OK guys I'll admit I didn't read all 159 pages but I read a bunch. I had my mechanic install a new timing chain kit and phasers. Everything seems good except there is a rattle at startup now that I never had before. Definitely sounds like timing chain being loose for about a second or two. I spent too much money to have this issue so need to get to the bottom of it. He is saying that there is low/no oil pressure right at startup then builds up fine.
Is there a chance that one of the new tensioners he says he put on has a bad seal out of the box? He is basically saying I might need a new engine at this point and throwing in the towel. I guess there is always the chance that he did not even replace the tensioners. I wish I had the time to do this work myself but it's just not possible.
Thanks upfront for any advice/input you guys can offer.

If that saves you $1k from tearing into the engine again that would be worth it to me.

I have a 2004 screw fx4 which I purchased used recently noticed a ticking sound while idling after driving for awhile. My question is there any way to eliminate or to narrow it down to one or the other.

Phasers
Using the lockout kit you have to mark the cam phasers and the chain.
What do you do if your putting on new cam phasers???
This seems like a critical step to get right.

1 last time
ok guys, I just want to ask the forum one last time because I need to get this right the first time. 2007 FX2 Miles are 50k; My problem is the engine gets up to temp and then the idle retarding starts. My understanding is this is the cam phaser acting up. Only got a code 1 time and it indicated 1 bank. Never threw a code again but the problem persists.
My plan:
My plan:
- Lockout kit
- Change the defective spark plugs while in there
- Apply the new tune

Are you using an good oil filter like motorcraft with an anti-drainback valve? Even after the repair, my truck will do this for about 1/2 a second if it has sat for awhile. My advice to you if everything else is good is maybe try 5W-30 oil and prime the oil pressure before you start your truck if its been sitting for a couple days
If that saves you $1k from tearing into the engine again that would be worth it to me.

Sounds like one of your new tensioners is bad, or was installed improperly (over or under torqued)
