4.0L SOHC 2010 Ranger making noise when idling

[Kingkrush]

After looking forever finally bought a 2010 4l ford ranger sport!!

Like buying any used car at this age some quirks are slowly starting to reveal themselves. My main concern is that the truck seems to be making this vibrating/ticking sound as it idles. I first noticed in a drive thru with the window down when I had my foot on the brake and have continued to notice the sound mainly when idling at a red light. Shifting into neutral and park the sound completely disappears.

Its got around 120k miles and everything else seems to be running smoothly going to take it into a shop soon but after being on enough forums starting to freak that it could have anything to do with timing chain…

Hello Mr surprise Pikachu.

Auto or manual?

Also, timing chain tensioners on the late engines are nbd. I just did mine. Again.

Get motorcraft ones from a dealer and make sure you order the gasket washers.

Preload them like a hydraulic lifter (pump them up submerged in a jar of fresh oil first, they will get rock hard) and install. Back one is super easy if you take the passenger wheel of. Front one... eh. You can sneak it out if you really want to. Taking the intake off is easier.

I'll give you the parts list if you're going to do it. At 150k I would.

Automatic.

Appreciate the write up! Sounds like a job I can handle once I’ve got a free weekend and the weather cooperates. Passenger wheel off for the back one and the intake off for the front, noted.
I’d love the parts list whenever you get a minute.

Thanks again.
