just wondering do u cover the hole lot? or just the steam of it?
I have read the previous replys and and not sure where exactly you are putting the epoxy glue on the pack.

If you look at my 4th post, I have posted pictures of where to put it.... doesn't get any easier

You guys are confused about the whole silicon thing.

What you want to do is spray the coils liberally with silicon spray

It's an aerosol lubricant, looks & feels like oil, repels moisture superbly - not a curing sealant.

I had an arcing coil issue some time back, now whenever I change the plugs I spray the coils liberally and hey presto no more probs. If you're hellbent on a more permanent fix, why not tape them up with (are u ready for this) self amalgamating butyl tape. Goes on like leccy tape, then heat with your paint stripping gun etc, et voila fuses together and shrinks around the coil insulating and waterproofing it.

When I was contracting for Sydney Water we used this stuff on external electrical connectors on sensitive datalogging equipment that was mounted inside sewers - not an electronics friendly environment. High temps, lethal caustic gases and flooding are the norm.

Should be able to get this stuff from Electrical wholesalers, Blackwoods etc.

Yeah, but I would be inclined to coat the inside with the goo that Telstra use for cable jointing to repel moisture. I don't know it's proper name - but it's clear & has the texture of grease. I reckon leccy wholesalers would have it.

Just thought I would update this thread with some more info....

Although my coils were covered in araldyte, they started playing up again on the weekend, so I pulled them out including spark plugs to see what was going on....

Well first of all, my tuner gapped my spark plugs like so:

1:0.6mm, 2:0.7mm, 3:0.7mm 4:0.75mm, 5:0.6mm, 6:0.6mm

not to mention a whole bunch of bolts missing all over the place, but anyhow, once they were re-gapped I turned to the coils.

Upon inspection the araldyte looked fine. No cracks, no chips.

So I took the rubber boots off, and the little springs inside the shaft and notice the shafts were a little corroded (that blue/green crap you get on your battery terminals). So I sprayed the shafts with WD40, and cleaned them out with steel wool. The car runs better than it ever has now, and is very smooth.

So also take this into consideration when looking at your coils.

You've raised a good point, Zahos.

moisture seems to play more in the faulty coil/misfire scenario than many of us had previously thought. I revived one dead coil and brought two DOA's back to life with silicon spray, and noticed the same corrosion @ the spring terminal. I still reckon heaps of gooduns get tossed, where the real culprit is condensation.

    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
    • On the bright side, the weather will turn much nicer for working outside shortly....sounds like you might need to start on a neighbour's garden next
