Oil on spark plug threads

ImportEater98 · Mar 16, 2004

I have a 98 GT with nitrous. I change my plugs every 3 bottles....and whenever i pull them out the electrodes look fine...no detenation...no nothing.....but this past weekend i pulled out number #7 (i think, its the driver's side rear plug) and the electrode tip was dry but the threads were SATURATED in oil (maybe mixed with a bit of fuel...judging by the smell), is this a cracked head? or maybe just something stupid? The car is running absolutely fine with no smoke or missing....HELP

You might have cracked your intake a little. Those stock 96-98 intakes sucks and nitrous doesn't help them either.

Thanks for the response...though it wasn't the one i wanted to hear Well i'll run it till it poses an further problem, i guess...Anyone else have this problem, or think of any other possibilities? Thanks again.

No oil journals in the intake, just coolant. have you done an oil change lately? Spill any oil? Maybe a leaking valve cover gasket or PVC valve. Check that out first. I wouldn't sweat it too bad. If you really want you could try to do a compression test on that cylinder.

Thanks for the info guys.....i guess i won't sweat it untill she blows! Put the first bottle through her this weekend.....and she eats it like a fat kid in a candy store!

Oh and JL, nitrous......speed thats cheap......went from a 14.6 @ 96mph to 13.3 @ 108mph (best time)...with a drag suspension set up, and minor bolt ons.....real good time....especially purging it at a red light next to a car that has more stickers than rwhp! lol Thanks again guys.
