I opened my hood this evening, and I noticed a blue spark coming from what I imagine is teh spark plug wire on the driver side of teh block.

what could it be?
whats a cheap way of fixing it?

 

If you have arcing to ground from a wire, it needs to be replaced. There is no cheap fix.

 

Im sorry, I do not follow.

I have a spark generating from one of the wires. It may be loose or broken. I havent been able to pinpoint it, because it was too dark.

I had the person that did my engine swap change my wires recently, and now this mess. Im afraid that it may cause an explosion of some nature

 

You have bad plug wires. get new ones.

 

i just changed them!!!!!

Could they be bad again? what could be causing them to go bad all the time? Ive had the engine in for 3 months! and this is the second set of wires!

 

okay...ill bite the bullet

 

hey dude, I have been having the same fricken problem. My msd coil glows, and summit replaced that three times for me, and right along with the 8.5 superconductors. I have had them replaced 3 times. But, my problem is the corona effect. it is a glowing coming from the boot to the plug hex. There is no pronounced arc, just the glowing. I am going to try some elitesparkplug.com wires, as one person on here had my problem and switched to them with no problems now. I will be going otvc wires.
hope this helps a little.

 

I had the same thing "corona effect" and also my msd was arching to the metal bracket. I changed the wires from taylor's to some otvc wires from elite and all my problems went away.

 

did the coil stop glowing to the metal bracket too with the new wires?

 

Glowing at the plug or a visible corona is not a problem and not abnormal. Arcing is a problem.

 

Arcing=meaning a spark jumping from the wire to the metal of the engine or frame (ground). Usually accompanied by a "snapping" noise.

 

yeah shoebox, sorry for the confusion... arcing is definately a bigger problem then my corona. Its just annoying though, cuz it idles kinda crappy and I can't help thinkin the corona is taking spark from the plug...

 

Your plug wire could not be on all the way, or it could have damaged it by it burning on the manifold. Other than that, no reason at all.
