My cylinder heads as well as the camshafts on my 2005 F550 are grinding down, now I need to replace them again, I bought the truck and had the same issue. I am just curious if the oil cooler is the one at fault since i just replace before I knew of the issue.
View 7 RepliesWhat are the torque specs for the crankshaft,cylinder heads and camshafts for a 2005 f550 v10 6.8?
View 2 Replies2005 FORD F350 Lariat 6.0, 61,000 miles, and in prestine condition. Just got the news the head gasket is blown! HOW DID THIS HAPPEN?!!! My mechanic says to scrap the whole engine because the 6.0 is the worst engine around. This truck should last for years!!!!!
View 14 RepliesI have a 2005 F350 6.0 PowerStroke, and I just did the head bolts upgrade to the ARP studs, new EGR cooler and a new stock turbo. Looks like everything came out good, no left over parts or unplugged connectors, all new fluids and fuel filters and oil filter. Did the priming of fuel and oil, the turbo. When it was ready to turn it on, I turned the motor by jumping the starter to build some oil pressure.
Now I turn the key to turn on the truck, it turns with no issues, it sound good, but it will not turn on.
Checked my batteries, they are fully charged, checked fluids, ok, checked oil pressure as I'm cranking it, it looks good.
It still does not turn on.
So, I jumped it with my friends Excursion, after a couple of tries, it TURNED ON.
Let it run for about 3 minutes then turned it off. It sound good just like it did before the upgrade, with an exhaust leak from the turbo.
Went to turn it on again, it turns but it will not start, jumped it again and it RUNS.
Now I let it run for about 30 minutes figured out where the exhaust leak was coming from.
Shut it off, Re seated exhaust pipe with leak, WENT TO TURN IT ON AND IT WILL TURN BUT WILL NOT RUN.
So what checks I can perform to start eliminating possible issues.....
(The truck is a 05 f250 with a 5.4l). The problem first started out with the engine temperature gauge spiking and then resetting itself when the truck is turned off and then turned back on. If I drove the truck for any distance it would go into limp mode and the CEL would come on. The code was p1299, which is the cylinder head temperature sensor, and I replaced the sensor but no luck. Then the shop and I went through all accessories hooked up and couldn't find a short until I remembered that my prodigy break controller would occasionally read "ol" or "sh" which both readings are from shorts. I tow a enclosed trailer about 85% of the time and the past week I have been towing it with a different 250 and the same break controller without a problem so I have eliminated the trailer. But the shop just said the problem was the controller and unhooked it.
Now the next day it threw the same code with the controller unhooked and the trailer hooked up. after thinking it seemed that it was happening when i accelerated so I took apart the 7 pin and sure enough there was a little water in it, but after driving it around for a little and no code being thrown I hooked my break controller up and it still was showing ol or sh so i believe there is still a short. Also I noticed that my voltage is reading right at 13v instead of the 13.8-14v it was reading before this issue arose. I think I have narrowed it down to the 7 pin harness and/or electrical in the break components, but do not know what would loop back to the temperature sensor.
2006 6.0 superduty showing low circuit codes on all 8 cylinders so i checked the FICM and it has 48v when key is on and while turning engine over. What to check next?
View 11 RepliesI just bought a 99 F250 Super Duty with the V10. When I bought it, I knew it had 2 misfiring cylinders (4 and 10) because it was throwing P0304 and P0310 (only 2 codes), but wasn't concerned as I've had to take care of my wife's Escape with it's misfiring cylinders. I replaced the 2 coils and replaced the plugs with Motorcraft plugs from O'Reilly's, cleared the codes and she ran fine for a couple of days. Now I'm getting an intermittent misfire, it's only occasionally throwing a pending code of P0300 which is "Multiple Random Misfire".
I'm fairly certain it's an issue on the electrical side because if it were an issue with the injector or injectors it would be constant regardless of RPM... right? As it is now, it basically does it between 55-65 while in overdrive trying to pull a hill or slightly accelerate. Once it's shifted out and the RPMs go up to 2k+ it runs like a champ... and it kills my fuel economy. The way it's behaving is just like when a coil is bad, but it's saying it's not identifying a specific cylinder (saying it's multiple) and it doesn't always do it (about 60% of the time).
I checked the MAF and it's very clean (looks almost new), checked the vacuum lines (those I found without a manual) and couldn't find any leaks and when I changed the plugs all the plug wells were dry.
