They are rubber seals, you shouldn't need any sealant.

Are you sure it flat on the head surface, no wires jambed under there at all, holding it up?

[ZILR-34]

yea there the rubber seals one. i toke it off today again and i clean the surface of the head and the rocket cover. ill see how it goes tomorrow when i take it for a drive.

Did you change the rubber washers?

And the screws are not very tight only a couple on nm. Did you do them up tight?

[blind_elk]

They're rocker covers.

Yeah, make sure you haven't caught any wires and such between the cover and the head. Do you know exactly where it's leaking the oil?

[wrxhoon]

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

[ToF]

Mine isn't pissing out oil but still leaks a little after each drive, both from the back of the rocker cover and the bottom of the half moons. Anyone know how much a workshop would charge for this job. (Just cbf with it anymore )

<{POST_SNAPBACK}>

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

Yes, you can get them from Nissan. And the dealer will know the part number - just ask for the "D"s. Little smear of Silastic as you assemble them into their location in the head.

[wrxhoon]

Yor local Nissan dealer will have them, they are very cheap . I usualy put some sealant where they mate with cil head case.

Curious to know where this comes from:

rocket covers

<{POST_SNAPBACK}>

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 ?

<{POST_SNAPBACK}>

[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......

[xr8eater]

cork gaskets are still used in many applications

and i agree with steve you need sealant on the half moons as nissan states in the manual

[wrxhoon]

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 .

[xr8eater]

lol very quick eh holden

[Bobjones]

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.
