Ford 7.3L Power Stroke (1999-2003) :: Swoosh Noise When Shifting Is Normal / Chirping When Coasting
I just installed the Donaldson B085011 filter last night. I understand the swoosh noise when shifting is normal. But, I noticed a chirpping when coasting. I first suspected suspension parts maybe but after reading on here could it be surge? I've seen some videos of what surge sounds like and it does sound like that but most people say it only happens under load and I'm hearing it just coasting down my farm market road to a stop sign without hauling anything. I'm researching billet compressor wheels now. Am I on the right trail to resolve this?

So I have a 2002 7.3 Excursion and I think it is low on power. ICP is falling on its face when on a 60 or 80 HP tune. I have some boost leaks at the plenums and will work on that but that shouldn't cause my ICP to tank at full throttle. Following are some numbers I pulled with WOT runs up a 6% grade.
16PSI BOOST
EXHAUST PRESSURE 40
ICP 1900
80%IPRDC
this is with the 60 or 80HP tune on my DP-tuner. If I ease into the throttle I get
2700 ICP with
45%IPRDC
but if I stomp on the throttle it stumbles and ICP tanks.
Running the stock tune I can maintain
2700ICP at
40-45%IPRDC
Is this my HPOP being weak, or worn out injectors, to much of a tune or a combo of all three?
Ford 7.3L Power Stroke (1999-2003) :: Won't Start - Bad Injectors - Coolant In The Oil?
So we begin w/ another saga for the 7.3l Excursion......
A few months ago it started running like crap, real crap and blowing white smoke like crazy. Well I knew this from a previous episode and I had a bad or multiple bad injectors. I tried to trouble shoot which one it was and maybe just replace the one or two....but no it was worse than that. So Life was really busy it kinda got shoved aside until now.
I pulled all the injectors and had them rebuilt locally ..nice. They ended up being with mech for a couple of weeks because he went out of town...no problem. Well this entire time my rig was untouched and when I got them back #7 was full of water.....great, bad injector cup. #7 was the only one, the rest were dry. So I drained the radiator and the oil and left it overnight to completely drain and installed the new injector cup in #7. Next day I refilled via both heads because the valve covers were off, 4 gallons of oil and a new oil filter. Cleared the cylinders via the glow plugs and commenced to trying to get her started. Nada......just cranks, killed the batteries, recharged over night and left the box on them and still nada....but the oil was still very milky at this point.
So tonight I pulled all the injectors back out and drained the oil again, still a lot of water. This time I sucked out the HPOP reservoir and got a more milky water/oil out and I'm leaving everything open all night.
In the am I plan to check my overflow water level in the hopes it remains at the same level...if so I will reinstall all 8 injectors and refill the motor w/ 4 gallons of fresh oil and try again.
Oh, while I was attempting get her started I put my buddies Snapon scan tool on it and I got the p1271-p1278 codes w/ the buzz test. (low side to high side open circuit between idm and injector) So I found the pin test with everything connected at the idm pigtail and everything tested good. So I'm back to my not so fresh oil anymore is the culprit to it not starting.
Am I missing something here?
Also....another fun filled fact is that I seem to have a fuel leak somewhere at the rear passenger side. Every time my fuel bowl fills up, if I shut the key off it will drain down. Sometimes I can see fuel dripping quite vigorously onto my starter but I can not see where it is coming from. I have while it was dripping ran my hand along the head and the fuel lines and can not find where it is coming from. Any thoughts as to where in the hell this fuel could be leaking from?
Ford 7.3L Power Stroke (1999-2003) :: Injectors Barely Spitting Oil
This is a 1999 with 200k on it. It has a really bad hpop so valley is full of oil. Haven't removed the HPOP to inspect the non serviceable plug or the hpop gasket. doing that this week. This truck I just bought and it has aftermarket injectors so dont know the miles in injectors. once the oil leak is resolved I can then give the injectors the once over to make sure theyre okay. Question is how much of a stream of oil should I expect to see as the engine runs?

