Ford 7.3L Power Stroke (1999-2003) :: A/C Leak Coming From Metal Tube Going Into Spongy Area
Jul 15, 2017
So after a hot drive yesterday we thought to do some googling about our clutch cycling on and off so fast. Yep, the airgap was out of spec. Fixed that.
Then we added some refrigerant to the truck. The truck is "new to us" and this is our first summer with it so not sure what might've gone on previously with the AC. Didn't take long to find a rather sizable leak. :P
See that metal tube going into the "spongy" area? Yeah, that's where it seems to be coming out. That tube is the only one that's cold, the rest are ambient temp. We fix a lot on our jeeps, but the AC system is naturally a bit out of our wheel house since it's not something you normally tangle with. Is this an easy fix? Or do we need to take it in to get serviced?

I had a leak at the flange several months ago. I fixed it with the diesel o rings kit. I made a trip from TX to AL with no leaking and drive it daily without leaks. But, 2 weeks ago noticed a small dribble of a leak from the same spot again - not enough to leave a mark on the pavement but any leaking drives me nuts. I applied some RTV. It worked for the 2 weeks.
Today, noticing another dribble of a leak coming through the RTV down the pan. I'm thinking the flange is bent and not keeping that o-ring sealed against the pan. I'm going to try to apply some additional RTV at the leak spot. If this doesn't work? Is that Strictly Diesel adapter really worth that kind of dough? Is pushing the OEM adapter into the pan really acceptable? Any other options?

I have a 2001 7.3 and have found the engine oil dipstick coming out of the dipstick tube by 6 - 8 inches on three different occasions. Did not think much of it until my other 2000 7.3 did the same thing.
What causes this as afraid it will come all the way out and get into the serpentine belt.

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 developed a sounds that sounds like metal on metal. Not a grinding but more of a "swish swish swish" light metal rubbing when the truck has been running a mile or two. I can barely hear it over the radio but its very noticeable when the window is down. It is not affected by the pressing the brakes and it gets louder and faster in direct portion to speed. It will occasionally leave and start right back up. I touched the front rim around the hub and it was hotter than I wanted to hold onto. It didn't burn but it was hot. It was 105 degrees that day. Here is what I have done.
I replaced that front hub in 2010 and probably have 50K miles on it. I did the 3-9 test and there was no noticeable play. I spun the hub and while it seems to spin ok it does seem a little dry.... I will pull it tomorrow and see what it looks like.
I pulled the calipers off and the brakes pads are at half way and there is no burnt smell. I spun the rotor and it seemed flat and straight. I do have a small tiny lip all the way around them on both sides but I figured that's normal with 265K. I pulled the pins and they were dry but they didn't seem to be sticking. I cleaned them up with the boots and am going to replace them when I get some brake grease tomorrow. I have not looked real hard at the caliper but I plan on pressing that with a C-Clamp tomorrow to check it. Since the rotors and pads looked OK, I assumed there was not a stuck caliper although haven't ruled it out. The axle behind the hub seem to spin freely before I removed all this stuff and the hubs are not locked.
I think I covered it all .. I also thought it could be a rock or stick but nothing came out of my caliper or rotor when I took them off ..

I am in the process of replacing my water pump. After I removed the pump, I found quite a bit of metal-on-metal wear between the impeller and the water pump housing. Is this common?
I've been running a coolant filter on my system for years now, so hopefully its been effective at collecting some of the metal that has clearly been worn away. Either that, or this is a sign that the filter isn't working at all!
I'm a little worried that the new pump will scrape the scars left from the old pump.

I found 2 Ford OEM part numbers for what seems to be the same identical metal CAC Tube for the drivers side.
6C3Z-6C640-AA
and
6C3Z-6C646-BA
I wanted to place an order today for my '06 but want to make sure it's the right one. What is going on here? (maybe one is for a '03-04) I Don't know...

