a friend and i have been in the process of removing a del'orto carb and intake manifold from my 13b 6 port (datsun 510) and installing a racing beat holley 600cfm carb and intake.



well......the gasket that goes between the intake manifold and the engine block....i think we put it on backwards.



we also put a little silicone gasket sealant on both sides of it.



i havn't removed the intake yet so in theory i could leave it like it is.



should i-



a. leave it like it is?



b. remove it, clean it and put more sealant on and reinstall the correct way?



c. buy a new one?



d. other?

remove it(clean the silicone sealant)

Dont use silicone sealant anymore(not recommended 4 parts where gasoline flows)

backwards shouldn't matter, the gasket is the same both ways. you actually do want a little silicon on both sides of the gasket, it helps seal any small leaks and it also keeps the gasket from sticking to the block, lots less gasket scraping

its all pretty much a matter of opinion, but I myself wouldnt use silicone in fear that some may get sucked into the engine.



If you have the paper gasket I would replace, but if you lucked out and bought the hard metal-like gasket with rubber lining the intake port holes of the gasket I would reuse once or twice if money is tight before buying a new one, but better safe than sorry. If you have the money for a new one, buy it.

it seems to be more metallic i guess, it's kinda waffered into 3 gaskets stuck together.



anyway, after reading the directions on the back of the sealant it says something to the effect of-



"do not use in areas which may come into contact with gasoline".
