I tried searching the other threads but only found information on #3 cylinder. I only had enough time to pull half the plugs but if I have the order correct, this is from cylinder 8. So out of the 4 this was the only one that looked like this. Shoot me straight fellas.. kinda screwed or all the way screwed? Lol
I’m the guy who bought that 04 Cobra without inspecting the car first.

Electrodes look good. Probably just had the engine bay washed and there was a little water in the plugs holes on the plugs that boiled off. Just change and run it for awhile and check again.
Just my initial thoughts. We’ll see what the experts say.
Water got in by the gasket on the coil cover. Plugs looks great. You are fine.
Ok.. this side of the motor is missing the coil covers.. it looks like someone broke it off. I have to drill out the snapped off bolt and use an easy out to get em outta there. But 10-4. Thank you!
Easy fix. Post some pictures of the car!!!
No issues... replace plugs, blow out plug holes to ensure no water or debris.
Run it
Run it
I’m out running errands with the wife.. i’ll post them to your comment when I get back to the house.
It looked to me like the spark plug donut gasket was bad, and that was caked on oil.
Looks like they were running boostane or something based on the reddish tint.

Stick something down that #8 plug hole and see if you find any oil
Decent looking Cobra, Will. Hoping things will turn around for you very soon. What looked to be a possible issue is now looking like a more mild fix.
Thank you! I’ll take the win however big or small. Ok, now I’ll stop making threads for every little thing I find wrong on the car now lol.
Agreed that looks like moisture getting in #8 plug hole. Not uncommon. The brown stain could be oil coming down from the donut gasket though, or it could be rust. Shine a light in there and look for oil at the bottom where the threads start in the head. Usually oil will make its way all the way down the threads of the plug. Not seeing evidence of that from the pic though. The fix for that is obvious...
For the moisture fix, the best way to prevent it from happening is a dab of Rtv where the harness starts to go under the coil cover. Should never leak again. Good looking car. Need to bring that ass down though! Jmo

What it looks like was just some water may have gotten in there. The spark plug well actually looked extremely clean and I couldn’t find any oil or signs of leaking. I bought some easy outs yesterday so I can drill the sheard bolts for the coil cover so maybe that’ll help keep water out once I put a new cover on that side. When the car got delivered to my house it was like a tsunami out and pouring down rain. That might be where that water came from now that I think about it. And I agree about the rear. The previous owner built this car for the strip so I’m almost certain he had some big ass tires on the back. It has viking coilovers in the rear so I’m hoping I can just adjust them and level this thing out. My knowledge about cars, specifically Mustangs is pretty nonexistent so I’m trying to do my best to learn as much as I can about these cars. Thanks for your reply.
