Ford 7.3L Power Stroke (1999-2003) :: Oil Leaking From Turbo Area?
Jun 29, 2016
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.

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?

Well I am at a loss now. Rebuilt the turbo with a new wheel and kit from Riffraff. I still have no power, no boost and no codes. The new wheel whistles. I can hear it. It sounds way better than the old one. But still no power. I really don't know what to do now.

As I was getting ready to leave town with the tractor loaded up, I was accelerating with the turbo spooling up when I heard a bit of a pop and lost power (engine still running and all, just very low power like you get when the turbo fails). I wasn't far from the shop so I came back and started getting a lot of white smoke out of the exhaust, it doesn't smell like diesel, probably more like oil. Definitely smoke, not coolant. I pulled it around back and shut it down to go grab AE and scan it and it shows a P0475, starting it back up has light smoke at idle and it idles fine but as soon as you give it any throttle it starts smoking pretty badly.
Researching it looks like the most likely cause for this is the EBPV itself but before tearing it down that far. This is the only code it's showing.
Truck has 272k on it, turbo was rebuilt a couple of years ago but we didn't do anything with the pedestal at that time. I guess in retrospect, I probably should have done the EBPV delete and the resistor fix then but I didn't think about it at the time.
On another note, my AE is not showing any of the system test for some reason, the drop down is blank. I have version 7.0.1, so it's an old version but I'm working on an old truck, so... What that might be? I've got the truck pulled into the shop now to let it cool down. I'll probably let it sit overnight and take the turbo and EBPV out tomorrow unless someone has a better suggestion...

While my turbo is out I decided to delete the EBPV. I removed the butterfly and rod, & pounded in some 3/4 inch freeze plugs. Are there any mods that need to be done to the pedestal, or can I just leave it the EBPV plunger unhooked? It's not leaking, but will it leak if left unhooked? Or do I have to gut it and tig weld the oil gallery's

Would there be much oil in the down pipe if the oil deal was leaking on the turbo? I broke it loose to look at it and not much there, one small area that looked like it has had on it..

Dumb question but how do I remove the air filter intake from the turbo Its a little oily there from a fuel or oil leak but I dont see a clamp holding it on the turbo?
Also what is the e clip? Is it the little thing holding the wastegate rod on the exhaust turbine? Can I just pull the rod up off the clip?

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.

I'm getting ready to change the glow plugs in my dad's e99, 196k on the clock. When I pulled the air intake tubes I found some oil in the turbo:
The inlet tube also had a bunch of gunk in it too:
Does this look like it is caused by the PCVor is it a bigger issue?

I have an 02 crew cab SB 7.3L. The best way to I know to describe it is a sorta like a metal ringing noise. It just started this afternoon while pulling a 9k camper. It only does it under load. Boost stays the same and it happens in all ranges from 5psi to 15psi. It is intermittent. It sounds like it it coming from the turbo. I pulled off the boot and could not feel any play on the intake wheel.
After unhooking trailer and taking for a test drive I can not get it to do it again? The turbo was rebuilt about 4 years ago with a wicked wheel but has only seen about 18k miles since the rebuild. A quick look at the boots appear good but didn't get to take them off before going to work. I will try to post video.

I have done some searching on this, seen a video on YouTube but haven't read anything that is firm on what it is. We pulled our 5er for the first time last weekend and the chatter was pretty pronounced in the Arbuckles here in OK. I was running around 65 mph when I hit the largest hill and as I was climbing my speed naturally dropped, boost was around 17 - 18 psi when the chatter started.
Is it something to be really concerned about? Is there anything to be done to prevent it? I'm pretty much still stock, only deletes have been airbox to 6637, and I deleted the heater by turbo for the boost gauge. Other than that everything on truck is still stock.

For a while now, I have been hearing a very high pitch whistle noise from the turbo/exhaust area. Everybody told me it was an exhaust leak, but I never could pin point the leak. While I was under the truck last weekend I found the flex joint on the passenger side up pipe was broken a leaking.
I ordered a Dorman replacement pipe that comes with a new gasket and hardware.
I will be the first to admit, I am not a fan of Dorman parts... BUT, this pipe is really nice. It looks identical to the pipe being sold on Dieselsite.com, it doesn't have the scoop inside to direct exhaust gas to the EGR cooler and it comes with all the mounting hardware.

