I've noticed this noise for a week so far and have only driven my car when needed I checked the oil and it seems a little low I plan to change it soon after I replace my valve cover gaskets, but I just wanted to see if this could be the fuel dampener.

 

Welcome, but that vid gets shaky just as the RPM drops. How many miles are on your Z and what does oil pressure look like between 1200-3000 RPM?

 

sorry for the late reply I went to work the evening,My Z has 150,800 miles on it. Right now my oil pressure gauge does not work I plan on putting a new one on when I change my oil.

 

Not sure if you figured it out yet, but the gauges, they're all one piece. Can't change one without changing them all