SO this truck came into the shop yesterday with a really bad misfire. pulled the codes and got a misfire codes for cylinders 1-6 and also p1450 (unable to bleed fuel tank vacuum) and p068a (pcm/ecm power relay de-energized too early) i found a TSB related to the issue, TSB 10-25-7 i did as the tsb told me to do and pulled valve covers to check out the rocker shaft rollers and inspect for any signs of surface deformation or fatigue. they were fine on both sides.: ive got spark in all cylinders. fuel pressure was right around 55-60 the gauge was fluctuating pretty good. checked for bad fuel or water in fuel ect. fuel seems to be good. pulled O2s incase of plugged cats still ran like crap.
View 13 RepliesI have a 2009 f250 with 5.4l 3v. have had the truck only about 6 months. it started missing about a month after I got it. I replaced all 8 cops and all 8 sp. The truck ran excellent until 11/29, then I got a cel and the truck started running really bad. Found 3 misfiring cylinders. Changed all 3 cops again and that did nothing. Pulled the injectors and found 2 of them were clogged, replaced those also. Still no change was told by someone that the ecm/cpu may need to be reset, did that also. Still no change. There are no codes present but still has the multiple misfires.
View 9 RepliesI've got a 2015 F250 with a 6.2 Liter with no compression on 3 cylinders. The dealer just diagnosed it and has not opened it up yet but the mechanic says it is probably a broken valve spring...that it is not uncommon in this engine.
My concern is not repairing the spring my concern is what a "free spinning" piston in 3 cylinders does to the life expectancy of the main and connecting bearings in this engine. I have rebuilt engines in the past and I have bought re-built from auto parts stores and from Jasper and I have never had any last more than 60-70K miles. It seems to me that even with very little mileage on the engine with three of eight pistons jumping around under no pressure that there could be considerable scarring of the bearings or bearing surfaces. I am no expert by any stretch but this is an engine in atruck that has less than 22K miles on it and I ain't real happy about opening it up let alone trusting for the next 280K miles that the bearings have more wear on them than they should have. It was only driven about 20 miles total like this but that is a lot of pressure on a highly tuned and pretty darn precision machine.
This is the newest vehicle I have owned since 1988 and I meant for it to be the last pickup I drive (I drive 'em til the wheels fall off) but I am not overly confident that even if this is a one off problem that it hasn't caused even more damage that won't show up for another 100K miles or so???
I have a 2000 ford f250 5.4 2v that's been having a shaking at idle and no power what so ever. I tried diagnosing it myself and came up with nothing. I finally decided to take it to the dealer and they are telling me that the right side has no compression on 3 cylinders. They want almost 7000 for a new engine. I was wondering if it was possible to get away with just putting a new head on the right side?
View 13 RepliesI have a 2012 F250, 6.2L, Crew Cab, FX4 with a little over 77,000 miles on it. I bought it used from a Ford dealership last summer. Prior to now, I've only had one issue with it and that was squirrel/rodent induced. Something chewed through the wiring harness right before the connection to the #7 cylinder. There was enough left over wire to solder it back together and put heat shrink around each wire.
It ran fine up until last weekend. The wife and I went to a store, she was driving and parked like a total jerk right in the front area of the parking lot. When we got back in the truck, she started it up and it was just running rough with hardly any power. My first thought was someone dumped something into the gas due to her amazing parking, but there were no smells or residue of anything near the gas cap when we got home only a couple miles away.
When I got home I ran my code scanner and found 300, 301, 305, 307, and 308. I dumped a bottle of ISO-Heet in it, let it sit for a bit then cranked her up and ran it for a few miles to the gas station and filled up...about 25/26 gallons, I don't remember...I was a little above 1/4 tank when this all started. No change in performance and the codes were all still the same. I pulled the MAF, it looked clean, but I wiped it down anyways and threw it back in. No change. I then changed all the plugs. This took care of 301 and 305 but 300, 307, and 308 were still coming up. I then picked up two new coil packs for cylinders 7 and 8, threw them on and still no change.
I sat with it running on a flat surface for a little while revving the engine randomly for about 15 minutes, during this I noticed a fast tapping noise at about 3400 RPM, it went away quickly with no changes in the gauges on the dash. I cant really tell where it's coming from, but kinda sounds like its under the middle of the truck. While sitting there I ran the codes again, and now its back to 300, 301, 307, and 308. I'm now at a loss of what to even look at...
I've also checked the voltage coming off the harness at the connector to the coil packs...just under 11 volts. I've searched all over for what that voltage is supposed to be, but have failed miserably in my searches.
1999 F350 & lately if I don't plug it in even if it's like 40 out for like the first 30 sec sounds like its only running on 4 cylinders than it'll just even out & alls good. thinking glow plugs here. I did replace them last fall unfortunately with the cheep ones that I been now reading bad things about.
View 2 RepliesI got to replace mine because the hood won't stay up on it's own and is heavy to lift. I was wondering if these things fail often. Mine is an '08.
