Slight Knocking sound at start up

[thefracdaddy]

My Raptor is 4 weeks old and has been off roaded quite a bit. I noticed a slight knocking sound coming from the engine right after I start it up. Any idea what is causing this sound. I havent had any issues with the engine performance or 4wd at all, just a slight knocking sound. Opinions?

Make a video, upload it to YouTube and then post a link.

I went outside to record a video, started the truck and......... no knocking noise. Thats about how it goes. If it decides to start making that noise again I will be sure to record a video of it.

its pretty normal... you wouldn't think so but it is.

Mine does the same thing. It goes away as soon as the oil pressure builds within about two seconds. "It's normal for these engines nothing to worry about". At least that's what ford told me. I cringe everytime I hear it.

I get the same knocking sound every morning at start up. It goes away almost immediately.

Yup I get it occasionally too. Sounds like an old GM motor with a thrown rod for 2 seconds.

There's an oil additive called power punch. It keeps the oil up on top and prevents dry starts. Most new fords do the knock. My truck does it too. The punch stops it.

Thanks for all the input, I will be able to sleep soundly tonight knowing that im not the only one with the knocking sound. I guess im a little gun shy because the 5.4 in my old truck started knocking and 3 weeks later kicked the bucket. Costing me 4k and 3 weeks without a truck.
