I'm in the middle of installing rockouts and I figured while I have the spark plugs out I would see what you guys think. I suck at reading plugs so any help is appreciated.

 

 

with the amount of detergent in gasoline now, and the proliferation of fuel injection, unless your spark plugs are to either extreme, oil fouled or breaking up from the heat, then you can't really 'read' your plugs.

 

This is the way to read them

or just keep guessing.

 

they look a bit on the lean side which can cause the blistering.

 

Back in the day, of points ignitions and carbs, the recommended way was to get it up to WOT, then cut the engine, and read the plugs. You were looking for an even tan color, if I recall correctly.

 

What do you mean by blistering?

 

The gap looks a bit wide. Have you checked it?

 

No I haven't checked it. These are the original plugs from 6 years ago. This is the first time they have been removed. I don't have a spark plug gap tool. I plan on replacing them anyway so when I do I will buy the tool and make sure they are gapped correctly.

 

You will get a lot of guesses on the net, everyone becomes a genius, whilst the real experts, will tell ya go get a wide band.
