If your spark plugs or spark plug wires are bad, would it make a tapping noise. Something that sounds like it needs a valve adjustment?

 

normally faulty wires and plugs will cause a misfire and some arcing...as for the noise i would recommend a valve adjustment as you questioned in your post

 

valve job was done, and still some tapping

 

not to steel from your thread... but when you did your valve adjustment, (not to sound like a ricer) did you notice a power gain? i really need to get one done...

lol.

it just make car run smooth like new. should be checked every 40-50k miles. not really sure about mileage

 

no, didn't notice HP gain, just got rid of the annoying tapping sound though. I can't notice any power because right now it's untuned.

 

^ gotcha, thanks

 

If you have a bad wire it will make a ticking sound as it arc's off whatever it's grounding to. Like others said, it will run very rough as well. At night it will look like Star Wars under your hood if that was the case

Aftermarket header's will also create a louder "ticking" sound from the motor which is normal.

 

where would the light show come from though?

from wherever the wires are arching if that's the problem.
