Hey all, new member here, don't meen to intrude, but figured I would take this time to intro. have been using this site for info. for some time now and love it. Thanks to all for the tons of knowledge. I have had my XLT Screw 5.4 for about 12k miles (6 mths) It is currently on its 5th trip to the "stealer" for the cam phaser prob, and many others incl.; throtle responce, rough idle, badges peeling, vibrating in wheel and brke peddle, poor power, pretty much every issue discussed in this forum. The first trip they said they could not dup. the prob. and said that the vibrating was because of the cheap tires they put on it from the factory (continental conti-trac). I went and replaced the tires anyway, P265/70 R 17 Bridgestone Dueler AT Revo's. Second time they said the parts had to be ordered, took a week or so, third trip fixed issue, picked up the beast headed home, ( I live in Austin, Stealership almost in San Antonio) noise was still there when pulled in d-way, Fourth trip they did the fix again, fixed the prob. for about two days, Third day I went to start her up heard a weird crak noise when satrting and voila the noise is back. The last time it was in they also got my new badges in and replaced them, left about a million metal deep scratches all around each badge ( fenders and gate). I have made all the proper managers and others aware of the issues so we will see what happens, they said I sould be able to pick her up on Thur. or Fri. Hopefully all will be good. I also have been getting free loaners!

Sorry for the rant but I guess it just depends on the dealer as to how long or even if it will be fixed.

Also, not to hi-jack but my dealer told me that I had the most current flash for my PCM, My build date was 03-05 don't know a spacific day, and has not been flashed again to my knowledge, But I read in other threads that the pcm flash was mainly for build dates before 04-05 which would include mine. can any one give me more info on the spacific program that the new reflash consists of, so I can maybe lead the service guys in the right direction Would be glad to move to GD But any info would be greatly appreciated TIA. promise other posts wont be near this long and boring, just a little frustrated

want to do more mods, but dealer is kind of a ****

Tires are only other thing done yet

 

Hellbound.... well???

What did they say? They gonna fix you up!?

 

I had mine done. What a mistake. The thing hesitates real bad. Lost about 3 miles to the gallon. Took it back three times so far and they keep telling me I have the "lastest and greatest" setup. Well if this is the greatest I'll go back to my 1967 international scout. A friend of mine went to a differant dealer after I had mine done and they told him the didn't have to tear the engine down, they readjusted the timing through the computer and the noise is gone and gained 2 MPG. I'm going to try a that dealer and see what they see what they can come up with. Right now,I hate my truck. Before warranty work it was the best thing I ever owned. By the way it took 2 weeks and tearing the engine down 4 or five times to get it running again. And.......it's still not right.

 

Wow, that's freakin crazy. It took them twice, but they did finally get it right. Mine actually seemed more responsive since the fix. Only thing is sometimes I notice it "pings" very lightly sometimes under a very heavy load while it's hot outside (kind of like the timing is advancing too much). May be in my xcal tune... not sure

 

Well, after doing alot of reading and research and listening to my truck idle while hot for nearly an hour total, I have concluded that I also have this cam phaser tick. Its very noticeable at drive throughs(really embarassing in a $30k truck). I tried to narrow down the tick, I can really hear it in the wheel wells and seems to be coming from somewhere under the valve cover. It only does it at idle under 1k RPM and goes away at higher rpms. I guess I should take it in to the dealer, they know me by name now and Im a regular as many times as Ive had the truck in. I never get to drive my truck as long as the dealer has had it. Guess they could try to fix my Scab door rattle while its in also, and even more so fix the vibration at idle that is annoying as hell. LOL, listen to me, the dealer fix 3 issues with one visit, now thats being unrealistically optimistic.

 

Sure it's not the injector noise? All these trucks have the injector noise....

It's little more of a deeper sound... mine was coming from the passengers side (before it was fixed).

 

If it was injector noise wouldnt all the injectors make the sound, and not just one of them? The sound is really much louder than injectors should really be and it sounds more like a rattle. If it was injectors wouldnt also the sound continue with RPM speed, this sound stops at RPMs above 1000 or so.

 

Does it do it when its cold?

 

I ask because mine was barely noticable when I first started it up. When it warmed up it became noticable.... worse the hotter it got but going away when I revved the engine

 

No, it does it when its been running 15-20 minutes. I parked beside a wall to hear it better when in the cab and it goes away when I increase the throttle.

 

Sounds like the "cam phaser knock" ......

I'm kinda like Hellbound, what the heck makes it "knock" anyways?? Wish someone could shed some light on this

 

the cam phaser knock as explained to me is that there is two gears that control the timing chains that are under the timer gear cover (front of engine behind the water pump). These two gears are manufacturer defects, they are not cut properly. The repair is to replace these two gears. When the engine is running these gears are moved slightly by the sensors to adjust timing, and this of course is all done by the main computer. Personnaly I like the old "turn the distributor" but that ain't happening no more.

 

Id love to have my old OHV windsor engine back, these mod motors just dont have the reliability the old windsor engines had, period. Im just not sold on these mod motors, they tick, shoot spark plugs out, sieze them, did I mention tick, and dont impress me on power to be honest. I was hesitant to buy a Ford for that very reason, but figured that all the bugs would be worked out with these Mods engines, but new problems seem to constantly present themselves. Oh well.

 

a cam phazer actualy controls phazing between intake and exhaust camshaft lobes . our camshafts are two peice with intake lobes on one part and exhaust onthe other kind of like a metal rod inside of a pipe. the phazer changes how close and apart they open and close intake and exhaust valves.advancing and retarding the entire camshaft is done also but seperately from the cam phaser . i dont know if its the phazer making knock sounds or valve train components but its a loose sounding knock so its probably the phaser itself . my truck makes the knock, its embarasing as hell somtimes

 

i will report how mine goes. have appt. this tuesday to get that done and the fan clutch, as well as a few items not fixed to my standards after the accident.....the dealer i am dealing with is cleaning up someone else's work. all in all good, just need some things ironed out......but will let you all know....will be awhile because of a few parts also needing painting etc.....
