Using RTV sealant on a preformed intake gasket is generally not necessary, as these gaskets are designed to create a proper seal on their own. However, applying RTV sealant at the front and back of the intake manifold can provide additional sealing protection, particularly in areas prone to leaks. It's essential to follow the manufacturer's recommendations for the specific gasket and engine application to ensure optimal performance.
You need the sealant on the ends where the supplied gaskets don't cover fully.
no, but you can replace the gasket entirely add the sealant ensuring a leak free fit.
By chance, did you use sealant when you put the new gasket on? If not, there is your problem.

The Intake gasket is leaking, NOT THE HEAD GASKET. Replace the intake gasket
Either V6 or V8 follow the top radiator to the motor and it will be there under a cove you have to unbolt. if it is a 3.8l v-6 there is two 10 mm bolts that hold the thermostat "goose neck" onto the lower intake manifold. suggest you slightly drain your radiator a bit and remove the two bolts. you do not have to take the upper radiator hose off. once the assembly is off, then remove the thermostat and discard the gasket. with new gasket and thermostat available, remove all the old gasket sealant from the " gooseneck" and lower intake. apply new gasket sealant to the gooseneck and place the thermostat into the gooseneck. put the new gasket onto the sealant and reinstall onto the lower intake. do not over tighten the two bolts. alumminum intake vs steal bolts, will cause the threads to strip out of the intake manifold and you will have larger problems.
I'm sorry but i actually have a 99 Malibu and they do have a intake manifold gasket which are commonly mistaken for a head gasket when it blows. Mailbu's 97 to 2000 are bad for them blowing. it is located on top of the engine. it's still very expensive **tamnesha Some Chevy engines of that period didn't have a gasket; just a thin film of sealant.
No, You don't put anything on Head, Exahust or intake gaskets. CJ actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets. =DK
It is possible, however like you said it is temporary. It depends on how bad the leak is. I would suspect it would work, typically the whole will be small enough to work with that type of sealant.
The intake gasket is the gasket that conncects from your air filter into your intake manifold
Remove the air cleaner and air box. Disconnect hoses and mark them so you know the proper reconnections. Remove the nuts and bolts holding the carburetor to the manifold. Remove the old gasket with a scraper and clean any remaining residue with degreaser. Clean the degreaser off completely. Apply gasket sealant to both sides of the new gasket and apply in place of the old one. Repeat the process in reverse order to place the new carburetor. You'll never see a carburetor installed from the factory with sealant. It's not necessary, and can cause problems if any of the sealant gets into the intake tract.
The only fix for a bad intake gasket is to remove the intake manifold and replace the gasket.
