Changing Rocker Gasket

[Weyro]

Just wondering if you need to use any silicone sealant when replacing the rocker gasket?

Cheers

No, make sure both surfaces are very clean and just use a bit of multi purpose grease on the seal so it's air tight.

Just in the corners where the cam caps meet the head just put a small line across the seam and the same for the one for the distributor clamp.

This is wrong the Toyota manual states to do the above. because the seal does not squash into the tight corners good enough to make a good seal.

Cool, thats what i was thinking

In my many years of working on these cars I have never ever used gasket sealer on the cam cover gasket. Just a touch of grease has always done the job perfectly for me.

They use a grey silicone from the factory, I have the part number for it at home it's in the manual I got from Toyota 15 years ago ya could say I have been building these engines some time too.

ive never used sealant or grease :/

when you remove it (if it hasnt been removed before that is) you`ll see the grey sealant...round the timing belt area especially just reapply it after and your good to go

is it leaking? if its still soft you dont have to replace it

[TrisK]

Moral of the story is you have to use sealant

but the offical line, from Toyota, is you should.

So if your doing it and dont have any, dont worry

if you have some, its not going to hurt

as rob said... a new gasket wont leak straight away but after a few runs it "will" from those areas he mentioned.. better of doing it right the first time

[ryan lang]

mines still fine :/ no sealant

[Weyro]

Mine was leaking quite alot a while ago, so i took it off cleaned the gasket and the joining surfaces, then put a shit load of sealant on the cap cover things. It was fine for a few months but now its leaking again, think i might have used too much sealant.

i use a small bit of silicone sealant aswell

[micky boy]

I always wonderd why i had gray silicon sealer near my cam ect when i've took the old rocker cover gasket off!

Thanks for that Rob i've never used sealer my self and never had a problem but i might start useing it lol

I all ways use a little bit of loctite premium silicon just on the corners of the camshaft caps and a bit around the distributor and its allways been fine
