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.

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

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