So I've been getting a whining sound coming from the transmission area. I checked my transmission fluid and it's nice and pink so I checked my transfer case fluid… It came out like black watery gear oil! How bad is this? I am putting synthetic Dex/Merc back in it. It's got me a tiny bit concerned.

I have 1999 F350 7.3 Crew Cab 4WD. I took it on a 4 hours trip towing a trailer to haul a small tractor on it. after 3 hours of driving, I started hearing grinding and metal chewing sound coming from the front axle or close the wheel hubs. It was awful, terrible, ... you name it!!! I had to continue or I will lose the tractor I paid for already. The sound was coming for 1-2 seconds each 500 feet or so. It never stopped or changed. I pulled over to see what's going on and found the following:
1. Left shock is leaking badly
2. Right locking hub is gone (not sure if the truck had one before). I bought this truck last year, but I never had to use 4x4 and I know the 4x4 motor by the transfer case is missing and the nipple on the transfer case is set to the 2wd position so the front drive-shaft does not turn.
I took the front shock off and continued to drive without it, the noise did not go away.
I pulled over again and this time I noticed that the dust cover on each end of the front axle is missing too. I have never worked on these axles before, but I jacked one side, and sure enough, gear oil was leaking from the other side. I took the plug off the front differential and stuck my finger in it. I felt a creamy brown-greenish stuff in the differential. The consistency is like mayonnaise or thin peanut butter. I put the plug back on and went to pick up the tractor because I did not want to miss it fooling around with the truck on the highway.
The truck made it there and back (almost 5 hours total after the break down). The sound never stopped every 500 to 1000 ft.
After getting home safely, I took the other locking hub off, and took it for a test drive. I did not hear the noise, but now my right brakes are locking.
I took of the wheels and saw that the retaining snap ring (C clip) for the front axle on the right side came off by hand. I took the washers behind it off. Took the calipers and brackets off. I have never done front axle rebuild. I am not sure what has been damaged and what's still good.
Right of the bat, I know, at least, I need 2 shocks, one brake caliper and pads.
My questions are:
1. Is it possible to take the front axles off on both sides and make it 2wd for now until I have the money to rebuild the axle?
2. Could I use the same hubs? or they are most likely damaged and how to tell?
3. How to tell if the differential is damaged/needs rebuilding?
4. How to tell if the axles/spindles are damaged?
5. Is there a step by step tutorial to rebuild the axle with all seals, bearings, ...etc? How hard is the job for a hobbyist? I do most of my repairs myself, and I was lucky at 36 years old, I never had to rebuild a differential.
6. What else I might have damaged in the process of driving it that long with the noise? How do I tell if I did?

Getting the RV ready to go for the summer, and no a/c. I started to add freon, and found the leak right away.
It's on the 3/4" pipe that goes right over the upper radiator hose; obviously rubbing metal to metal caused the pinhole. Now I know where that mystery green snot came from all over my radiator hose coming back from Yellowstone last fall.
First thought was to replace the entire pipe. There's an easy threaded connector on the upper end, but way down on the compressor is a strange fitting that looks like a triangle stuck against a cube. I can't see how I'd get a wrench in there very easy anyway. What is that fitting?
I bought a Dorman 3/4" repair kit, but until it arrives in the mail I don't know if I've got enough straight pipe to work with. Do I need to add oil as well as freon once I charge the system again?

I have just acquired a 2011 F350, 6.7, SRW, 4X4, Long Bed, Super Cab with 125K on the clock.
It has an oil leak, not real serious but messy, that seems to be coming from an area above the starter. What is up there that could leak besides the valve cover?
I know that the later super duties have required the removal of the cab for any work much beyond an oil change. I certainly hope that this not the case here.

I can take one finger and spin my steering wheel full left and right. There is no Resistance at all. Very scary to drive. Would it be the steering box. I am supposed to be at a military school tomorrow need to fix asap.

Thats the sound coming from I think the front left area and the rate is proportional to speed. It only occurs at slow speed from about 5 to 15 mph and it seems to only occur for about 30% of each rotation. I plan to jack it up and check tire wobble or if the sound occurs during free spin. Any other things to check?