View 5 RepliesNew plug on right, lower bank 2 plug on left
Started getting a P0300 and various misfire codes for random cylinders. Truck has 95,000 kilometers so figured I would change the plugs. Several of the plugs on the lower bank on both sides were pretty much toast. Most of the plugs on the top looked good. All of the plugs had a small deposit where the spark hits the ground probe. Picture is typical plug from lower side. changing the plugs should make a big difference in how she runs and eliminate the codes.
Took right on 4 hours same as dealer said it would. I would have got it quicker but it was not a race.
Alright, so here's what I've got: 2002 Ford F-350 7.3L - Unmodified, Stock, no chip, no tuner, 130K miles, been run with off-road diesel most of its life as a farm truck.
Here's what it's doing: Serious misfire in cylinders 4 and 6. At idle, mild miss. Throttle from 0 to 50 percent, runs well. Throttle from 50 percent to 100 percent, heavy miss, chugging, white smoke out the exhaust.
Here's what we've done so far:
New UVC Harnesses with updated pigtails.
Cleaned Fuel Filter Mixing screens.
Cleaned out fuel tank.
Cleaned bowl.
Changed Fuel Filter.
Changed IDMs
Changed Crank Sensor.
Inspected injectors while running to see if oil is pumping (it is).
No improvement. Where to go from here. Pulled codes, and it says Cylinder #4 and #6 High to Low Side open. We don't know what to do at this point.
how difficult is a in frame head gasket repair?
View 6 RepliesBack Story: Ok so in my infinite wisdom I let myself get distracted when I was looking at an 01 F250 V10 Crew Cab. I thought, it needed all new breaks/rotor & 2 calipers. And new carpet and seats, then I would have a good hunting rig.
So I went and looked at the truck in the dark (first mistake). The guy was very honest with me and told me about all the body and interior issues. Even informed me of the caliper that he disconnected because he could not afford to fix it. He informed me that it did burn a little oil and it's been a while since he checked the oil. Well at that point I was going to look under the oil cap to check for any milky residue. Well I got distracted (Second Mistake).
So here we are 2 weeks after getting bringing the truck home. I already replaced the carpet and seats, breaks & rotor & 2 calipers. Well today I decided to go get some new oil and a filter, and do a quick oil change since who knows when it was done last.
Issue:While draining the Oil it seemed like there was an abnormally large amount of oil in this engine. (See photo of bucket full of oil from this rig.) Well didn't think much of it and swapped the filter. And went to add new oil to the engine and found that under the cap was some milky substance.
The V10 has 420K original miles. I have heard that is no big for the V10 but thought it would be good to note this detail. Questions I have: Should I get some kind of test kit to confirm it's a blown head gasket? If so what kind of Kit should I look for? Do you think this truck is worth replacing the head gasket?
Any chance this may just be a known issue for the V10 and I just need to replace some kind of valve? I could not find any you tube videos of a head gasket replacement on a V10 any thoughts where I should look?
My Skills: Just to be clear I don't know anything about the V10 motor. I have a 94 f-250 but have never had to dive in to a head gasket replacement before. I have done a head gasket replacement on smaller engines (IE: car and a jeep) but those were obvious that they had a bad head gasket.
I've been trying to figure out what is going on with my '99 F-250 V10, you can check out this thread for the back story

I did a compression check and the results seem inconclusive to me- see image.
Before I did the compression check I started to take the intake manifold off to change the gasket set and it's about 50% done. I'm at a crossroad now. Do you think I should finish switching out the intake gaskets or do you think it's more than likely a head gasket? I would hate to put it back together, it still smoke and have to take the intake and everything else back off to do the head gaskets.
Someone had mentioned a possible small crack in the cylinder wall that is closing up when the engine gets heat in it and obviously doing the intake and cylinder head gaskets would fix it if that's the problem.
I thought I needed a head kit my truck runs and drives great till I run out of coolant no smoke doesn't get hot I run out of coolant I lose my turbo. Pull over fill it up I'm back to normal I just noticed I have sweat marks on my water pump pulley.
View 6 Replies2001 Ford F250 5.4 gasoline. At the most recent oil change my mechanic said there was an oil leak and he had dyed the new oil and cleaned everything up and to come back in 100 miles.I just did so and he said that it was a leaking head gasket. He said to do the head gasket replacement right or to put in a rebuilt engine would be close to same and he would recommend the replacement. He said it was not a heavy leak and probably ok to drive another 10,000 or so miles first. Just returned from a trip where we drove 15 hours straight (30 degree temps) and the truck ran fine and no overheating.There does not appear to be oil in coolant or vice versa. I took the cap off overflow coolant and cranked and revved and no disturbance whatsoever. I read somewhere where a mechanic was saying it was impossible for this Ford engine to leak oil from a head gasket failure .
