Like it say's, I wanna gain some knowledge in this area so does anyone know of a site that explains and shows pics of what spark plugs look while running rich or lean? Like for instance how it should look around the tip and what not!
Thank's for help!

 

check out this site by NGK for a sweet *** write up on spark plugs, preigition and detenotation.......

Thank's that's a good site, but does anyone know of a site where they have pictures of the plugs and the definition of the colors?

 

in my experience, only thing that changes the actual color of a plug is the use of fuel additives. other than that, black everywhere is too rich and white is clean/lean. excessively lean (pinging) plugs will show damage and be whiter than a good plug.

its a good idea to look at plugs from a stock, well maintained, honda as a reference when you do stuff like turbo.

 

A happy plug should be grey in color. Black (if it's carbon) is excessivly rich or if it's oily black you have a problem burning oil. White plugs mean your runing lean, detonation will show on the plug as little tiny specks on the plug (pieces of the engine)....sorry i have no pics but figure between white and black is good.oh and the tip will probably be a lighter color due to it being the point of ignition

 

What if the plug is brown, although clean, no specks??

 

brown is good
no specs is even better

when it looks like someone hammerd on your sprak plug with a bat for hours is when you have some engine issues that need to be attended to

I like your analogy ...luckly i haven't pulled any plugs like that.....

 

So brown is good........anyone else?

I pulled my plugs the other day and the electrod was a grey color and I had white spots all over my plugs. Am I running lean or detonating?
