2000 f450, truck has been running great and then all of a sudden starts running really rough. I check the oil and its dry! it was 9 quarts low! i checked the oil 2 weeks prior as i often do. i change the oil every 4500 miles and now this. i had driver side injectors done about 5 months ago. I take it to my mechanic and he said he thinks it has low compression on 2 cylinders but didn't do a compression check( not sure how he knows). He told me to run it until it pukes , keep putting oil in it with lucas oil additive. Then i will have to have the engine rebuilt. The truck only has 175000 miles! i thought these things were supposed to run forever! Does this seem right to you guys? I bought the truck a year and a half ago and have always kept up with it. has dp tuner but everything else is stock. Smoke comes out of the oil fill tube slowly but doesn't send puffs like a locomotive. mechanic said the turbo is fine.

I bought an 06 6.0 f 350 4x4 dump bed cheap. seller said it was sitting for 1-2 years and wouldn't start. ficm is at 48 volts fuel pressure is at 100 oil pressure builds fine, then checked compression and reading no compression in any cylinder. My mechanic says new motor or possibly both head gaskets are blown.

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?

1999 F150 4.2... Has at least a bad #2 cylinder valve. Very low compression. 200k on the truck. Here's the question: drop another motor or just do the heads?
View 5 RepliesFord 6.0L Power Stroke Diesel :: 2006 - No Start Intermittently / Slightly Low Compression On One Cylinder
Started having some crank no starts intermittently. Scanned and found codes for cam sensor. so I was in a pinch and a hurry on a sunday so I picked up a BWD brand cam sensor from parts store and installed. I have not seen this issue since but started noticing other thing going on. I noticed a few weeks ago my truck was starting a little strange. as it would spin over before firing off, it didn't sound right. I couldn't pinpoint if it was due to slightly low compression on one cylinder or one cylinder had a little fuel or oil in it and that one cylinder was actually firing while cranking over.
I also was noticing a little longer crank times than normal. didn't matter if engine was cold or hot. sometimes would fire up quick and sometimes it took a few seconds. most of the time I couldn't catch it on my scanegauge if the ICP was low due to the lag on the scangauge.
Well one day on my way home from work (50 miles one way) I stopped about half way to fuel up. after filling up and attempted to restart the truck it really acted like it didn't want to start but did after cranking for about at least 10 seconds and started rough. and of corse my scangauge decied to hate me this day because it would show any data until I unplugged it and plugged it back in. so started home. felt like it had a very very light miss on the way home. when I slowed down to turn onto my road the truck died. took forever to get it to start back up. this time the scangauge was reading and I could see ICP was between 300-400 and IPR was 85%. so low pressure and not reaching the 600 needed to fire. once it started I limped it home. scaned it with my Auto Enginuity and it didn't show any codes.
So that much I can see I have a leak on the HPO system. but I done a lot of work to the truck about 2-3 years ago. roughly 80k-100k miles since the work. what I done included...
OEM oil cooler
OEM (updated)dummy plugs, standpipes & STC fitting
OEM head gaskets and ARP studs
BPD EGR cooler (I should have deleted)
ALL other engine gaskets(Bed plate, oilpan, front&rear cover, ect.)
OEM glow plugs and harness
OEM blue spring upgrade
Cleaned turbo veins
2 OEM REMAN injectors. (cant remember which two) had contribution codes one on each side.
This is all I can remember right now. Now have yall seen the updated dummy plugs and standpipes leak? I have not pulled valve covers to air test the HPO system yet.(don't have my air compressor at my new house yet). Here is what I have done so far:
Fully charged batteries.
I did do a bubble test. pulled upper fuel filter cover off and removed filter topped the bowl off and turned engine over using the wire by the passenger side battery. some bubbles but not a bubble bath.
Checked fuel pressure (not running) its 60psi. did not start truck because I need a different fitting so I can run the truck and check pressure while running.
while doing the bubble test I could hear that one cylinder is low on compression. but I do not have any misfire or contribution codes.
when I ran contribution test on AE its not showing any particular cylinder lower than the rest. but the line is not very solid at all.
Here is what I plan to do.
Compression test on each cylinder.
Looking at the Harbor freight kit. Looks like it has fittings for glow plug and injector holes.
If I can do compression test on both glow plug and injector holes this should show weather my injector orings are the cause of the low compression.
Then I have to airtest the HPO system and find the leak.
Am I on the right track? what else should I check? Guess I should add that the truck currently has 297K miles.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - White Smoke - Injectors / Lack Of Compression
I have a 2001 7.3 with 243k. I think the injectors are shot but other people including a local mechanic say it's not the injectors. What the truck does is smoke white. Sometimes little puffs when accelerating. Sometimes clouds that make the people behind you drop back a 100 feet. I have a ts6 on the truck and that alone with the 243k miles is enough to think its bad injectors. It smoke white. The exhaust is moist to the touch with soot built up like crazy. It doesn't really smell sweet and it's not really blue at all. It's getting horrible mpg. And lacks power. I don't have a high enough psi gauge to test compression. All arrows pointing to injectors?

