I just returned from a long weekend in Detroit, where I enjoyed the largest, best automotive event in the USA, the 10th Annual Woodward Dream Cruise. I towed a 65 Dodge Coronet on an open trailer and a Ford loving friend towed a 66 Shelby GT350 in a 24’ enclosed trailer using his Edge w/ Attitude equipped 2004 6.0 liter F250. We drove 75-85mph the entire way home, he had his edge set on level 2(or so he says) and I had the TTS Tow Tune installed in mine. He could pull away from me at 60-70 mph which was a disappointment but the real disappointment came after I got home, unloaded, and let the truck set for 30 minutes. Before anyone asks I let the truck idle for 5-10 minutes in the driveway before I shut it off. Well 30 minutes later I start the truck to pull it into the garage and what the ?????? I now hear the worst knocking and banging sounds I have ever heard, and I have heard a few rods exit oil pans on gassers before. So I shut it off and check under the hood, nothing out of the ordinary so I try it again, same thing so I bring it off idle and the knocking seems to get less but there is a serious miss and shake going on. So I drive it into the garage and notice it is smoking like a worn out freight train, not oil smoke but diesel smoke. Bummer! This morning I call the service manager and tell him my problems and he says “I need directions, I have a rollback there this morning”. The dealer is 75 miles from my house and I told him I really needed my truck this week so he sent a rollback out with a 01 or 02 2500 4x4 for me to use. Awesome service by my dealer but what the ?????? is with this thing. This is the second time I had to call the rollback, the first being an injector pump failure. The ford freak had to rescue me that day which really sucked! Now he has me twice, which is really just in fun between friends but what the ??? I hope it’s just an injector but would not be surprised if something in the valve train didn’t call it quits.

No SES or MIL lights and I reinstalled the stock ECM and plugged in the EGR.

At least I made it home, what do you guys think?

Sorry to hear about that. Sounds like an injector from other posts I have been reading. If that is the case hopefully they can find you an injector quickly and get it installed quickly as well.

Good luck.

Injectors ,I hope GM doesn't drop the ball on this. I will notice mine occasionally will get load but settle down.I find when the injector balance gets up around -5 they can get knocking. Number 1 and 8 are the ones I'm seeing.

I need to get a scan tool so I can keep an eye on things and reset any codes that may come up in the future.http://www.dieselplace.com/forum/smileys/Ermm.gif

I noticed two symtptoms leading up to this

1)2 or 3 times this past weekend, after cruising at low speeds, 30-40 mph, mainly while returning to near idle conditions that the engine whould go into a slight rattle or stumble for a fraction of a second and then clear itself up and return to a normal idle.

2)5-10 times while at cruising sped the truck seemed to develop a miss, hesitation or stumble that seemed like it shut off for a fraction of a second. Not enough for a passenger to notice but enough that I could feel it.

Later on Sunday, my girlfriend mentioned my mother heard the engine knocking when I started it the first time and asked her if that was my truck and if it was normal, they were inside my house!http://www.dieselplace.com/forum/smileys/Ouch.gif

I will ask the mechanic what the balance rates look like.

Barring a bad injector, this sounds a lot like what some people have described when their Edge went bad. Timing issue. Bad connection to the cam sensor? Bad sensor?

Just spoke to the service manager, because we were both busy he didn't go into the details but he told me they were going to have to remove a head! What the ???? The engine ran fine with the exception of 3 or 4 very quick rattles(1 second long) that disappeared as quickly as they appeared just before I shut it off for approximately 20-30 minutes. Could a stuck injector allow the fuel remaining in the rail to leak into a cylinder causing a particular cylinder to hydraulic upon up? I have never seen an engine come apart upon startup.

JK's open house is getting close, I hope they get it sorted out soon. http://www.dieselplace.com/forum/smileys/Angry.gif

Any other ideas?

Here is what I know so far. A new long block and 1 fuel injector are on order from GM. #7 cylinder had 0 compression and after removing the head it appeared something had been run through that cylinder. This obviously beat up the pistion, head, and valves however, no broken parts could be located and the mechanic said the turbo looked to be in good shape. I am going to try and get some pics of the damage and I also want to know the cause of the failed injector, did it stick or did it get beat up? I will also mention the design of the TTS muffler is such that if something made it through the turbo it may have been caught inside the muffler.

The injector may have stoke and that is what caused the damage. I doubt something went thru the turbo unless it was a piece of turbo blade.


Again Volunteer no info why open a window. The have diagnosed the problem and it is being warrantied.

even if something went through the turbo it would have to go through the cooler before it got to the engine. Just doesn't seem likely. I would go with the injector falling apart. Man, what are the odds?

The engine isn't that old. A loose part from manufacture in the intake track would take an indeterminate amount of time to make it to the cylinder. The Aluminum head should have taken a good impression of the loose piece.

The new engine is in! I picked it up last night and while I was there I took a look at #7 cylinder. The piston had several small nicks and indentations and the valve guide appeared to be damaged but the valve looked ok. The mechanic had never seen anything like it before and what ever it was could not be found anywhere. I will try to have some pics taken before it gets crated up and sent back to the factory for analysis. The new engine seems to be quieter, smoother and best of all better fuel mileage. The engine included all injectors and rails but unfortunetely no turbo. I hope to compare it to other LLY's tomorrow at JK's.

Racehemi...did they mention anything about your cat being removed or did ya bolt it back up before you took it in?

I left the cat off and followed Mackin's suggestion, I kept my mouth shut and didn't volunteer any info. They figured it out but didn't say a word. The install looks very clean and professional however I left a few drops of oil on Johns floor so it looks like they have a few things left to iron out this week. The motor definetely gets better mileage and is quieter. I will let John post the exact numbers but I believe my baseline was 265rwhp, can't remember the torque. That's with 400 miles showing on the odometer, no cat, 4" TTS exhaust and an amsoil air filter. She's definetely broke in after Saturday afternoon! http://www.dieselplace.com/forum/smileys/Big Smile.gif
