Im having a random ticking noise coming from under the hood of my 09 fit and cant figure it out

It’s hard to say but it’s something related to a single cylinder. I woulda said loose spark plug but it actually sounds like air. If you actually open the hood it would be easier to tell. Maybe exhaust leak?

 

ill try and get better video under the hood tonight. I got another one im uploading from this morning where it gets worse with more rpm. I originally thought it was a injector but it literally sounds like someone is wiggling a rocker up and down

 

Get yourself a stethoscope from harbor freight and check valve cover/timing cover. Not something I'd roll around with for too long... Good luck.

 

I got a better video this morning. The noise sounds like its coming from the injectors. I know the fuel pump is going bad because you have to turn the key on for a few seconds before starting to let it prime.

 

Have you checked spark plug torque? A loose spark plug is pretty loud and sounds like someone knocking two pebbles together.

when I found a loose #4 cylinder plug, I literally spun the plug with my fingers for like 10 turns before it seated. It was literally that loose. Literally held in by the coil.

*edit: I just remember that accessing plugs is a bitch on the GE8. I have a GD3 and you don’t need to remove the wiper cowl to check the plugs. I would still try and check that, it sounds like it could be the culprit. It sounds in time with the firing of one cylinder so it could be valve lash or a plug.
