making some valve train noise was wondering if it’s normal

it’s a 2003 silverado with a 5.3 still has the same power but started making this noise?

I have my silverado 2003 With electric fans and subs is this the voltage regulator in the alternator failing or what could this be?

could someone please help me i re did the wires and it still didn’t fix it the transmison still feels like it’s in protect is there something i have to do to fix it specifically it won’t downshift to first to anymore or use first at all it feels like it’s trapped in 2nd please someone with more mechanic knowledge help me out

On my 2003 silverado My power steering seems to have this problem where when it’s on a cold start it’ll work fine and turn fine but after about 5 minutes of driving the power steering gets real stiff almost as if it got hot and it won’t turn as easy and makes a clicking noise when i try to turn without my foot on the gas the cooler behind the grill is rusted out i don’t know if i need to replace it

I just swapped a 5.3 into my cateye it has long tube headers new lifters A big Cold air intake a fresh rebuilt 4l60e with a shift kit and corvette servo it’s pretty quick compared to the v6 that was in it before what else could i do to wake up my 5.3 And make it quicker the 5.3 came out of a 2003 crew cab and is the lm7 it has traction bars and 4.10 gears with a gernade g80 I was thinking if i get a real posi unit will that help with acceleration?
