My 2013 Ford F-150 lariat Ecoboost has a rattling noise that makes it sound like a diesel I have know codes came up and the truck still runs great I can figure out the problem is

 

Welcome to the forum. Have any video? Throw it in YouTube and post the link here for us.

 

vibrating buzzing sound from passenger side, exhaust manifold leak & gaurnteed broken exhaust manifold bolts...

Just a guess....

Or its toast & rod bearing failure...

 

It's rattling in the center of the truck at front of the engine

 

If it does it mostly when you first start it up and goes away when the truck warms up. It’s most likely the timing chain and gear. My 2013 did it when I first bought it. Used of course 4 years ago. Luckily I had bought an extended warranty and it covered it. Unfortunately if you don’t have a warranty. It’s expensive. Sorry

 

Flood start ur truck when cold. 5 seconds should do the trick.
check bolts on downpipes.
turbo has a flapper in turbo

 

Ok thanks my noise doesn't go away but truck runs great I don't have any engine lights or codes coming up

 

How do I flood start truck when cold 🥶

 

hold ur accelerator to the floor, start truck as usual, the engine will turn over but not start. After 5 seconds just lift off pedal and truck will start as usual.
this a noise eliminator for timing chain issues and some F150 are dry on top. Oil drains back to the pan.

let us know how that flood start Worked you should also flood start right after oil change!!
