noise coming from cam sprocket

[SilSho95]

Like the title says, I have a knocking noise coming from the area shown in the picture. Can someone tell me why? What I might have to fix? I assume the timing chain may be loose. Any help is appreciated.

If it is a rhythmic tapping noise, that changes with RPM, then most likely your timing chain tensioner is in need of replacement.

It is a constant tapping noise. Can I buy a new tensioner from Autozone,or NAPA,or do I need to go through Ford? How difficult is it to replace?

I believe that both tensioners are obsolete. You may be able to have your local ford dealer do a search for you and find a new one at another dealer.

I'm having a tick/knock from that area too, but it happens every 2-3 seconds and it isn't a consistant sound.

As for as I know it just started doing this after I pulled the intake manifold off yesterday, I couldn't have dropped something in right?

mine does is it as well. its like, tick, tick, pause, tick tick tick tick, pause, well you get the point. i am assuming this is what youre talking about? i hope its the tensioner. if not rod bearings.

It'd not the rod bearing, thats at the bottom by the oil pan.

i know that, but even at that, some sound can travel through the engine, and you never know were its coming from. that was my point.

i tried the trick with the screw driver, were you put a flat head on the valve cover, and try to find were the tap is coming from. thats why i know mine is the tensioner. you can feel it through the driver.

Place a cloth on the valve cover and feel it. I felt the tick on my fingers.

Thing is I only hear it at idle, rev it a little and it goes away. Should I stop driving my car now or can I drive it a little bit?

thats exactly what mine does also. rev it and its gone.

Same with mine. The oil passage in the tensioner has crud in it. I've heard you can remove it, and clean it with choke/carb cleaner. Next time you hear at tapping at idle, turn on your AC. The sound stops immediately.
