09 gt with 46,000 miles.. decided to change the spark plugs, and didnt really like what i saw. the plugs seem oily in my opinion.. what do you guys think?

Check your ol level?

Do you have a catch can?

Check your throttle body for oil residue.

1. oil level is good
2. dont have a cetch can
3. i will check tomorrow.

does the oil on these plugs scare you? the car is running really strong.

i would start with pressure test.

I had the same thing with my car last year, but it was the valve cover gasket leaking oil to the plugs,,,from what i see in your pictures the plugs are clean on the tip there is no oil there, so it might be a leaky gasket...i could be wrong.

I'm with toorbeenee. Looks like valve cover gaskets.

 

[whitestang41791]

How would I make sure it's definetly the valve cover gasket? Or do I just replace them?

The car is running way too good for it to be the rings

For comparison these are from my 2010 with 6,300 miles. No oil consumption issues and a fairly clean throttle body and engine runs great. I'm not going to worry about mine.

I wouldn't think your valve covers leak, the nut of the plug would be oily also.

Do you have a tune?
Could be running 'rich'
No enough fuel being burnt and creating 'gunk'
Either way that plung should not be that gunky, maybe try sea foam and change fueling station.

UPR catch can if ur gonna get one.

Don't know if your asking me or the OP, mine was stock tune. I am installing a catch can with the Paxton kit.

I have a bama tune for 93 octane, and I only use Sunoco gas. Seem people have suggested its the valve cover gasket, as others are saying ford uses oil from the factory when installing the plugs, guess ill wait a little bit and pull a new plug

 

[Roadracer350]

The tips look fine. I bet its either the VC gasket or the stupid system for the oil breathers plumed into the manifold. Take your CAI inlet off the throttle body and open the butterfly's and see if theirs a lot of oil in the throttle body.

 

[whitestang41791]

throttle body had a little back residue but no oil

 

[05stroker]

That would make sense.

 

[wallace]

Like someone said, it's most likely 'oil' being "plumed" into the manifold.
I'm willing to bet car w/ oil separator don't have gunky plugs. I don't!
Here's a good link about plug condition.

is it oil or is it just carbon and gas mixed? alot of times if you are just starting the car to pull it in position to work on it, the gas wont burn right off and you will be left with gas on the plugs....i wouldnt be concerned, just change the plugs and move on with your life.....go to chuck-e-chees's or something!
