Knocking sound

Hi everyone!! I'm new here and new to owing a ford pickup. I bought a 2002 Ford F-150 lariat 4x4 as a project truck. I've always wanted a truck to mess around with, but once I got the truck home I noticed it had a knocking sound. It didn't sound like it came from the top of the engine so I checked the muffler first and found it had a 3" slit in it. I replaced it but the sound remains. Anyone here have any thoughts. I heard it could be lifters? Is that something I should mess with or not?

Is it louder when the engine is cold or warm?

Then most likely a exhaust manifold leak. Pass side usually goes first can you tell which side it's coming from?

Lol. It sounds like it's coming from the passenger side. Is it an easy fix?

No it's not easy from what I have read,, that's why I just learned to enjoy the nice sound as it's gotten louder and louder over the years. The 5.4 is easier to work on than the 4.6 which I have again from what I have read.

Now that you have a idea of what the problem is you can do a google search and read all about it and even watch it on utube.

My wife has had it with the noise,,, my fix was built yesterday, I should have it next week!

Wow!! That is a good fix and an excellent idea now for how I'll get my new truck... Let the noise annoy my wife. Lol! I plan on doing a lot to the truck it's my toy project till it dies. Keep checking I'll be posting updates of the truck progress. I want to see a pick of the truck when you get a chance. I'm sure it looks amazing. The 15's look tough.
