That sounds like the plug wire is arcing. Have they been replaced recently? If not, change them. If they have pull that one off and look for signs of the spark leaking, usually either a burned area or sometimes what almost looks like some kind of white powder or liquid has gotten on it. It's a little hard to tell for sure because my dog pulled the wires out of my headset but it sounds like either the plug wire is bad and arcing out or simply not completely seated and it's arcing to the top of the spark plug. That would explain why the sound changes when you push down on it.

Sounds like the wire doesn't fully seat on the spark plug until you press down on it.. so when its in its regular position the wire isn't mated all of the way on the spark plug and is then arcing in the connection

It's either arcing or the spark plug is loose, pray its arcing if its been doing that for a year.

May also be a broken spark plug where the ceramic has separated from the base. Hard to tell in the video but the plug boot appears to be hopping a bit and that would indicate either a loose or broken plug. I've seen more than a few break and do that.

FYI technically thats number 2 an I just replaced that plug on my truck by far the easiest because you can look under the nissan stamped manifold and above the dizzy and see the plug. If you need help figuring out how to change it PM me I just did it last week.

Also wait til its dark and spary mist on that wire while the trucks running and see if you can see a hole in the wire thats arching.

It does hop a bit it feels like something is tapping it hard every revolution

Sounds like a arc it doesn't sound metallic to me. Maybe a loose crimp on the spark plug wire. Or the little terminal at the top of the plug is making a bad connection.


Does pushing it like that make it go away?

 

[Cameron23]

There is a physical knocking on it with every click. Like it feels like something is hitting it notice it bounces.

Maybe the plug is loose? An everytime it fires its jumping cause its loose?

 

[Cameron23]

Yeah but it won't stay pushed down

Did it do it prior to your valve cover replacement?

 

[Cameron23]

Glad you got it fixed Cameron. If you want to keep this open could you update your title and OP with something that would help people in the future. If you don't want to I can just close the thread whenever.
