If its at the rear its probably comimg from the 1/2 moons , did you change them ?

the oil was leaking from the back. where can i get the half moon rubber seals from? would they sell them at nissan? if so anyone know the Serial number for that part?

cheers

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

[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!!!

  • 6 months later...

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.

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
