Rattle in driver said head, loose rocker, valve, lifter???

[Jmoore1225]

Motor has about 10k miles on it, was driving Saturday night & suddenly a loud rattle comes about. It is in drivers side head/valve cover? What commonly goes wrong in there? Rattle goes up & down w/ Rpms. Thinking its a loose rocker, wanted to get everyone else's thoughts.

What needs to come off to get drivers side valve cover off? Please don't say turbos!

Truck has a set of torque tows, studs, 4inch turbo back, CAI & just running Gearhead street.

The crossover pipe has to come off then you got full access to the valve cover. Takes about 30mins to get to the valve cover.

You should probably check the rockers first...before we just randomly start guessing
