Damaged Coilpack Electrodes

[sev]

The ends of my coilpacks are damaged, i.e the carbon ends on the end of the spring,

2 Questions,

1: Whats causes this?

2: Is there anywhere i can get replacements, as i dont really have the cash to buy a new set of coilpacks.

All coilpacks tested between 0.7 and 0.9

Its an rb20 gts4.

Thanks in advance.

sounds like the coilpacks were arcing? you should be able to get ends from a dead set of coil packs that nobody wants anymore

[sev]

Yeah that looks to be whats happened. I believe they are meant to have like a dome tip, but as mine have cracked away, they are far from it. I should really have got a picture. Im worried if i get new ones for somewhere, the same will happen again. Is there a problem elsewhere?

[StevenCJR31]

are they the original coils (how many ks on them?) or aftermarket?

[sev]

I've no idea how many k's are on them, however the car is on 120k's and they have been replaced at some point, as they have rb25 written on the side of them in paint pen.

Am i looking at general wear and tear, or have i got a problem?

Sounds like general wear and tear. I've seen them do this before.

But i dare say being rough with them, ie dropping them, ramming them onto the plug would cause cracking issues.

I doubt you'll have much luck finding new electrodes.

If they have RB25 written on in paint then they were second hand replacements. Did they still work? You need to be saving for a new set.

Hi Sev.

Those carbon tips are not used anymore on the new coils, They just have springs.

What you could do is clean the tips up on some sand paper and stretch the spring a bit, to make a good contact.

If that doesnt work i can send you a new set of spring ,(free) as i sell nissan RB coil packs and have some spares

Send me your address details if you need them.

Cheers,

Clive

I'll have a look at cleaning them up, it was a couple of weeks ago and i've slept since so i can't remember how bad they are, i just know they wont sit flush with the top of the spark plugs.

Thanks, I'll get back to you

Good, i just didnt want to hear it was this or that that needed replacing at $$$

Yeah thats what i thought, probably from a scrapyard or something, but yeah they all test ok.

Cheers for everyone's help

the coil ends of my coil packs are all burnt out and gone, running fine on 15psi gapped to 0.8 with no missfire / spluttering.

put in a spare set about a year ago with nice looking coils etc and car was missfiring and spluttering all over the place so just goes to show you cant just judge them on just how its looks

[sev]

I should gap down then, i'm at 1.1, but everywhere i've read since says go 0.8

[Dan_J]

gap them to 0.8 it wont hurt

main reason you gap to 0.8 is poor coil packs or if your running 15+ psi
