You need to replace your valve cover gasket. Oil from around your camshafts is seeping down into the spark plug area through a tear or separation in the gasket.

From what I've read, a bad VCT solenoid can also leak oil. That's the module to the left of your spark plug wires when you remove the black plastic "Powered by SVT" cover from the valve cover. I believe you would be able to see a trail of oil leading back to the VCT module if this is the case.

Question, my SVT has forced induction(Pwsc), I have Taylor wires and Azfs22c copper plugs, my ? is what should my plug gap be at, currently .60 is thatr ok for a supercharger?

[WD40]

.060 is what you really mean.

Regardless, that is generally way too big of a gap for forced induction and will cause missfire issues.
.035-.040 is a more typical FI gap.
(You can find further info on what gap to use in the Forced Induction Chat forums)

Thanks WD-40 I've been unsure about that for a while, when I nchanged plugs I mistakely followed the guy that owned it before when it came to the gap, two plugs were at .060 and two were at .055. It does like to stumble when I rev the motor and the rpms drop down it will go down below idle speed about 150 rpms, stumbles almost stalling out then picks up to a normal idle, is that result of the plugs being gapped wrong or something else? Thanks for the info.

[WD40]

^^^Not sure about the idle symptom.
But, I do know that .055-.060 is too large a gap for FI.
(Again, I'd check on those forums for the exact gap to go with)
This is the NA (Naturally Aspirated) section.

the 411 on spark plugs: http://www.motorsport-developments.c...AF272_tech.pdf Iridium is preferable because the thinner center electrode diameter allows for a higher quality spark and because iridium degrades much slower than copper it allows you to run a larger gap (or just replace your coppers constantly). Also the AZFS22C is the proper heat range for a regular Zetec but I don't think it is the proper heat range for a SVT. http://sparkplugs.com/results_app.as...1&AAIA=1385580 also helps out a lot for the specs for different plugs and they have some of the best customer support I have ever worked with.

so i bought some champion plugs they are the closest ones to stock i could find (all that advanced auto had)and i cant remember the size of the gap on the stock plugs but these champion ones i bought are .001 either larger or smaller is this going to make a difference?

Always measure pregapped plugs. They get tossed around a bit before customers get their hands on them.

Can I use CFM, or Taylor wires on my MSD coil?

i just installed copper plugs and taylor wires this week and it is GREAT. i have not gapped the plugs and probably wont because im lazy and the closest auto store is about 20 mins from me. anyway, i paid 8 shipped for my motorcraft coppers, DO NOT buy them from cfm or fswerks or even a ford dealer, just look on amazon and ebay. they are simple plugs you cant go wrong on those sites. i just paid like 60 bucks for the best tune up. plus the taylor wires look sweet and match my car! :)
