I know everyone is having this issue and it appears I am as well. Where is the cheapest place to buy the rockers lifters gaskets ad everything to do the job. I can buy the gasket local and the lifter but I can't find anyone who has the rocker for sale? Your help would be great thanks.

 

What engine? What year? What issue specifically that everyone is having?

 

I have a loose Rocker Arm 2002 4.7. Knock sound coming from passenger side valve cover I used a Auto stethoscope to pinpoint the area of the knock. I have not removed the valve cover yet because I can't find a place to purchase the rocker arm from. I don't believe mine has dropped the arm since I'm not having any misfire codes.
