Ford 7.3L Power Stroke (1999-2003) :: Smoking And Leaking Oil
Aug 17, 2017
I have my 2002 Ford F450 7.3 diesel in the shop right now. Early story is it is leaking in the turbo or there is a problem with the turbo. Last summer I took the truck cross country and 500 miles from home I was gunning it to get on the highway and it started acting up (poor excelleration). And it started smoking and leaking oil. I crippled it home at lower speeds. Now that it's in the shop they told me about the turbo but have to keep it till tomorrow for a closer look. My question is what else should I consider since they have it in. I mean should they replace the turbo while their at it or any other parts that make sense since they are already into it?

I have a 02 power stroke 7.3, driving down the road the other day is started smoking a grayish white smoke pretty good. i let off the throttle and it had a real loud knock along with the smoke. oil pressure was good. i stuck it in neutral and revved it up kept smoking but the knock would go away at higher rpm. then all at once it would stop and run fine. then today it started doing it and wont stop now at all.

Just picked up a 99 F250 7.3 Stroker, it had sat for two years in a warehouse, the truck had just had reman injectors put in right before it was parked. We fired it up, and it was missing, and smoking a lot (light blue, almost white) I checked the oil filler cap, and no water on it, after it ran for a while, it stopped. Shut it down, went and got my trailer ready to load the truck, fired it up, and no smoke to speak of, by the time I got it to my trailer, still no smoke.
I revved it against the governor a few times, hoping to clear the miss (figured may have been trash, or a sticky injector from sitting so long) It is turned up pretty good, as it came with a Superchip Super Tuner. It seems to hit on all eight above 2500 RPM or so. Brought it home, and took it out on the road, it seems to only miss under 2500 RPM or so. I took of from a dead stop, then got on it hard at about 15 to 20 MPH, it took of nice, then all of a sudden, the tach started climbing like the trans was slipping, looked in the mirror, and the tires were smoking, guess they broke loose when the boost came in!
I let it idle and warm up for a good half hour and noticed a lot of pure white smoke coming from the exhaust, went back to it and it was steam, I took the oil filler cap off, and there was a lot of steam coming out of there, pulled the dipstick, more steam, I then noticed the degas bottle was low, I topped it off, and got in the truck, and revved it a few times, then held it at 2500 RPM for about a minute, It started blowing water out from under the degas bottle cap. I called the guy I got it from, and he did NOT put new injector sleeves in when he did the injectors, I don't see any oil in the water, but there is water getting on the oil filler cap now! Does it sound like a head gasket, or an injector sleeve?

Picked up my 5th wheel this afternoon from being raised 3". Dropped over the 10 percent grade down the hill to normal driving. Had the trailer brake controller to boost #2 (Prodigy controller). Had to brake pretty continuously, (tried to stay off it a bit, but is is about 10 grade for about 3/4 mile. Put the auto trans in D2 to get brakes come to the red light at the bottom. Noticed a puff of smoke at the front. Driver side, didn't notice passenger side.
New pads and new slotted rotors new maybe 1,500 miles ago. Not liking that action, but need thoughts. Want to put a thousand or 2 miles towing this summer and accompanying mountainous terrain and back.

Looking for a write-up on replacing the seals on the hose that leaks at the power steering pump? I replace them once but may of over tightened them. I pour in atf and see it dripping on drivers side of power steering pump. Can I just use regular o rings?

I did the extended seal kit and non-serviceable plug on my HPOP and now the CEL is on. It is throwing the below codes. The truck in all reality runs fine and even a little better on a cold start than before resealing, just the CEL is on.

P1209
P1282

I cleaned the IPR when it was out when I put new seals on it but could it go bad by just taking it apart? The ICP and IPR are definitely plugged in. The truck is all stock, no chips.

I let a small leak that I thought was engine oil go too long it appears before checking the transmission which had still been working ok. I added a whole quart of Lucas and then another quart of Mercon so the level was pretty low. What to do next as I am about to leave Alaska and go back down the highway. Is my ZF trashed now? Still seems to work fine. Or is there a seal somewhere that I can change?

