Clanking/rattling when revving or starting engine

[dmac]

Has anyone else had this rattling sound on their F150? 5K miles powerboost built on 4/22.

I really hope this is just a loose heat shield/engine mount, and not anything engine related.

Hi there! Go ahead and send us a private message with your VIN and approximate mileage, and I’ll look into this rattle concern for you. Thanks!

Update:

The dealer stated the rattle is coming from the catalytic converter, which they need to replace. Unfortunately, the part is on back order, so I am going to get the truck tomorrow until the part comes in.

I have a rattle when the engine first starts up from electric. This only seems to happen after it has been sitting for awhile.

Sounds like a heat shield, so a cat sounds plausible (if expensive.) One way to isolate these rattles is to tap the exhaust (and surrounding parts, heat shields, hangers) with a plastic mallet. A quick silencer is find a spot where jamming a piece of plastic stops the noise, then replace the plastic with a piece of hard silicon (it will hold up to the temperatures) or a careful dollop of RTV using a spudger as needed to work it into the offending rattle gap. Can be a permanent fix or just a sanity saver while waiting for parts. : )

Hey I was just wondering if replacing the cat fixed your issue? I have a 22 powerboost and it’s making the same exact sound when the engine kicks on. Mainly does it when cold, but occasionally it’ll do it while driving slow thru a neighborhood.

It did fix the issue. Good luck.

Hello there! Just a quick question about this noise. I’m having something similar on my truck. Did it go away when the truck warmed up/was driving around for a bit?

Could be an example of the heat shield noise.
I recall a few people posting about this sort of noise, especially on cold starts.
My "diagnostic" method is to get on a crawler and push things with the handle of a hammer till I find something that changes the noise … : )

Ok thank you! I’ll try doing that. Hopefully I can isolate it and fix it! I attached a video of the sound for reference.

That sounds similar. I think it's an exhaust heat shield.
Or the transmission is empty.
Kidding! : )
But I did read about some people receiving their truck a little low on trans fluid. I checked mine, just in case, but a dry trans sounds quite different and there's a warning light. : )

Ok perfect, I will be taking a look to see if anything is loose. It usually becomes intermittent when the truck is warmed to operating temperature. More noticeable in a parking garage. Yeah there is no warning light and the truck runs ok as well for now. Thanks!
