Ford 7.3L Power Stroke (1999-2003) :: Oil In Exhaust System
Sep 14, 2015
I just installed a new MBRP 5'' exhaust system in my 7.3. I have only put a few miles on the truck since it was installed and I now have a black thick oily residue in the tailpipe. The exhaust system had some sort of oil in it when it was shipped. I remember getting it on my hands when installing it. I think the oil in my tailpipe is just the oil burning out of the exhaust system which mixes with soot that turns it black. When I installed the new up-pipe, the exhaust side of the turbo was dry. Like I said, I haven't ran the truck many miles with the new system yet. A few friends of mine have looked at the exhaust and they think I have a bad turbo seal. I didn't have any oil in the exhaust with the old system. It was sry. My truck has 135,000 miles on the original turbo. I hope my turbo seals aren't bad.

Usually in the OBS 7.3 but a buddy of mine with a 2003 6.0 is having some issues. When he romps on the pedal but when he does so he claims he can smell exhaust in the ventilation system. I rode with him and smelt it as well. So I inspected all exhaust clamps and piping as best I could and did not notice any soot or leaks while running. I don't know if it pertains to it or not but his heater only works on defrost.

Recently I came across a guy parting out his F-250 with a 7.3 powerstroke. Said it had a blown engine, and didn't know what was wrong, but oil was coming out of the exhaust.
My question here is why that's happening. I don't have any experience with the powerstrokes, so I'd like to know what the culprit is before I even consider buying it.

I own a e1999 Ford F350 7.3 4x4 with a Garrett GTP38R turbo. I have been having issues with very little power and pulled an CEL of P0221. I know it's for the APS and have been trying to trouble shoot it as a new APS has not fixed the problem. However, while working on that I just noticed an oil leak appear. I tracked it down and can visibly see it leaking out the top of the passenger side exhaust manifold in two places. It is seeping out the top. Is oil supposed to even be running through here like that?
I recently replaced my up pipes with the newer style bellowed ones. While I had the turbo off I replaced all the o-rings top and bottom and did the EBPV delete on the pedestal. I have been having very little power and cannot the truck over 5-10 MPH and stays at low RPM's so I originally thought it was the leaky up pipes. Those were fixed along with fuel pressure checks which came back good. I then pulled the P0221 code finally. While I had the turbo off I inspected it and it did spin freely and had no side to side play in it.
What was unusual to me was there was a small pooling of oil in the turbo when I took it off. I know the CCV goes through here so some oil is normal. Also, when I was diagnosing the up pipe leak I could see a small amount of oil spraying out the blown donut gasket along with the exhaust gases. I don't think that is normal.
Is there an internal seal in the turbo that can go bad causing oil to spill into my exhaust and possibly leak at the exhaust manifold? Or do I have an internal oil leak from somewhere else?

New up pipe and manifold gasket time!
Massive exhaust leak.. Likely the reason for my 5psi boost.
Wish I had the funds for headers but on the up side, no broken bolts!

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

I'm having an issue with massive oil consumption and no oil leaks on the ground! No clue where the oils going but I burned more than 2 gallons today in a few hours of driving exhaust smells awful but the truck is running fine.

I've been mulling over the idea of doing a muffler job on my 2002 f350 7.3 cc short bed. I do tow on and off for work and dual material for work. I am thinking of upgrading the exhaust because I noticed a couple small leaks in the muffler and I'd like to lower the egt's for the truck so it breath a bit smoother. I'm not a fan of the really high pitched sounds I've heard on some I want it deep and heavy sounding. The turbo is fine for now but eventually I'll need to know what to upgrade to once it starts to wear out. I don't plan on doing dumb chips or tunes because it's not a toy truck but a work and daily driver.

Just bought a 03, the seller showed me a exhaust leak. I found a bolt broken off, flush with the head. Looked at the passenger side when I got home, that side leaks too, and found one broken off bolt there too. Question, are these easy to do? As in, I have extracted broken bolts before, but they where on my V10 and I could just weld nuts to them and they came right out.

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 have a non ebpv pedestal I was going to clean my sensor on the front because my mileage has went down a bit. My question is is this even worth doing since the valve is not there anymore I have got mixed answers trying to look it up some say it still affects the mileage some say it won't. I cleaned it once about 10 years ago. I have an AE also how do I test it and what should it read if I do need to clean it or replace it?

So I received my International bellowed up pipes from Riffraff and I figure I will start soaking all of the bolts with some aerokroil before I get started on monday and I see the very last bolt head near the up pipe is gone. The bolt is there but the head is gone and you can definitely see soot buildup everywhere near it. I don't know if I should order a new manifold for the passenger side and new bolts, order a driver and passenger side manifold and new bolts, or just order one set of new bolts and try to get take the passenger side manifold off and replace the one broken bolt.

I managed to get the drivers side exhaust manifold and all of its bolts off no problem. On the passenger side I had 1 bolt head that was already broken and I have only 1 other that is still holding on for dear life. I've been soaking it in aerokroil for awhile now and no luck. I tried some PB blaster today because I am willing to try anything. I also tried heating up the bolt with a torch and some map gas but not sure if I am heating it up enough or not. Anyways, everything else has been going great, got the uppipes off and the valley, turbo and pedestal all cleaned up good. Just need to get the last whole bolt and broken bolt out so I can install the new manifolds. What I should try to remove the last 2 bolts. How hot should I get the bolt when trying to remove it? Or should I be heating the engine block?