So just a couple hundred miles ago I changed the oil and oil filter in my 99 7.3 ... It wasn't till today I noticed an oil/coolant leak ... It is on the driver side of the engine by the oil cooler ... "It isn't the oil cooler leaking already checked"... It seems to be behind the water pump to the driver side of the hpop... Where the thermostat is it is like right behind that but I can't think of what it is .... Its not the oil pump leaking ... It is leaking down and being blown back across my oil pan and oil filter... That is the oil cooler it has residue but its not the problem

Initially 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?

So my understanding is that if your turbo is leaking oil, you either need to rebuild it or get a new turbo cause the one you have is shot.
I have some oil leaking, but it's not a ton. One one of my buddies was telling me that it's possible that the amount that is leaking is normal due to the PCV (Pressure Control Valve) system, or something like that. Here are a few shots of the turbo, as well as the boots that are leading up to the turbo.

I have a 2000 f250 super duty extended cab with the 7.3 diesel and auto tranny which the tranny was rebuilt by Samco about 7 years ago and I have 337,000 miles on engine I had a oil leak from I believe my oil cooler which I fixed, but I am still losing oil, about a gallon or more every other day and in that time frame I am only driving maybe 30 miles. I have no drips, and I seriously don't believe it's burning because the truck is not smoking even when you rev the motor up. the bottom of the rear of motor is coated with oil plus as is part of tranny and some front of motor bottom. What to look for?

I have a 99.5 with 400,000. on the engine. It has been a great truck but it is time for the some TLC. I have a little leak on the radiator and the water pump and would like to replace it. I am just looking for stock.
I have a 13 yr old that grew up sitting on my lap as we drove the dirt roads around the house and on the ranch. He has been driving this truck by himself (on the ranch) as soon as he was able to reach the pedals, around 8 or 9. His happiest day will be when he gets his drivers license and can drive the truck to school. So I have a lot of work ahead of me on this truck.

I purchased the truck over a year ago and never had a problem with the transmission. The only issue was a leaking transmission pan gasket so I changed it put the same fluid that came out back in it since it looked brand new and didnt smell burnt or anything. So fast forward time and my girlfriend was driving the truck over the winter and lost control of the truck and spun it around and hit the front end of the truck into a rock wall.I have a weston bar on the front end that took the majority of the hit.
Shortly after the transmission would start to run warmer than normal. It would be 20 degrees outside and my transmission temp sensor would be reading around 140. Now that the weather is getting warmer the transmission is heating up a lot more. I took it to a guy to have him look at it and thought maybe the cooler was clogged or something like that and possibly put a larger cooler on it. He called me up a few days later and said their was a larger cooler already on it but it was not hooked up. It is a black one mounted on the front of the radiator. He said he cut the lines off of the old one and there was a slight bend in the one line so he cut a little higher than that line and then hooked up the cooler.
He told me he blew in the lines and there was no restrictions in it, i guess no pressure when we blue on the lines. I drove it home and the temp went higher than ever before up to 220. The cooler on the front was ice cold and trans pan was hot.I am starting to think maybe the bypass is bad and the fluid isn't getting to the cooler. The fluid is still pink and does not smell burnt so I want to fix the problem before any issues arise. The truck has 137000 miles on it. I have attached pictures of the cooler that he said was already there but not hooked up.

I have a 2003 Excursion with a 7.3 and 240,000 miles. I have oil leaking around the transmission and the local diesel shop found the pedestal leaking. I installed a new pedestal from Rotomaster Part # A1382205N. It came with new O-rings and turbo bolts. I ran the truck and it began leaking again. Thinking I had pinched an O-ring I pulled it apart again but found nothing. I cleaned and inspected everything and reinstalled. Its still leaking. I used a straight edge to ensure the sealing surfaces were straight.

about to fix my leaking HPOP and step up to an Adrenaline. Looking at replacing the discharge fittings when I do and have a quick question. Dieselsite instructions say the oring seals it and to only run it down to where the fitting body touches the pump. Diesel orings instructions say the 680 locktite does the sealing and to torque to 25 ft/lbs.

My transmission on my 2002 7.3 4x4 is pouring fluid from somewhere above the rear of the pan. I thought it was the pan at first. I pulled it off and replaced the filter. After adding fluid while it was running for 4 or 5 minutes it started pouring again. It's not the pan. It's coming from above the pan somewhere. It won't leak unless it's running. Is there a place it can leak on top??
