Guys I just purchased a 2018 5.0. It has a very strange sound. I want to make sure it’s nothing serious or maybe it’s normal. I can’t really describe it. It’s like a ticking rattling sound. I took a vid of it, please chime in.

That all sounds like the direct injection fuel pump to me.

Try taking a video from the bottom under the oil pan area. If there's a dull thud sound under there, it might be piston slap.

What I hear in your video sounds like the underhood DI fuel pump.

Is it suppose to sound like that?

The DI fuel pump makes a loud ticking sound that can be heard from above the motor and is in relation to rpm since it's driven off of the camshaft.

So I got nothing to worry about then? It was driving me crazy. I’m a bit ocd when it comes to noises.

Well...if you take it into Ford, they will say its "normal"

. This 5.0 is sure super noisy. I came from a Tundra and that motor was dead silent. One thing though the acceleration and performance of the truck is night and day compared to 4.6 V8 I had.

If you’re talking about that inconsistent metal on metal clicking sound, no that doesn’t sound normal to me. And that’s coming from an 18’ 5.0 owner. Many of us on here would be comfortable saying you picked a not so great model year to buy the V8. Best be keeping an eye on your oil level and familiarize yourself with the oil consumption thread on here. God speed!

Yeah that was the first thing I did since it’s still under warranty. I’m doing an oil consumption test on it now and had the pcv valve replaced since it was making noise. The only noise I couldn’t pin point was this one. Which are those clicks. The diesel noise it makes looks “normal” since all the ones I’ve heard make the same sound. I kinda wish I would have gone with the 2.7.

I would say that is common with the 5.0L. Does the volume of the noise change when fully warmed? If it goes down, that would suggest it is piston slap.

My 5.0L sounds like that but when fully warmed the engine quiets a lot.

If you really feel compelled to do something, you can add Ceratec and that will help to quiet the engine.

I recommend you just enjoy the truck. Worry about why the fuel gauge seems to always go to the left.....