Well i had an exhaust leak on this F250 and so I started torquing the bolts on the manifold to the head. (45 ft.lbs) A couple were very loose so I was thinking "Great, this may fix my problem!"
My first mistake was probably the Harbor Freight Tools torque wrench.
I am on the driver side, second from the rear and then bang! I see a gaping hole where the bolt used to be. Bolt on the floor. I cant see up in the hole to the head, I think it broke flush with the head.

So changing the oil in my truck the other day, I noticed the exhaust clamp at the union between my down pipe and first section of my exhaust has been rubbing the trans cooler line and there's a Nick in the granny pan. Lookin at the rubber grommet on the hanger, its stretched tight and looks like the exhaust has shifted over. What could have done this or possible fixes?right by now it's got a gob of high temp silicone acting as a stand off. Don't wanna put the new line in until I have the situation remedied.

I was driving my bosses f550 with a 7.3, and while towing a loaded 40' flatbed of hay, it started bloing white smoke and lost all power and had almost no pedal feel. It wouldnt even go past 2500 RPM. Then, all of a sudden, it started billowing black, and BOOM backfired and shot flames out the exhaust. Then, I pulled over at a parts store and replaced the fuel filter, which worked for a while, but then it started blowing white smoke again. Once I limped it home and unhooked it, I took it out and let her rev a bit and it seemed to stop blowing smoke, but it still has less than the normal power it used to have. It has 226000 miles and is completely stock.

So, I just got my turbo back from my pal Ruben at SoCal Porting (does good work fast and inexpensive) and, I have a question about the exhaust housing with the EBPV.
Is there a gasket that goes between the turbine housing and the adapter that the down pipe mounts to? And, if so, what is the part number for it? If it's steel to steel cool. If not, I'd prefer to put the OEM gasket in there versus permatex or something similar.

2001 SD F-250 SuperCrew 4WD, 7.3L (completely stock), 114K miles, automatic
We took Dad's SD for a 600-mile trip yesterday and today. The oil had 2000 miles on it, and we checked it before we left. The oil level was half-way down the hatch-mark, so we had added a little over a quart of oil to top it off, and I think that we may have added a little too much. Last night, when we got to the hotel and got out of the truck while it idled, a lot of white smoke that smelled like burning oil (like when you spill oil on an exhaust manifold) was fogging out of the exhaust.
It did this for a minute or two, then cleared up. All day today, on the way home (300 miles), about every time that I let off of the throttle either going down the interstate or stopping at a red light or stop sign, white smoke would pour out of the exhaust briefly, then stop when accelerating or in the throttle going down the road. What is causing this? Would too much oil (a little over a quart too full) make it smoke like this? The truck runs strong, starts and idles good, and no 'check engine' lights came on the dash.

I have a 2003 Superduty with 193k miles that is bone stock. I sold the truck to a friend and when he decided to not pay the remaining balance on the truck, I took back ownership. The truck was having heating issues and it set at a mechanic shop for nearly 2 years waiting for a diagnosis on the heating issue. Fast forward to the present and I now have the truck at my home. Heating issue was the radiator but this is no longer a concern. When I went to pick up the truck from the mechanic, the truck started fine. Every other day for the last 4-5 weeks I would start the truck with no problems.
I get the truck tagged and start driving it on a daily basis. I've put several hundred miles on it but the more I drive it, the less it wants to start. Now it's to a point where it only cranks but won't start. I can take a gas rag and hold it in the intake and eventually it will start. Once it's running, it runs great and has no issues starting. But once it sets for 3-4 hours, it won't start without some sort of assistance.
While trying to find the issue, I've found and repaired 2 fuel leaks and in the process I replaced fuel filter, air filter, replaced glow plug relay, replaced batteries, replaced CPS. Fuel pump is working fine. I've tried the ICP test and doesn't make a difference.
The glow plug light or WTS light works so don't think its the GP. The CES light was on. Had it scanned and it was the air bag sensor so no support from the CES.
While I was working on it yesterday and after cranking on it for 5-10 minutes, it would act like it was going to start and black smoke would be coming out from the exhaust. I let it set to cool the starter it fired up like it had no issues.

I have a 2001 F-350 w/7.3. There was excessive smoke coming from the exhaust. So the first thing I did was to pull the glow plugs to see what they looked like. and while having them out I cranked the engine over. Upon doing so I noticed 1 cylinder putting fuel out of the hole. Meaning it was like you could put your hand about 6 inches above the hole and your hand would be wet from fuel. None of the other cylinders was like that. So what I did was pull the injector from the cylinder next to it and put it in to see if it was the injector failing. But it was still doing the same thing. What would cause this??

I only hear it in gear under load so I can't stick my head under the hood to pin point it. I dont see any black streaks and I replaced the EGR tube. Is it commonly just the gasket or do the manifolds crack? If they crack where?
