Hello everyone,

I'm puzzled on identifying a new noise coming from my engine. I hear it around cylinder 4 and it sounds too fast in my opinion for a lifter. I'm thinking either a rod or main bearing but I don't want to jump to conclusions too soon. I've researched and listened to so many videos for the past week and still do not feel confident on deciding what it is. So this is where I'm asking for your help! It's a light noise and the only way I can imitate it is by rolling your "R" lightly. Other than that here's a video. Hopefully, it's easy to hear. I appreciate your time and help!
