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?
New to me early 99 (4/98) f350 7.3 6 speed. Truck started acting up a few days after I bought it. Return line at fuel bowl was leaking, so started there and found a bad seal on the Fpr (unrelated to the fuel leak due to disentegrated compression sleeve). Fast forward through a bunch of parts swapping that still resulted in miserable lift pump pressure readings, I pull the sending unit out of the tank, expecting to find a plugged screen.
Well, there was in fact a plugged screen... Attached to the bottom of an in-tank pump. How did that get there?!? Everything I've read says there should only be a pickup tube??? Should I get a new sending unit from a junkyard and do the hutch mod or???
I have a 2001 f250 7.3l 4x4 and the fuel filter housing is leaking real bad from either the back or under it. I need to get info on parts that i would need as well.

The fuel line on the passenger side under the turbo that leads to the head is leaking looks like from rubbing on the pedestal, anyone ever just cut it and throw in some fuel line and hose clamps?
View 14 RepliesInitially had indications of a leak under the wheel arch on the drivers side.
About 3-4 months back replaced both PS lines and the leak stopped - briefly (maybe a couple a weeks).
Now the leak is back, but what's interesting is I lose more ATF fluid on a single long haul run than I do running round town for 3 weeks. I can't work out where the leak is coming from to identify what else to replace - short of just buying a pump and reservoir and replacing them as I've already done the hoses.
My turbo cooler pipe was hard up against the old PS pipe where it entered the side of the reservoir until I did the replacement hoses. Now I have it out the way but I'm wondering if it's caused some unseen wear or damage.
If I just do the pump to see if that works are the reman units any good out of Autozone or O'reilly's?
I've had my early 99 f350 7.3L for a lil while now. Starting to see few problems surfacing. while doing my weekly fluid levels found oil in coolant and after looking around found oil covering bottom of driver side engine. As far as i can see it looks like oil cooler leaking from front side.. Should i just replace oil cooler or rebuild?
View 4 RepliesI 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.
I had a fuel starvation problem because Ford painted the inside of the fuel tank and the paint was coming off and clogging the filters and because I foolishly drove it I now have white smoke spewing out of the tail pipe and an engine miss.
I also explained that I thought that the white smoke did not smell sweet like antifreeze, but rather like diesel. (Hoping that a head gasket replacement is not required.)
I am in the middle of doing the Hutch Mod with frame-mounted Racor PS120-2 jar-type screen pre-pump filter and shortening my previous Harpoon Mod and paint stripping and powerwashing the inside of my tank. Next I plan to move on toward the engine issue.
This evening I was under the van with a flashlight and I noticed that there was a black liquid of some sort at the driver's side exhaust manifold where it joins the up-pipe. At first I was afraid to touch it fearing that it would be carbon-sooted water, but it felt and tasted like carbon-sooted diesel.
And since I haven't started the engine in two weeks and it has been routinely near or over 100F in Sacramento, water would have likely evaporated days ago.
Does it make sense if the fuel starvation problem caused an injector nozzle or its cup to crack or to stick open or to otherwise spew unburnt fuel into the exhaust manifold which would cause the white smoke? Obviously, the unburnt fuel must get from the affected cylinder(s) to the tail pipe somehow, which likely means out the exhaust valve, through the exhaust manifold to the up-pipe and through the turbo to the exhaust pipe and finally to the tail pipe.
See pictures at my CP. I can't figure out how to attach them or put them inline here because it still says I can't do attachments.
What is my next move? Remove the driver's side valve cover? If so, what should I look for, etc.?

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.

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?
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 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....
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?
View 14 RepliesI 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 ....
View 7 RepliesI've just finished a marathon replacing the y-pipe, and doing the IPR screen. I had many seized/stripped bolts to contend with. 2 I had to cut off in the most awkward places.. Anyways, it all came together and completed the project late tonight...
Befoer even starting the truck I noticed coolant dripping from passenger side manifold/block heater area.. I obviously must have damaged something in my reefing on turbo to get it lined up with exhaust pipes, etc...
I cannot see the source of the leak, but it seems wet above the block heater, but pools there then drips.. I'm curious where to look. Could I have damaged the EGR cooler and its coming from there? At the manifold joint closest to the back, is there coolant flowing there? I am pretty frustrated, because after going through a day like to day, ripping my arms to shreds, straining for 12 hours straight, then having yet another issue to figure out...
Also this is as best as I could get the y-pipe to meet the turbo... slight gap at bottom.
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.
View 12 RepliesWhat I know the truck was running normal except if I stomped the gas pedal and let off it would not respond again until I shut off keys and restarted this was a month ago now the truck sounds like it has a lope tune.
When I hit the gas pedal it blows white smoke and if I press the gas while idling or driving it floods out I did the spray bottle test on manifolds the drivers side was plenty hot the passenger side is cold you literally can touch while it's running.
The truck sounds like it's only running on 4 cylinders it has gotten so bad I parked the truck. Also this truck always had poor mpg 8 to be exact city hwy and towing nothing changed the mpg at all it used to blow out wet soot that would fall down on the truck and anyone standing near it.

We just replaced the #5 injector. Went to take for a test drive and the 4 glow plug caps on passenger side popped off and leaking oil while driving. Pushed them back on and they popped off again. They shouldn't be under pressure should they.
View 6 Replies99 f150 4.6 4x4 ... auto.. so, driving on the interstate I had to accelerate hard to avoid hitting a crazy driver... after that I smell antifreeze... get home can't find a leak.. wait a bit and I see antifreeze leaking passengers side coming down the firewall outside... if you are laying behind the passengers front tire with your feet to the back tire.. looking up you see the catalytic converter.. behind that on the firewall a stream of antifreeze... follow the stream up and there is a piece of plastic just about were the firewall starts to go straight up from the floorboard bend.. putting my hands in that it goes inside..and its wet inside..
I can't tell what that's for really but. Am I guessing evap coils access? any rate. I don't feel any dampness inside yet.. but I do smell it in the cab stronger now. I haven't ripped up the carpet either. Im suspecting my heater core sprung a leak?? there is a good amount of fluid coming out and down the firewall outside I would say I have about a 6-foot puddle now. course I parked on a hill too. no fluid that I can tell is at all leaking off the heater core hoses.. they felt dry. Im guessing there is a drain port in that black box inside and that is where this is coming out?? no noticeable leak from the motor side.. it's all dry.. its actually going down the firewall and hitting a metal plate that carries out to a cross member on the transmission and then leaking down.. motor area is dry.
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.
