What can I do to fix the intake manifold?
Method 2: At first turn off your engine. Then pressurize the intake manifold with less than 5 psi of regulated air. Now spray soapy water on the suspected area. You can use a spray bottle for soapy water. You need to spray several times to find the exact leak point. If you see the bubbles, then you can confirm the leak points.

What’s the purpose of an intake manifold gasket?
On these setups, the intake manifold gasket functions a bit like a head gasket, in that its purpose is to seal against both air and coolant leaks . Naturally, if this seal were to be worn out or damaged, then coolant fluid will be able to seep through the seal and leak out.