Once I got the turbo down pipe out of the way and soaked the bolts with penetrating oil, I had the broken up pipe off in 30 minutes.

I am experiencing leaking cooler lines at the turbo. I thought it was only the line coming from the side of the turbo, but it looks like it could be the one going into the top. Can I safely remove the line from the front of the engine without interfering with the other metal lines directly in front of it. See the pic. This is the front of the engine under the turbo.
Also, the fitting in the pictures is not leaking. Can I replace the metal line without replacing the threaded connector going into the engine or does it have to be replaced with the line? I already have parts BC3Z-6A968-C and BC3Z-9U469-A for the line coming out of the side. What is the part #s for the other line pictured?

I have a 01 7.3 F-350, 120000. I rarely get down hard on the go pedal but a while back I did and heard at pressure whistle just before it would shift. I thought a bad turbo hose so I replaced them all. 'While working on the hose mounts I cleaned up the castings for a better seal'. The hose replacement seemed to get the running but the whistle is still there. I am thinking a leak on the manifolds for the Y-Pipe connection OR does the turbo have a release valve that can make a whistle sound?

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.
Pic of the compressor housing with a little port work....

Are we supposed to put anti sieze on the turbo to pedestal bolts. They were really hard to break loose when I pulled it Cheater bar tight. 18 ft. lbs sound right ?

I've got a 2002 Excursion which has been giving me a little trouble lately. I've got a DP tuner, 4" exhaust, afe stage 2, and gauges (boost, trans temp, EGT). I've been running these for about a year now without any truck problems until recently
So I noticed over the past couple weeks it has gradually been taking longer for the engine to start. Started off by just having to turn the engine over a few more times. Now it has turned into having to turning over the engine for a few seconds, then turning it to off, then trying again. It always starts on the second attempt to start my truck and sometimes really hard where it blows out a little black smoke.
Not sure if this is a correlation to the problem above or not, but I've also been losing boost pressure, and I'm not sure when this started since I haven't been on the highway for a while. I noticed this because this weekend I drove on the highway and saw that I was blowing some black smoke every time I accelerated which has never been the case.
So I check my boost gauge and see that I'm sitting at like 3-5psi when I used to be at around 10psi+. I also noticed when I accelerated the boost pressure would increase like normal but then quickly drop once I stopped accelerating which is unlike anything I've seen before in my truck. I don't seem to notice a huge difference power or throttle response, but then again 95% of the time I'm driving under 40 mph to get to work. So this problem could have started the same time as the starting problem, but I can't say definitively.
What this problem could be, what to check or test?

I'm on the road and I pulled over for a pit stop so I don't have time for a search right now, but I noticed under heavy acceleration a turbo whine so high pitched it almost sounds like metal on metal. Is this normal and I just noticed it, a leak somewhere, or maybe indication of something worse? The truck seems to be running ok otherwise. It's an '02 w/7.3 and 220k miles.

I put a ts6 on my 2001 7.3. I love it shift points are better and truck has a lot more power. But I've noticed when I shift truck shifts into 3 (especially going uphill) I get a really weird turbo sound where it acts like its gasping for air (I have 6637 air filter) and then it shifts kinda rough into third. If I put chip on stock setting it doesn't do either of the things I described. Do I have loose turbo boots somewhere or possible bad turbo bearings?

Been a while... Problem today while towing... I was in some hilly areas but nothing too .. I was pulling an unloaded trailer and experienced a significant loss of power and overheating. Engine started getting hot (almost to red) and then the transmission came up in temp. Made it to a rest area and all cooled down within 2 to 5 mins... but the strange thing about the power uphill is that it is happening at slow speeds as well... boost seems normal. Recently did the injector cups, so the thermostat is new (motorcraft), coolant is new, and put new o-rings on injectors.

ive noticed my boost has been going down lately. At first I thought it was a boost leak so I replaced all the intercooler boots and both sides of the intercooler pipes. That diddnt change anything at all. I recently got new injectors (200/30%) and a hydra tune for them and it was quick the first few days i was running with that setup, my boost has been dropping and currently at WOT I can't even get to 10lbs of boost and it is noticeable driving, it's slower than it was stock. There was no play in the shaft of my turbo and the turbo in there is only 2 years old. Could the turbo be bad already? Or is there anything else I can check before buying a new one. I have an upgraded hpop and the 6637 intake.
