Blue spark plug wire????????

[dres240]

When I took the spark plug wire off coil of my 240sx,the wire looked blue inside where you plug the spark plug wire in at... The metal part looks like when a battery starts leakin or something... Like oxidation or blue rust or something. This is the first spark plug in the firing order so its the plug wire that is closest to you on the head of the block. WHat the heck is this blue crap and is it bad for my plug wire?

clean it maby with some brake cleaner, dont worry about it though

OK will do, but is this rust stuff going to affect performance? When i look at it, it reminds me of a crappy spark plug thats been overused and covered with carbon n oil lol

[navysnail]

you may just need new ones, they do wear out. it shouldnt affect performance to a noticable degree

My wires are Accel 8mm's that have been in the car for about 10,000 miles... Would that blue stuff mean that there is something wrong with the engine's first cylinder or is it just something i shouldnt worry about?

[navysnail]

no if there was somthing wrong with the cylinder the tip of the plug would be bad. i would say seriously dont worry about it, clean it out as good as you can, then stick it back on and forget about it

Cool, ya the car still seems like its running fine, it just surprised me today when i looked at it and it was all blue and whatnot. Thanks for the quick replies, later!

thats corrosion...maybe caused by moisture or if the silicon lubricant that came with the wires werent added... i would change it...it will eventually start acting funny... either clean it or change it...and by the way...stock wires are just as good as any other with the 240's ignition system...pretty strong at stock... so the difference probably wouldnt be noticable...i use 7mm felt the same as 8mm....
