Valvetrain Question Okay, I've got some angry clicking sounds coming from underneath my pass side valve cover and my MPG has taken a dump (both happened a day or two ago). I'm 99% sure it's not an exhaust leak, so my question is this:
If I bent a pushrod, cracked a spring, or killed a rocker arm, can I replace the individual component, or is it a better idea to replace the set? For example, if it's a pushrod, would I be better off with a new set, or would one replacement suffice?
This is a DD with a catback and a lid. I do some spirited driving, but nothing crazy

Remove ALL the pushrods and check them for straightness. If and when you find a bent pushrod inspect the spring and rocker associated with that pushrod. I would replace the rocker associated with any bent pushrod.
Inspect all of the springs for cracks. If you find a broken spring(s), inspect the rocker and pushrod associated with that spring. I would replace the rocker associated with the broken spring and check the pushrod associated with that spring for straightness. You'll also probably want to do a leak down test to see if the valve is still sealing. While you are at it, you can do the test for all cylinders.
Good luck.
