coil pack cracks

[Mischief7m]

i was told i could repair the hairline cracks in my coils using clear nail polish, is this true?

if so, is it a perminant fix, or just to give me a few more months outta them.

as it is right now, my engine breaks up bad, but only under full load at around 6500rpm

thanks in advance for any input

yeah use some nail polish, Then get some Heat shrink that will fit around them and a heat gun. Thats a pretty permanent fix there, as long as the coils are still good.

nail polish only buys you some time..........i pulled my coil packs out, and the nail polish was all burned off, pretty cool actually.

i tried epoxy, but it didn't stick. then i read the back, and it said "does not work on polyethylene and polypropylene plastics".......so try to avoid those kinds.

yea, im using the ngk's gapped to either .032 or .028 i dont remember which.

but i need to pull them to atleast clean them, because my car has been running rich on them for quite a while now.

should i coat the whole coil in it, or just where there are cracks?

just the cracks, i had chunks taken out on one of the engines but i just rebuilt the wall with the jbweld and it still works fine

i would scuff the area of the crack with heavy sandpaper to help it bond
