Ford 7.3L Power Stroke (1999-2003) :: 2002 - Turbo Noise From 5 To 15 PSI Intermittently?
Aug 29, 2016
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'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 have a 2002 f350 dually with a 7.3 and 197k. At 186k it died while driving and I had it towed home. As soon as the tow truck dropped it the truck fired right up like nothing was wrong. Then it died again 2 days later. I replaced the cps, but the fix was replacing the icp and pigtail. Now it is doing the same thing again. It died on my wife while driving yesterday, i had it towed to the dealership I work at and it started and ran for about 2 hours with no issues. I hooked up the factory IDS and had a diesel tech look at it with me. The oil pressure, injector circuit and injectors, and IPR all look good. The batteries were a little weak so i replaced both of them. I drove it home yesterday, about 10 miles, and drove it around town today. Then i tried to jump start my 96 bronco and after about 10 minutes of running it sort of hick uped then 5 minutes later it died and would not start. I let it set for 30 minutes and it started and died after about a minute.

2002 F350 7.3 intermittently wont start after I've shut it off, it runs fine but sometimes won't start when it's (warm)? Wait hour or more and it starts right up.
Is there something I can look for before I bring it to a mechanic?
Just to clarify I am a gal with little wrenching skills but I can look at videos and follow directions if it's not too involved.

I have this strange noise coming from the front end. It happens at the most random times. It is at the end of the video. It's kinda hard to hear over the engine noise.

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...

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.

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

I have an 02 F350 7.3 6 speed with only 86,000 miles on it ... Ive owned the truck about a year and a half now and ever since i can remember the transmission has had this growling/Groaning/Vibration sounding noise when ever Im in 1st or 2nd slow rolling with barely any throttle. Itll make the noise going slow and as soon as i let out on the clutch and start moving, but once i give it a little more throttle and start moving at a more proper speed for the gear, the noise fades away ... Id assume its just the transmission making noise due to the low speed and RPM when slow rolling or just starting from a stop.

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

Having an issue with my 05 f350. Seems when I chomp on the the throttle I get tons of boost 30 lbs plus with no power. Seems most prevalent when starting on a hill , or hard on the throttle off the line . Also getting turbo "bark " when backing off throttle. It's less prevalent when feathering the throttle and usually more noticeable 1/2 throttle or more. I'm thinking could be the Vgt actuator or clogged/ dirty ebp sensor?

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'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 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.

I just did an engine swap and have an odd noise that I was curious on where to start. It sounds like a buzz test on an injector at 2,250 rpm and gets louder as rpms increase but starts out very faint and get louder. Makes noise converter unlocked and locked in gear under load and free rev no load.
-2002 F550
-Fuel pressure is 60+ psi all the time
-Regulated return fuel system
-New injectors all AD
-Stock tune
-38R turbo
-New flexplate
-injector hold down tight
-new degas res
-new water pump.....

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.

I just changed u-joints and the carrier bearing on the rear driveshaft. I now have a "howl" somewhere back there. The noise starts around 30mph and goes away around 40mph. There no vibration associated with it. The sound goes away after driving for 15-20 minutes.
I double check all my marks on the driveshaft to make sure I put it in the way it came out. I put it up on jack stands and ran it up to speed but couldn't replicate the sound that way.
The truck is a 2002 F350 7.3ltr DRW.....

I have a Stock 02 f350 7.3 with 66,000 miles ... I'm sure this has been covered plenty if times, but I notice more so on cold days (-20 to 30). My truck after starting and even letting it warm up for a period of time makes a hissing sound from the passenger side of the cab near the dash/glove box area, Like I said I've only really noticed it on cold days ... It usually occurs between 1200 and 1800 rpm and it's a very touchy noise, for example I only really hear it when I'm cruising at a consistent speed, if I get on the gas a little it goes away till I bring it back to consistent throttle cruising then it comes back, same goes for when I let off the gas it goes away until I give it a steady consistent throttle again ....

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 ?