So I got all 8 injectors upgraded and excited when I get them back I put them all in in kind of a rush. And in that rush I left the cylinders full of excess oil. So obviously when I tried to start it hydro locked. Angry at myself. I kept trying to crank hoping it would fire and just shoot that oil out. Nope, so I went back to taking all the glow plugs out and firing it all back out. Put it all back together then tried to fire her up. Took a minute but she started and I let it run for a while. Hit the gas a few times and then it died. Couldn't get it started again. It would just crank, I checked the icp and ipr and the icp did not build above 35 psi and the ipr was at 98.04% so I just figured the o rings blew out when it hydro locked.
So I took it all back apart put new o rings on, took my time and put it back together right double checking everything. Got it all back together and went to start it, it would just crank around 160-170 rpms, battery voltage at 10.6 icp built up to 140 but now it won't build past 40. Ipr still goes to 98.04. The engine ran just fine prior to injector change, I put a new upgraded hpop prior to injector change, new ipr, icp, cps. Everything checks out, but it will not build oil pressure while crank I've killed a set of batteries then went all out and spent 350 at napa for some optima red tops. I did notice the cylinder 7 injector is the AE injector. It suppose to be in cylinder 8, idk if that's affect the oil pressure building up?
But as far as I know, I'm not building oil pressure. So idk if the hydro lock could have ruined something to keep it from building oil pressure?

What causes oil coming out of the oil spouts on the injectors? I pulled my VC to re torque my injectors down and I noticed 2 of mine are now leaking oil out the spouts(when warming the engine). Note I did not say the base of the injector.

I changed my injectors and glow plugs on passenger side. I tried to start the engine and it wont crank (turn over). I tried to turn over by hand by turning alternator bolt counter clockwise, turns a little bit and then get very difficult. Is this hydro lock? I stuck a suction tube down injector holes and made it to the piston not much oil came out, I think the truck was a little low on oil before I started the project. The starter wont turn the engine over. I even turned the engine over by hand many times before I put glow plugs in to evacuate the cylinders. I don't know what to do?

Ran torque for the first time on my f250, I used it for diagnostics to see if i can find out whats causing the surging. At a red light sitting idle it shows my icp at 705psi seems high to me? I'm running a dp tuner, it was set at stock for this run. It starts surging between 35-50mph and when coasting at about 60mph, surges during light throttle or maintaining throttle at low speeds. If i go about 70mph and up it runs like a champ. Ive changed the tps(entire pedal assembly), uvcg connectors, icp and pigtail. No CEL comes on, torque shows ipr is good, working on hpop pid. I just bought the truck last month and haven't been able to enjoy it much since it started doing this. ...
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: New HPOP And Injectors - Long Cranking About 15 - 30 Seconds
I recently did the following work:
New Injectors
New T500 Hpop
New IPR
New ICP Sensor
New UVCH/Glowplugs
New starter
Been cranking about 15-30 seconds each time about a dozen times now. I've pulled the icp and the hp crossover and have oil flowing at each.
ICP builds to about 240 psi and at a 98% duty cycle....so I assume there's still some air in the system. I"m not getting any sense that the engine is trying to hit. Do i just keep cranking?

I just replaced all 8 injectors in my 01 F550 with remans from FFD. I have noticed a constant knock at idle but truck runs great. Blowby has no pressure behind it, truck does not smoke. Does this sound like a problem unrelated to an injector?
It did not make this noise before replacing the injectors

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 Not Turning Over After Injectors Replacement
So I replaced all the rings on my injectors . After putting them back in turned the engine over 5-7 times by hand with the glow plugs out. Then I turned it over with them out as well with the valve covers off. After than I installed everything back in. Now is my problem. I've turned it over 5 times and no luck. Not even on turn over. The oil light keeps coming on?? The indicator doesn't move up at all. It will go up and come down ? Is something wrong with the hpop? Should I keep cranking? Gotta to charge the batteries now..

Ford 7.3L Power Stroke (1999-2003) :: Front Wheel Making Screeching Noise - Lost All Steering?
Ok, so I leave the fire station this morning headed home and my steering felt weird. About 1/2 mile from home I hit a bump and my drivers side front wheel started making a screeching noise. I stopped and looked out the window and it appeared fine. I limped home and as I pull in the driveway, I lost all my steering. I look under the truck and this is what I found.
Not sure what to do. This is my daily driver and neither of my 2 mechanic friends will answer their phones.
