Replacing Rocker Cover Gasket

[ToF]

Hey guys,

Tomorrow I'll be replacing my rocker cover gaskets and the semi-circle rubber seals at the back. I just have a few questions:

1. Is there any special method of cleaning the surfaces before putting on the new gaskets?

2. What sort of adhesive do I need to put on the semi-circle rubber seals and where can I get it?

EDIT: 3. Should I replace the grommets on the screws that hold the rocker cover down? I don't think Nissan even list them in FAST, all I could find was the washer for the screw but no picture or mention of grommet in FAST.

Thanks everyone.

OK I found most of my answers in this thread http://www.skylinesaustralia.com/forums/in...showtopic=71313 by searching indirectly. Sorry about that.

Anyway I'm still not sure if nissan can get those rubber grommets for the screws, anyone done this before and got them?

1. either use degreaser to completely clean the rocker covers or wax/grease remover (or even just petrol) to clean the 'grooves'.

2. 3 Bond is probably best sealer and it's what the factory uses. Burson's carry it.

3. the little rubber washers are available from Nissan (and shown in FAST). Pesronally I would replace them at the same time as they compress and go hard with age.

Thanks for that reply. Still not sure about the rubber grommets/washers because in FAST they appear to be a thin metal normal washer, it looks nothing like the rubber grommets that I have on my screws now. :S

There should be a thread with info on how to get it and how to install it but I've already forgotten where it is, sorry.

Umm, after I did the job it now leaks oil.... more than before :S

I think I may have tighened the screws too hard, what can I do from here?

[ToF]

Oh shit, I just read the post from 3lit3 32 again...

"I would also recommend getting new rocker cover bolt rubbers as this will help the screws all pull down evenly. They have a flat side underneath that stops when the thread runs out, if the seal is squashed, it won't hold the cover down properly."

Does this mean I should undo the screws until the washers are in original standing state (not squished)???

[ToF]

No one????

It seems the new gasket is still in good condition but is leaking near the back (towards the firewall) and on the sides which are facing down more respectively for each rocker cover.

[SteveL]

Suggest you re-check the seating of the new gasket. Tighten it down evenly in a criss-cross pattern.

The part number for the washers under each rocker cover bolt is:

13268-58S01

Yer I've followed the manuals sequence for the screws. I'm going to buy new washers now and try again.

ah this can be done over and over again and it will still leak. The best way is to use a gasket sealer all the way around. Then start screwing down the screws from the middle and working towards the back of the engine make sure your engine is stone cold when doing this some loctite thread locker may help.

[ToF]

So anyone suggest I follow xr8eater's idea of using gasket sealer?

And did you mean to use the gasket sealer after I mount the rocker cover down and screw it in, like to seal the outside???

So anyone suggest I follow xr8eater's idea of using gasket sealer?

I don't....put new gaskets on my RB26 without sealer (apart from factory recommended areas) and haven't had a problem.

the factory uses gasket sealer on the head but go ahead and dont use it just give it two weeks and it will be leaking again up to you dude. I did mine they leaked and then i used sealer never leaked since
