The "end All" On Rb25 Coilpack Failure Misfires?

I am somewhat new to skylines. previously i owned a gti vr6 which is notorious for coilpack failures due to super high underhood temps.

i never gave it much thought on the skyline until it started to misfire the other day. i started with the obvious and tightened all intercooler piping ect ect.

it had to have been the coilpacks at this point so before i went out and spent 600 bucks on splitfires i decided to take a look at what i was working with.

i pulled all 6 off individually and sprayed them with chem elect cleaner to get a better look. immediately upon looking at the epoxy they are made of, i thought "oh damn, its a single version of the VR6 coil" (the VR coil has all six prongs on one unit)

simple fix, cost me 3 dollars and i probably wont have to do it again.

JB WELD

jb weld, is good to 600 degrees C and is the same composition, albiet a bit stronger than the epoxy on the coils.

lightly coat the expoxy area on the coilpack that is cracked. let dry. i even used the fast setting kind, as i have used this on my VR with great results. is it ghetto? as i have always said "if you do a great job is hard to tell you have done anything at all"

i just did mine, and it runs like new. i didnt take any pics, but here is a picture of a VR6 coilpack with the JB weld on it for reference. hope this saves someone 597 bucks and a ton of headaches.

The problem is they are known for hair line cracks on the front of the coil pack not so much through the epoxy.

BTW blown intercooler pipes wont cause a misfire mate. Better start that apprenticeship lol

Not to mention they are 15 year old coil packs, with 15 year old windings. So a cheap fix isnt always a permanent fix. There are different reasons why coil packs fail and you can't assume they are all for the same reason. So no, its not the end all to coil pack failure.

so a crack in the epoxy, cant be fixed with jb weld? LOL

and when i say misfire, insert the word "sputter" when talking about loose piping. same sympton. bwaaahhhhh brrbrbrbbrrbrbrbrbrbrbr

worked great for me

Well the front of the coil pack isnt epoxt its plastic and all kinds of repairs have been trialed and none are permanent. There is a big different between over fuelling (blown IC pipe) and a missfire.

Well as long as it worked for you thats great ;)

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      After market rear camber arm adjustment

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
