sr20det intake and exhaust gasket question

[240boosted]

Do you guy think it worth to spray copper spray on a new gasket for the intake gasket and the 7 layer gasket oem nissan exhaust manifold gasket

Nah no need.... it should seal. The 7 layer allows it to adapt to slightly non flat surface itself..... If the 7 layer doesn't seal, you got worse problems.

ok thank you i just seen alot people posting about that that applies for intake manifold gasket also too the oem nissan one seems a bit flimsy do you think that https://www.sikky.com/product/s13-sr...lnator-gasket/
this gasket would be a better seal or just try the gasket again i ask bc i had a vacuum leak and it would start from there thanks.

The intake is different from the 7 layer exhaust. 7 layer exhaust provides squish so there is some sealing help....

They apply sealant to intake cause that is 1 layer thin metal maybe?

Just a get a new intake gasket, don't need to apply anything. The intake gaskey sort of has a crush surface as well.... you will see when you get it....

intake spacer thermal gasket no spray its like plastic thats what you want if you can

exhaust you can spray copper gasket sticky, its okay for a new gasket and new surfaces i think its good. However it wont save you from leaks what you really need is the exhaust support properly attached to the transmission and the manifold properly supported etc....

Its water inlet and outlet. If you do not connect that water there is a wax element in the throttle body that wont expand so the idle speed will always be wrong. I know its dumb but it needs water to idle properly.
