Curious to know where this comes from:

rocket covers

As has been pointed out, it is actually rocker cover (probably more correctly 'cam cover' in this case as there arn't any actual rockers).

Anyway, only the rear 'half moon' seals require some sealant at installation. The rocker cover gasket requires none - just make sure it is 'square' in the groove of the rocker cover (no twists, etc).

It comes from the old cars that use to have rockers .

You dont need any sealant on the rubber that goes in the groove , they never leak , most times you can even reuse them and they dont leak if installed correct.

If you think they are hard to seal, how would you go with old cork gaskets ?

'rocker' does, 'rocket' doesn't AFAIC (and I've been around 'a while')

If your saying the half-moon seals don't require sealant I disagree.....and so does Nissan. OTOH, the rocker cover gaskets themselves don't need any sealant

If you think they are hard to seal, how would you go with old cork gaskets ?

[sigh] I don't think the are hard to seal at all. As for cork.....come back and talk to me when you've worked on a veteran car......

steveL ,

I meant you dont need sealant on the rubber gasket but as i said earlier i use some on the half moons where they mate with the cil head case .

I have worked on some old cars in my time, i have been around for a while and i owned a very quick EH Holden many moons ago .

I had a quick VK...whats ya point...

And yes I agree with the above, re the sealant only on the half moons, use that orange stuff (name evades me at this moment).

Also when tightening the covers bolts/screws to them in a similar fashion as you would putting a head on, that is night tighten them around in a circle, and fully tighten first go, this will ensure that the mating surfaces are meeting square!!!

Just replaced the right cam cover gasket, the rubber washers and the 'D' seal for the first time and all I used was $10 silastic from Autobarn only on the top and bottom of the 'D' seal and tightened the screws till the washers started to 'balloon' slightly. Been 4 weeks and so far so good.

      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).