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?
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smoking Brakes / Puff Of Smoke At The Front
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.

Ford 7.3L Power Stroke (1999-2003) :: P0269 Cylinder 4 / P0284 Cylinder 8 Running A Little Rough
So I did a cylinder contribution test and a buzz test today. It buzzed evenly on all cylinders. Then when I did the cylinder contribution test I got these codes,
P0269 cylinder 4 contribution balance
P0284 cylinder 8 contribution balance
It has been running a little rough lately but not smoking. Seems to be chattering more than it was too. I did the FRx, HPx, CVDs and banjo bolt mods about 500 miles ago and it was a lot quieter and ran better. Just recently started running rough and a little louder. Could these injectors be bad? I did new injector O-rings about 800 miles ago. I ran the test with the engine cold and with it warmed up and got the codes both times. It seems to have a little bit of throttle flutter when holding it about half throttle while driving.
As far as I know the injectors haven't been replaced and they have 186K miles on them.

Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 - Codes P1247 And P1248 / Noise Sounding Like It Lost Air Compression For A Few Minutes
My pickup has 316,000 miles on it. It's a 2000 ford f250 7.3 powerstroke. I have always bragged how my truck can pull anything because it has alot of power. Yesterday when pulling a 28' travel trailer up an incline I noticed I didn't have much power and it steadily got worse. Now I'm at a crawl when I hear a noise sounding like it lost air compression for a few minutes then the noise stopped. I stopped and looked to make sure everything under the hood was still attached and everything seemed fine.
I got back in and continued very slowly a few more miles home. Gauge were all good, never got hot. I put a scanner on it and it threw two codes. P1247 and P1248. I haven't noticed any unusual smoke. This is my second ford I've owned and know that when weather gets cold you may have to plug it in. But this truck it doesn't matter if it's 100 outside it will not start without plugging in for at least 1 hour. I've replaced all glow plugs hasn't worked. So I am assuming this break down now has something to do with it. I really am starting to not like fords!
Ford F-150 - 1997-2003 :: 1998 4.2 V6 - Low Compression Cylinder 2
Got myself into a tight situation with a truck I recently purchased and seeing if any of you have experienced the same thing or know what may be going on. I bought a 1998 F-150 with 213,000 miles and a 4.2 engine. When I test drove the truck it had a small chugging vibration, for lack of a better term, but the check engine light was not on and it seemed to run great while driving. No problem at highway speeds nor below.
On my way home the check engine light turned on which turned into a blinking check engine light and I knew I had been taken by a person with a diagnostic computer who cleared the codes. He made a comment about it turning on before but his "buddy" fixed the issue but I took his word because he seemed like a decent person.
I took it to a local shop and, if I remember correctly, error code 302 came up for misfire on cylinder #2. He changed the plugs and wires and it seemed to run a lot better. About 5 miles later on my way home the check engine light turned back on, but it still seemed to run smoothly by the time I got home.
The next day I took it back to him and this time we got the same error code plus (again going of my poor memory) error 174 which he said was cylinder #2 running lean. Earlier today he called and said he checked over everything and couldn't figure out anything wrong until he checked the compression. He said the other 5 cylinders were around 130 psi and cylinder #2 was at 75 psi.
Now this mechanic runs more of a brake and exhaust shop so his next statements are why I'm coming to all of you for your opinions.
He said the cylinder was shot and everything inside was shot including the piston, rings, and everything else associated with #2. (I don't think he got in there to really check it out) After scouring the forums I hear more people talk about the valves may not be sealing correctly and what sound to me, to be smaller issues than the entire #2 cylinder being toast.
I'm not sure if I am going to go after the person who sold it to me or not yet but I would like to see what others may think is going on before I light this guy up. I plan on taking it to a more proficient mechanic to do the work, if deemed worthy of work, but would like to kmow where I stand.
Ford F-150 - 1997-2003 :: 1989 - Low Compression In Cylinder 4
I have a '98 F150 with 4.6L Triton with low compression in cyl # 4 @ approx. 30#; all other cyl are at 140# or so. Would it be a burnt valve, bent valve, cam? Any harm if I drive it like that? I have not have it on the road yet.

So I got an IDM code and then after running AE buzz test got a P1273 (#3 cylinder high low open).
Ohm'd out the 42 Pin - got 3 across the board. Only test 42 pin from valve cover to injectors.

Swapped injectors
Did ford wiggle test.
Ran Injector buzz between all those steps and still get P1273.
What's the next step? Ohm from IDM to 42pin? May actually be a bad IDM?

So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong. Any way to check what's wrong myself?
Also just to double check, the cylinder number is 1, 3, 5, 7 for the passenger side front to back right? And 2, 4, 6, 8 for drivers side? And front to back means when looking at the front of the car? 2001 7.3 Excursion Limited with 232k miles...
