Okay so I am hearing this weird ticking/staticy sound coming from the timing chain cover area near the front valve cover. It is a very light sound and can not be heard inside the car UNTIL I get up to around 55mph at that point I can hear the sound in the cabin. IMHO when you can hear it in the cabin it sounds like a static coming from the audio but Ive ruled out audio since it can only be heard over 50pmh in the cabin.

Anybody have any ideas? Ive searched and read a few things such as timing chain tensioner, TC guides, possible bad gas (just filled up with 93 at a different place, so I will know within a few days if thats the problem)

Thanks peeps

Also the sound has no rhythm when it can be heard in the cabin. I cant tell under the hood as it is fairly faint

Get a mechanics stethoscope, they really are great diagnostic tools. You'll be able to pinpoint where in the timing cover the noise is coming from and be able to eliminate a lot of things because of it.

I think it was just TC rattle. It went away. My buddy is still going to look at it
