Thumbs up New found power!!!!

Runs smoother, and no more spark knock! I finally got around to changing the plugs in my Dodge. It's been spark knocking for some time now... shame on me

The one on the left is a properly gapped plug at .040" (an old one I took out and re-gapped). The one on the right is about the average of what I took out (I didn't touch this plug, it came out that way), about .070" or so.


What causes this???

Looks to me like someone had too many polish pops when they decided to go out and put new plugs in the motor!!

If the engine is a 5.2 or 5.9 and even the v-6's the will blow the intake plenuim gasket and carbon up the motor and spark knock. (Internal vaccum leak) We fix alot of them at the dealership.

the electrode was eaten up by the knocking cylinder causing the increase in gap. Other than being worn out they don't look bad. .060 is not an uncomon gap for a late model car or truck. What attributes to it also is that cylinder running a little hot causes the ground to get soft and sink. Not uncommon at all
