Went to change my plugs and all but number two plug looks weird. Has like some orange crust on it. I was thinking maybe coolant leak? What do you guys think? The one on the right is what all the rest of the pkugs look like.

 

First, those are 2 different plugs. Was this done due to header clearance (shorter plug)?
Second, the gap on the one on the left looks closed enough that the crusty stuff could have shorted it out. Or did you drop or bump it while removing it?

 

The plug on the left looks like a V8 plug, doesn't really matter except as it goes through the head you start to loose some of the hex which could be problematic to get a socket o. Solid for removal.

The plug on left is gapped way to small and would not be firing cleanly, prob why theres a build up of crap.
