Valve adjustment?

The valve cover gasket is a single piece, and as noted reusable...the rocker box gasket has all the wires your referring to...you should not need to disassemble the rocker box unless its leaking.

So do my valves need adjusted on my 2005 cummins? It keeps makin this knock time sound at random times puffs a little smoke and then it purrs like a kitten and i cant figure it out. It doesn do it goin down the highway and it doesn do it all the time. I put power service injector cleaner in it the other day and it boost the cetain levels and its been really hot didn think about that . Could that be my problem?
