Ford 7.3L Power Stroke (1999-2003) :: Leak On Front Differential Passenger Side
Sep 23, 2016
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....

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 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?

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?

I am on the fence with getting rid of my 7.3. Here's why. Whenever I crawl underneath the truck or look under the hood I see all these different oil/fluid leaks. She has less than 200k miles and I use her to tow my boat to go fishing.
Right now I am trying to weigh if the truck is worth keeping or selling and then getting a new/newer truck.
Here are some leaks. One is obviously oil and coming from what I guess is the front main seal. I really don't know. The other leaks going onto the U-joint look like oil leaking down the axle from the front differential.
I'm growing a business and not sure if I have time to play mechanic. However, everyone I talk to always exclaims, "You got a 7.3?! You luck SOB!" and I am kinda getting the feeling letting her go would be a mistake. FWIW, she is paid off.
Other than a slight wobble in the steering wheel at speed, she runs like a hoss.

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 developed an oil leak from the bottom of the front crank shaft (front of the motor). How hard of a repair is this? any links to any tutorials? Should I even try this myself? Any special tools required?

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.

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.

My '02 F150 just developed an oil leak. It appears to be coming from the passenger side front. I'm just assuming here, but could it more than likely be the timing cover? I'm 150 miles from home and I'm debating on getting the timing cover gasket on my way home tomorrow. Also, if it is the timing cover, what other gaskets should I replace? Pretty sure the water pump oring.

I have a f150 with a 5.4L with 354,000 miles on it. It started leaking water somewhere on the front of the motor on the passenger side. it looks like it is under where the heater hose connects to the intake. I guess my question is can the water eat a hole in the intake?

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?

2003 Limited 6.0 130K. Just took a 1000 mile trip for spring break. While away, I noticed a small leak near the front passenger side of the truck. It is red so I assumed it was transmission fluid. It is leaking from, the best I can describe, a small housing that looks like it might be a filter near the tire (it looks like the old style canister oil filter housings). All the hoses are clean and where the hoses go into the radiator are clean. Is this an easy fix? I am a bit worried about trying to get the thing off without damaging the hoses.
