I forgot to mention that I also replaced the Battery and Altenator. The altenator seemed to have a stator that was not acting right when I got it bench tested. The guy said I could run it longer, but since I had it off of the truck it was my decision to replace it, so I did. I read on a few Mustang sites that the CEL with a P0340 code was caused by defaulty alternators. This did not fix my problem. As stated before, with the Cam Position sensors unplugged, the truck runs fine. I do see some hesitation above 3000. I am trying not run over 3000,since the VCT system is not working. I do not want to bend any push rods or damage the engine while it is running limp mode. Wish I had the answer, but it sounds like our trucks are having the same problem. I read here that one guy had his head on bank 1 rebuilt, and that fixed the problem. Does anyone know if the cab needs to come off to get the head off? Good luck.

Ya. This is sounding like the oil galley to the phaser is plugged with whatever!

Hate to beat a dead horse, BUT, I'm having issues with my 04 4X4 Lariat. I'm told it is the phaser on the passenger side. I had it replaced and the problem remained. I'm now told by a dealer that the head is stopped up and can't oil the phaser properly so no timing adjustments from the phaser. I also replaced the throttle body, the TPS and the cam sensors during this trial and error period. When I unplug the passenger side phaser solenoid the truck will idle but runs rough. With the phaser solenoid plugged in it won't idle at all and still runs rough. Truck only has 79,000 on it and I don't want to trade. However, the problem is starting to get to me. I ran sea foam in the crankcase and the gas tank on a trip to Florida last weekend hoping that would help declog and clean up/out. Nope. Situation normal, all fouled up. Help?

What do you guys think about just taking an air hose and pushing some air through the galley the VCT plugs in to?

What's the worst it could do? lol. It already doesnt work. lol

I have been trying Lucas oil treatment. I almost have 3000 miles on it. After 300 has been hit, I am going to change the oil and plug back in the sensors, hoping it may have cleaned it up. I wish FORD would recognize the clogging problem and send out a repair routine. One ford dealer told me to replace my Block with a longblock, that would fix it. At the tune of $8200 bucks. The truck runs fine with the sensors unplugged. Unreal. Great factory representation. Hell, I do not mind paying the $300 bucks to get the heads reworked, but I do not think it can be done by what FORD calls a in truck repair. I think the cab had to come off to get the damn head off to take it to a shop. I am very upset, to say the least. I bought the truck with 85000 street miles on it, 1 owner that I knew. At 95000 the missing and shuttering began. I priced it, for about $2000 bucks you could rework the heads and then add the thumper cam and a edge programmer for some real good horsepower gains. I put $2000 into troubleshooting to be no where. Disappointing. Keep me posted on how you guys are doing figuring out the problem.

Ok fellas, Here is another post I found where the guy is experiencing the same thing as us, only his is throwing P0345, bank 2 bad. It is a long post, but worth reading. Seems to be right on with my problem. I am planning on doing alittle more research, and then I will be back under the hood, checking out the timing. His was one tooth off....Skipped time.

Forgot to mention that the dealer also recommended that I get a new passenger side head, but then told me that that would increase the load on the drivers side head and cause additional problems, so maybe I should replace both heads. Then he follows that up with "or you could put in a new engine" like that's no big deal. After all this he said "if it was mine I would drive it till it quits". All well and good, but when is that going to be? Where am I going to be when it does quit? It's not a work truck so much but I do rely on it when I am using it and I would like for it to work if I have to call on it. I'm a struggling public servant and I don't have a lot of cash to keep throwing at this problem. New heads or a new engine ARE big deals to me.

Sorry for the whinning but as I stated in my first post "It's starting to get to me"!

replace both heads, seems fishy to me, but what do I know. Oh yeah, I know the 5.4 L triton should go at least 100K without any major overhauls. Hopefully Ford will figure out the jump time thing, if it is true. I have a print of when the Ford tech looked at mine and they actually asked the Ford Hitline how to check the time on my vehicle.....Unbelievable..........I think Hotline sent him to the flaretech site. I am thinking seriously about ordering a DVOM for myself.....if I can figure it out.

How about those Toyatas now...

I have an issue with my 5.4l
I feel like a bonehead, but I didnt mark the relation for the cam to chain or phaser relation when I removed it to replace it.

Can anyone give me a picture of how it's supposed to align??

Do I line the crankshaft up with TDC or the 1 oclock mark on the timing cover? Then how do I line up the phaser with the cam?

Thanks for any help.
