I removed my 12 year old aftermarket Magnacor wires for NGK blues. Now I'm hearing the engine making knocking sounds. What is it my valves? How did that come to be?

I have V-power NGK plugs by the way.

 

Most likely just a coincidence and not actually caused by the new plug wires. Put the old ones back on to be sure, though.

Also, verify that you have the wires in the correct order on the distributor cap. If not, the engine will run very poorly (happened to me once).

Otherwise, the engine may need a valve lash adjustment, or a worse possibility is that one or more lost motion assemblies has gone bad.

 

Yeah I don't think my new wires are the problem cause I put back the old wires and there still making the noises.

Do you mean valve adjustment? Is there a how-to procedure anywhere?

 

http://www.c-speedracing.com/howto.php has a good write-up.

Are you sure you have the wires installed in the correct order on the distributor cap? How loud/bad do the noises sound? Like just a slight ticking sound or a loud knocking sound?

 

I'd say you can't hear it in the car. Only when you pop the hood and your just standing in front of the engine, you can hear the noise. If you have a desk in front of you, use your knuckles and tap the desk repeatedly. Thats what it sounds like.

 

take a sound vid and post it up here.
