Ford 7.3L Power Stroke (1999-2003) :: Engine Oil Leak From Both Front And Back
Mar 24, 2016
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.

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 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?

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've had a persistent diesel leak its gotten worse and I've found it. Its in the valley of the V. I've attached a photo of the part its the one with the plug off it.
What it is called and maybe the part number. The gray plug under the red wire.

As it says, I have a tick. It's not apparent at idle and increases with engine speed.
Just spent $570 having bellowed up-pipes installed and while a little quieter, the tick is still there. What else tends to go out on these things? Manifold(s) cracked, manifold gasket(s)? It's seen high EGT's quite a bit but not for longer than 20-25 seconds.

So I decided to start the year with fresh oil. Like the hundreds of oil changes before, i changed the filter and added new oil. Only this time, oil started to drip off the bottom of the Oil filter at an alarming rate, only when the engine was running.
I figured the filter didn't seal well, so I repeated the oil change process. nothing changed, still leaking.
It was really cold (-10 C) when I did the oil change, I mention this in case it is a contributing consideration.
My truck is a 2000.

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?

The truck is a 2002 F450 7.3 diesel with about 120k Miles.
While driving from 45-70Mph the truck engine stops for about 1 second and starts back up by itself. I thought the problem was the cps so I replaced it with a ford CPS. Today the problem still persists. The truck engine turns off and comes back on, the tach drops to 0 rpm and so does the speed.
The Check Engine Light comes on and so does the water in fuel light and so does the Check Gage light. After I turn off the truck and start it back up the truck does not show the lights.
I believe I found the issue, but can't look into it today. While I was moving some of the wires on the truck I found out that if I move the red/black bunch just a little bit the truck shuts off and comes back on when i let it go.

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?

I recently purchased my 2011 F250 Powerstroke a week ago today with 87000 miles on it. the dealer assured me they did all the maintenance on the truck before i was able to drive it home. I noticed on my dash that it kept popping up i needed to change oil soon.. so i got out to investigate and realized i was about a quart low on oil so i looked around more and am seeing that i have a leak coming from the back of the engine running down to the oil pan.. I have not noticed any on on the ground at all but what this leak is coming from...

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.

Was replacing my cracked and leaking charge air cooler pipe Friday evening and noticed oil all over the place at the lower front of the engine. It has been a few months since I've been under the truck. No drips on the ground so it must be a slow leak while driving. Oil level is fine so it hasn't been leaking for long.
Any ideas from this limited two picture view? Front main seal? I've been reading the vacuum pump leaks oil as well but I'm not sure where that is other than driven by the HPFP. I took additional pictures but those were useless, it's a bit cramped in this area.
In the past ten months I've had the turbo coolant inlet pipe leak repaired and then the DEF heater failed, which means replacing the entire pump of course. The wastegate solenoid air compressor noise started some time ago as well at shutdown but I haven't been concerned about that (it doesn't seem to cause an issue). 96,000 miles.

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 06 f250 that has a coolant leak in the front of the engine. It's was leaking about a month ago replaced the water pump it stopped. Then about 2 weeks later it started back up again. It only happens when the engine is cold. But once it warms up it starts leaking again. I am confused as all get out on this.

I have a 2000 f350. Lost power whole driving and won't start back up. I have checked all my fuses and relays several times. Have no power to the fuel pump. Tried running a hot wire straight to the pump and still nothing.checked my emergency cur off switch and there is no power there. Also my WTS light isn't coming on now. Tried checking the heater bowl and no power there.

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.
