Oil on spark plug

Changed the spark plugs in my 97 gt and noticed oil on the #7 spark plug. I'm not to familiar with these engines seeing as I just bought the car. Any suggestions on where the oil may be coming from.

Since when is oil ok on a spark plug? Imo oil in a spark plug is not a normal thing. Maybe the valve cover is leaking or maybe you have blow by in the cylinders. Oil on a spark plug doesnt mean the end of the world. However you may want to find the cause for it and repair it. Just my 2¢

I'm gonna say the oil is coming from the engine but that just my educated guess 😋 now on a more serious note it could be your valve seals or piston rings more un likely is a head gasket

I'm not brilliant I just know basic automotive tech. Common knowledge is that oil in your combustion chambers is a very bad thing. Whoever told you that is an idiot.

[QUOTE="PBrown92;1807897"]How do you perform a leak down test?[/QUOTE

You have to get a tool and you take all of your spark plugs out and take a fuse of for the fuel pump. You screw in a gauge to the cylinders and they should all have about the same pressure i think i haven't do it in a while i know harbor freight sells the tool. Im sure you can find it on youtube

@ mustangman705 white sludge build up in the engine is not a fatal blow nor does it mean your getting coolant in your engine! It simply means you are doing short trips and the engine isn't getting up to temperature so condensation builds up on the surface of the inside of your engine like the inside of the valve covers and oil cap. It can be resolved by repeatedly running your engine at operating temperature . You should also change the oil after doing the full temperature cycles because the water and oil mix will create a highly caustic acid in your crankcase which can etch bearings, deteriorate your gaskets and wear your block. just figured I'd let ya know

I said to replace the valve stem seals in the cylinder head , and someone replied that valve stem seals are on the tires and have nothing to do with spark plugs

Maybe i've never heard it called a valve stem seal. Still doesn't make sense to me.

Thanks for the assumption though.
