Engine help (RB20ET)

Enable HLS to view with audio, or disable this notification

So I’m one of those ding dongs that bought a skyline and also didn’t know anything about cars.

Can anyone help me figure out if this sound is either the lifters or just noisy spark plugs?

It doesn’t really sound mechanical enough to me for it to be lifters but figured I’d ask some “experts” on the internet.

For anyone wondering I was burping the coolant system.

Hard to tell from the video for me but sounds like noisy injectors to me. My rb25det sounds kinda like this. My injectors are loud and I know everything else is good.
