I am going to be replacing the cam phasers, timing chains, oil pump, adjusters, and guides on my 06 5.4. Is there anything else to look at replacing while I'm this far into this thing. The problem is that it keeps giving me a p0012 code, I have swapped the selonids and cam sensors from side to side with no change. Thanks in advance

 

Clean out the pan - you will probably find debris in it.

 

Seconded. And probably replace the oil pickup tube. Mine had a lot of plastic from the guides/tensioners clogging it up.

 

Update. I replaced everything the only thing that was obviously wrong was one of the tensioners was wore out. It's quiter than ever

 

How much did this set you back?
How many miles did you get on the OEM set up?
Not there yet with mine but thinking ahead..

 

Truck has 126000 miles and the parts cost $1100 at napa

 

Thanks for the reply.
When the time comes, I will have to get a mechanic to do this work for me... $$$

 

Mine made it to 232,000 miles before issues. So you may have a long wait

 

I got quoted 1400 without changing the oil pump. They said the motor had to come out to change the pump I did it without removing the oil pan. It's a pain but you can do it

 

Wow! Pull the engine? Never ceases to amaze me - the mis-information from what should be trusted sources.


But - on the subject of the Pan. IMO, once you are that far in, and considering the pan is not as hard to pull as the passenger side valve cover (especially on a 2x2), it is a mistake not to do so.


If you have broken guides, almost certainly their will be pieces lodged in the screen on the oil pump pickup tube. That can result in (even a new pump) cavitation - (whipping up air bubbles). Air bubbles in the oil galleys compress, unlike oil, and that negatively effects oil pressure. I believe this leads to intermittent (phantom) symptoms of chain tensioner / Phaser failure after an otherwise perfectly done timing chain job.


It's not worth the risk and it is not that much trouble. A very good "HOW TO" on removing the oil pan on a 4x4 is here posted by @nu-supercrew:

Good luck
