Hello. I am hoping I can find some help here. When removing the valve cover there is a piece of round plastic like a cup that came loose from the rear of the exhaust cam shaft on the passenger side on our 2015 JKU. I was going in to replace some noisy rocker arms which is done now but this cap keep falling off when I try to put the valve cover back on. Is this piece necessary? Below is a stock photo. The left side shows the plastic part I am mentioning.
I tried adding some adhesive in the hopes it stays on but I am curious if it will do fine without it or do I need to replace the cam now?
