Ticking Sound From Motor

[acolic]

Hi

I have a ticking sound coming from the motor of my 99 Ford expedition.

If it I didn't know better I'd say the rocker arms were loose but I don't believe the Ford expedition has rocker arms to adjust.

The ticking sound gets faster as I pick up speed.

Sorry I can't be more specific except it sounds like the ticking sound is coming from the top of the motor.

Any suggestions?

these expys are knowed to have exhaust manifold problems cracked or bolts rusting and snapping off sure it's not just that ?

could also be a spark plug issues

To check if it is an exhaust leak, go to both front wheels and listen if ticking gets louder , an exhaust manifold leak sounds pretty close to a lifter ticking.

You might be hearing the lifters ticking.

Are you low on oil?
What oil are you using? 5w30?

I found most lifter ticking was caused by low on oil or needing an oil change that was way over due.

Check all spatk plugs for proper tprque.

Had similar issue. Was really noticeable when going through drive throughs or other areas where sound was echoing out the wheel well. Ended up being a loose spark plug. Unfortunately it was doing it long enough to crack the plug. I replaced all 8 with new motorcraft plugs.
