engine noise

Well bless your heart, you sure are trying to get good video and audio......unlike a lot of other panty waste dumbasses on here. Good job.

I think I hear it......it does sound like a high pitched tick like valve train. That's what I would be concentrating on, I think. Tell you what you do. Get a long 3/8 extension. I used to have a 48" Snap On, until somebody liked it better than I did.

Take the extension socket end against the engine and place it in the area where you think you hear it best, on the valve cover, intake, head, wherever. Then stick the female end of the extension in your ear much as you can get it in there. This works like 10x better than a stethoscope and you will zoom in REAL quick on it.

Once you get the general area....which will probably be on a valve cover, remove that valve cover and start zeroing in more. Even stick it on each rocker arm bolt head. It will fit. THAT should really get you close.
