I had those changed as well. Didn't help.

I found this while "surfing the 'net".
The cam phasers were redesigned a few years later so that problem has gone away but it was pretty common back then. The only way to check for proper oil pressure at idle is to remove the oil pressure sensor and temporally install a gauge. Oil pressure must be read with the engine hot and idling.
I don't think the cam bearing "issue" was that common.

Quickly Diagnose The Most Common Fault on Ford 4.6L & 5.4L 3v Engines
What a bad cam phaser sounds like.
Another not real common valve train issue is worn roller finger follower. A ticking/clicking noise but probably not as loud as the phaser.
If either of these are diagnosed, and especially if the timing chain/tensioner needs replacement, I would have the oil pump replaced also.

He replaced the solenoids and it didn't change anything. He also promised I would have it this weekend, but forgot to leave the keys in it so I could pick it up. I'm getting it back Monday and taking it to someone who can actually fix it. At this point it has spent more time at the shop than my own driveway.
Glenn, I'm sorry to hear about all of your problems. I just read through the entire thread. Part of the problem is probably Cam Phasers. They are locked at idle by pins operated by the solenoids (that you already had replaced) oil pressure operated the cam phasers and the biggest issue is keeping them lubricated at idle because the oil pump isn't a high pressure pump. Once the engine comes above idle the solenoids pull the pins and then computer determines whether to advance or retard the timing as needed. (this explains why it works better at higher speeds.
I know you aren't going to do the work but here are a series of 4 videos that explains how it works and how to change the cam phasers and timing chain. He is a great teacher and you will really get a good understanding of the cam phasers, how they work and what they do.
My personal opinion is that an engine that has 180,000 miles on it is shot. A lot of people have trucks with 250,000 plus miles on the engine but ultimately you are building a new truck from spare parts to keep them going. It might be a better option to get a new engine or newer engine with a lot less miles and drop it in. I got rid of my 05 with 146,600 miles because the dealer said I would need cam phasers and timing chains in another 20,000 miles. It was ticking at idle and I could tell that it was getting worse. (Plus the body was rusting out really bad and that was one of the major reasons as well.) We do a couple of 1300 mile trips every summer and we just didn't feel comfortable driving it long distances any more.
I hope the videos help. Lots of good information if you really want to see why its a $2,000 job.

I don't know that I would say it was "shot", but if anything under the front engine cover is and, you should replace all the components ! Cam phaser, timing chain, chain guides, tensioners and the oil pump (pay the up charge for a Melling high volume oil pump).
Keep us posted !

I took it to a Ford dealer this morning. The tech said he has to replace two more solenoids. $650. Ouch. Fingers crossed - I have to get lucky at some point. Dropping a new engine in the thing is at least $5000, and I just don't have that.

The parts are about $110 each on rockauto.com and from what I've seen they aren't too difficult to change.

Hello Glenn,
I wouldn't waste the money if I were you on this truck. I had an 05 with constant cam phaser issues. Many trips to the dealership to resolve under warranty until I got tired of dealing with it and Ford must have too because they posted a TSB saying it was normal to hear marbles in a tin can coming from the engine at 1200 to 1800 RPM. Then it would stall or rough idle whenever it felt like it. So I did the smart thing after that..I disconnected the right bank to eliminate the phasers...ignored the check engine light...went back to a 1st gen expy...and traded the 05 for an 09 CTS. Save yourself the pain.
Chris, my 05 was going strong at 146,000 miles with a slight tick at idle. I never had the marbles in a can noise. I think your experience was atypical not the norm. There are a lot of 05 guys that have had minimal problems. It sounds like you just got a bad one.
