Which silicone do I use to put on my coil packs to help the missfire on boost? There's a lot of different kinds, like the gasket stuff and the spray silicone, but can someone give me a picture or the name brand and which type of which one to use please? Also, is silicone the best thing to use, because I have seen posts about people using clean nail polish and heatwrap and stuff. I HAVE SEARCHED TOO!

Thanks,

Mike

Selleys 401 is the one i used. Its industrial grade high temp silicone, used as an insulator, amongst other things. You can get it at bunnings.

It's probably just as important to clean the contacts on your coils, where the spring sits.

The last thing i tried was stretching each spring about 8mm longer, to make a better connection with the spark plug. I havent had a misfire since, but then the weather hasnt been freezing cold, so it may be due to that.

no that wont work. that's more like a lubricant. get the 401. it's only $10.

Okay, the problem is that I live in USA and we don't have bunnings. Do you know of any other brands? Or any other stores I Can get it at? I don't think USA has shellys

it's used to seal glass on oven doors, and also used as an industrial electrical insulator.

not sure of an equivalent product, but there would be something.

here's the selleys 401. it's the only pic i could find

seal the whole underside of the coil, up to the bracket. leave the stem uncoated, as you need to fit the rubber boot over that. also make sure you clean those contacts. u can see mine are shiny gold. they were a dull grey when i started.

no worries man.

have you made sure your missfire isnt caused by your spark plugs? 0.8mm gap is highly recommended, although nissan specify 1.1mm

and many people have found the copper plugs to be better than the platinums/iridiums, that are also recommended.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
