Ever since i bought this truck, its always had a little ticking to it...Not anymore.
Now it clacks, and loud too! Sounds like on single cylinder's exhaust valve. I say that because you can hear it ringing all the way from the primary tubes to the tail pipes. I'm going to pull the valve covers tommorow night to see whats going on. Hopefully nothing is broken or bent. I'm afraid of what i may find. Oh yeah, i recently installed my 1.75:1 rockers for the second time. Hopefully one of them is the problem and nothing catastrophic has occured.

i also will be driving it to work tommorow morning. call me crazy but i just drove 2 hrs form huntsville up here. no power but otherwise running fine.
