:headscratch:Ok, I tried tightening down the rocker arms on my 302, because there was a clicking noise coming from them, so I tightened them down and the clicking noise went away. After driving it for about 5 minutes the same noise came back!!! There was one rocker arm in particular that was very loose, and when I went to tight the nut, it wouldn't go down any further and the rocker arm was still loose. The motor is a 302 with solid cam and everything is stock. Please help if anyone has been though this!
