spark plug condition

i posted a thread a while ago about my ignition components, turns out that everything checked out fine....someone had mentioned that i might have bad plugs, i am somewhat of a newb to all of this so i attached some images of the plugs for some more experienced tuners to take a look at...hopefully it gives enough information.

Eh, I wouldn't put those back in.

Go ahead and order 4 new plugs...one thing to cross off the list of bad things.

yeah, the center electrode looks pretty rounded. There should be nice sharp looking edges

I assume the trailings are on the left side?

The plugs look like they are running pretty rich.
Or, are you using some kinda funky additive?
You should be able to see the white insulator under the center electrode, and I don't see it.

I pulled mine out today mine had a white/yellow powder on them, i'm assuming this is coolant? Also my Leading and Trailing plugs were switched, stupid last owner! what happens when they are switched like that? I can post pictures later if needed.

Sorry to threadjack, acsantaclara.

Those tan deposits (you can see a little bit of it on the left-most spark plug above) are normal.
Those are typically left by gasoline additives.

If it were burning coolant, the spark plugs would look really CLEAN.

Swapping the leadings and trailings really doesn't do too much.

i never recommend cleaning plugs unless they only have a few thousand miles on them.

the plugs on the left have a wetness inside which i would either assume is oil, coolant or gasoline, only someone experienced can really tell what is on them.

that plug is fine, just throw it back in the easy-bake oven for about 10 more minutes and you'll be good to go.

Haha whats funny is the engine is still running good, I just have a water seal leak. Exaust going into water not water into engine. Anyways, I have like 5 pictures of each spark plug that was in there and this 1 isnt the worst. any chance these might be the stock spark plugs? haha

Wonder if it will run any better w/ new sparks.

But my easy back oven takes SO LONG, just 1 backfire and I get a couple dozen brownies. I hope to upgrade to dual exaust, less restriction on the brownies, should double the output. At least 10 to 15 more B/s.
