truck? I'm making a wild assumption that I can unless I use 4 wheel drive. My intention was to just keep topping up the diff to ensure there is fluid in it. It's the work truck so wouldn't be good to be without....

I just finished installing a new turbo (shaft play and lots of oil in the compressor side), RR up-pipes, and T500 (250k and once had a very long crank to get the ICP up to start).
Anyway, except for another exhaust leak at the pass side up-pipe to manifold, it seemed to run okay but with lots of white smoke. I only have about 50 miles after the install, when it suddenly starting surging and made a lot of loud knocking noises. This then went away and came back again rather quickly. I was close to home, so I made back under power. I also received the two codes listed. My IPR is original, but two summers ago I installed the IPR re-seal kit. Everything on the IPR looked good when it came off for the T500.
After reading around, I saw that low fuel pressure / air in fuel can cause problems. I connected a pressure gauge to the pre-filter port on the filter housing, and got 40psi at idle. I then took a diesel shower and blew out the fuel line into the tank. After re-connecting it, the fuel pressure stayed the same but the engines idles much better, but still has blue smoke. It's the original fuel pump (to me anyway) and original fuel line connections.
I have about 3/4 tank, and no place to put it, so I'd need to run it out for the Hutch mod, or least to get in there and inspect. Would eliminating the Ford connections at the pump be worthwhile for now, and is 40psi at idle adequate? Wondering if it's time for a fuel pump?

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.

Small oil leak looks like coming down by drivers side up pipe. I don't think it's the turbo o rings. Better not be. But could be I guess. Anyways. It runs down somewhere by the up pipe down onto transmission. I'm not loosing tremendous oil or anything.

I have a '02 7.3 that has developed a severe oil leak in what seems to be a small line that runs from the drivers side head to the HPOP on the passengers side.
it seems to be leaking at the braket that secures it to the head on the drivers side.
what is this line called and where can i find one A.S.A.P?

It is still a drip, but is getting worse, for several weeks. May be power steering fluid. I have not found the source. I think it is after the truck has run and has fluids operating under pressure.

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'm having a problem trying to locate what I assume is an oil leak. It is on the driver side and the whole engine compartment is wet on the side up on firewall beneath the master cylinder. And the whole underneath is wet also axles and leaf spring and can't find where it's coming from. I have sprayed it down with degreaser to try to pin point the leak still no luck. Truck has 236k on it also new hpop and turbo pedestal and checked the valley and its dry. Right now I'm at a loss. I'm leaning towards oil cooler but would a leaking oil cooler cause whole side of engine compartment to be covered?

My passenger side wheel bearing is going out. I had a local company replace it under extended warranty 7 years and 90k miles back. I think I have gotten pretty good life out of it. I think it was from Napa but not positive. I try to grease then once a year but I'm not always successful.

Cleaned the truck today & noticed that the carpet in the passenger side footwell was wet, not real bad but wet at the edge by the trim, when I peeled up the trim the channel was full of clean water so I know it's not the heater.
I'm guessing that it may be a blocked drain but won't have time to check for another week, we did have some pretty bad rain last week so maybe it was just too severe for the drain to cope?
I should have taken the pic before I dried it up but the channel between the carpet & the door rubber was pretty much full
There is a mark where the water has run down the floor. Just to the left of the red antenna cable, I pulled out the glove box but couldn't see anywhere obvious that it has got in.

2003 Excursion 7.3
There is fuel leaking from somewhere on the passenger side of the engine.
What things should I be looking for? I'm thinking injector? Is it easy to identify and replace?

My passenger side braided line from the HPOP to the passenger head decided to rupture. Got 300k on the clock so that recommended 100k change interval is on the low side. Do I need the 'special tool' to remove the line from the HPOP and what is the current recommendation on a replacement line?

I have a Stock 02 f350 7.3 with 66,000 miles ... I'm sure this has been covered plenty if times, but I notice more so on cold days (-20 to 30). My truck after starting and even letting it warm up for a period of time makes a hissing sound from the passenger side of the cab near the dash/glove box area, Like I said I've only really noticed it on cold days ... It usually occurs between 1200 and 1800 rpm and it's a very touchy noise, for example I only really hear it when I'm cruising at a consistent speed, if I get on the gas a little it goes away till I bring it back to consistent throttle cruising then it comes back, same goes for when I let off the gas it goes away until I give it a steady consistent throttle again ....

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.

I have a small coolant leak coming from the passenger side near the back of the engine that forms a spot about the size of a dinner plate if it sits for a few days.
One thing I noticed is if I turn off the AC selector switch when I park I will get the drip but if I leave the switch on MAX AC when I shut the truck off I do not get any leaking.
It is definitely coolant and not just the condensation from use of the AC. If I haven't used the truck for a few days or if I have run it with the AC off I will get the drips.
If I run with the AC on and leave the switch in the on position when I shut the truck off it won't leak. I have tried to locate it from looking above and below but can't determine where it is coming from.

I just see a fluid by the front passenger tire leak when the diesel is running and ac is on.There was fluid up by both aluminum lines going into a plastic canister in the engine compartment on the passenger side.I couldn't find any cracks in the hoses or aluminum lines..The plastic canister I believe is (AC ACCUMULATOR ) did have a hiss of air when I shut the truck off. I can't see where the clear liquid is coming from. Just started to leak by the front passenger tire.

I have a 03 F-350, 7.3L. There is a slow oil leak that only leaks after I've run the truck. In other words, it doesn't just sit and leak overnight. I'll park it after running, and the next morning I'll notice a small pool of oil, approximately 2" in diameter. The leak appears to be coming from the oil pan area. I degreased the entire oil pan area to get a better visual of where the leak is coming from. I can see oil trailing down the front of the oil pan and the rear of the oil pan. Does this sound like the gasket? Or, what else could it be? I'm praying its not as bad as I think and need to replace the gasket.

This was briefly discussed as part of another thread. It appears that I have a boost leak when I hit roughly 24.5 psi. The leak seems to stay for a few minutes after showing itself, but then I'm able to produce boosts up to 24.5 again. For example, on my 20-mile/30-minute drive to work, I can make this leak "appear" four or five times, maybe more if I try. Does this self-healing leak ring a bell? I haven't done a boost leak test yet, but I'm leaning towards the RTV sealant at the OEM plenums due to the self-healing attribute.
To add a little info to this thread, I recently installed an S&B intake, 4" exhaust, bellowed up-pipes, RR billet wheel, RR CAC intercooler boot kit with new clamps, RDP reinforcing plenum inserts, AIH delete plug, and I removed the wastegate solenoid along with the red and green tubes. I don't have any gauges, but I recently began monitoring the boost using FORScan. Before all of this, I don't think I was producing enough boost to cause this leak, and I had no way to monitor for this leak.

Brothers of fte. I reach out. Tonight it appears I had a fuel bomb under the hood.
I've been chasing a fuel leak. Replaced fuel drain orings but one screw seemed to not snug up. Also the plastic was so brittle I couldn't replace the inner oring. Installed new valve worked great. A week later noticed new slow drips. Replaced fuel filter. Again good for two weeks.
Tonight pulled into the driveway hopped out immediately smelled diesel. Steaming from under hood. Popped the hood and everything was wet. Moved her to the street and it clattered like I was running out of fuel. Still half a tank though. Hosed of the drive. Popped hood again fired it up easily. Started fine. No noticeable leak. But everything is wet from fuel. Insulation on hood was saturated. When I open the hood fuel ran out of the insulation into the air intake. Batteries were wet!
Alright what gives? Do I have to be under load to see this leak?