I have 1997 F250 LD since i bough it has been doing this chirping sound coming from the serpentine belt and the pulley area but when the truck has been working for 15 - 20 min it goes away
This is apart from the from the problem before I think the fan clutch is broken because when I start the truck I can hear the fan going at the same speed of the engine is that normal ? even when the truck is cold

I had a leak coming from the top of the transmission. The antifreeze appears to be getting into the transmission because when I pull the stick it's a chocolate/white fluid and both the antifreeze and the transmission fluid are new. So, I am talking to two transmission places, trying to decide which one to go with and what to ask them to install because it seems I have different choices depending on what I want the truck to do. I will be using it to haul dirt and farm items, pull a 20 ft cargo hauler, maybe a rv some day.
The transmission guys are throwing all kinds of lingo out there I don't understand. and the price is anywhere from 2500 to 5000 for the tranny. Also they tell me what is included and what is to be changed out but I don't know if it's "everything". One guy said that the "John Woods" brand of tranny is what I want. Also I think my stock engine is fine. A cylinder contribution test shows only one with an issue and it seems to rev fine. The glow plugs need to be replaced I think. Where I'm getting here is if later I have to replace/rebuild the engine should I get a bigger tranny now?

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 am doing some maintenance and trying to replace my EBP tube and sensor. I luckily have the dual alternator package, so getting the tube in and out has been a pain to say the least. I can't for the life of me get the tube back into place. As always, a 20 minute job is taking me 2 days.

I've thought I smelt diesel fuel on an off for a while, but never found the source.
Tonight, 17 degrees out I have fuel in the valley and it appears as if the back of the drain valve is wet.
A fuel bowl rebuild is on the short list. Is this typical, the cold weather brings the issue to light?

The dipstick tube flange is now leaking ....

I've had a shifter-related short on my instrument panel and stereo lights for close to two years now, and it finally got so bad I had to dig in and decided to proactively replace the shift tube while I was digging in. After all, the existing one had 290K miles on it. Although the lighting issue drove me to replace the shifter tube in hopes of finding a damaged wire, but this issue has now been moved to a separate thread [URL] ...... The remainder of this thread deals with my difficulty with the new hardware.
So, I compiled all the info I could find on replacing the shifter tube and did the replacement on Saturday (Dorman shifter tube kit from O-Reilly's). The Dorman kit was fine, mechanically, and the parts fit together well. I did, however, have to smooth out some burrs and sharp machining edges where the new nylon bushings go just to prevent premature wear on them from the sub par machining cleanup a the Dorman manufacturer. I also inspected all of the wiring harnesses and connectors carefully, but could not find any evidence of a shorted wire anywhere.
Results... Shifter Movement: Overall, the shift movements are much more secure and smooth as butter, even though the shift arm itself still has slop in it where it gets pinned into the tube housing.
Now that it's all together, though, I can no longer shift down into 1st gear, and getting it into Park to release the key is tedious. I uninstalled and reinstalled the rear shifter bracket three times (the one which is typically related to not being able to get into Park and 1st). I carefully made sure that it was tight and completely flat against the rear of the shift tube each time. I just cannot tell why getting into Park is tougher than it used to be, nor can I find a physical barrier preventing it from getting it into the 1st gear position.
So here are my questions:
1. The steering column mounting flanges have some adjustment slop around the two rear mounting bolts, and the front two bolts also have minimal "adjustment" capability. Is ti possible that my entire shift positioning problem is due to not having the steering column physically mounted in the right alignment and that is restricting motion on the gear shift flex shaft?
2. If the answer to #1 above is "no", then what else do I need to be looking for to resolve this limited shifter movement?
3. There is a solenoid switch at the rear of the shift tube... is it possible that this is going out? I honestly do not suspect it because I have no trouble starting the truck when in Park, but I have not yet verified the effect of being in "R" on whether or not my backup lights come on.

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?
