How do you check intake manifold?
Inspect the intake manifold where the runners, or tubes, attach to the engine. Using the flashlight, look for signs of coolant leaks. They show as wet spots or stains around the runners in minor cases. In severe cases of coolant leaks, parts of the manifold are wet with coolant, or puddles of coolant are present.
Is there a way to test the intake manifold?
If you have access to a diagnostic smoke dispenser, you can conduct a test of the intake manifold by placing the nozzle inside the throttle body and filling the manifold with smoke. Watch carefully for smoke coming out through the runners, or through cracks.
What happens if you have a bad intake manifold?
If the intake manifold gaskets leak coolant into the intake manifold the engine may overheat as a result, without any visible external leaks. Any coolant leaks should be addressed as soon as possible to prevent the possibility of serious engine damage occurring due to a bad intake manifold gasket.
What is the role of the intake manifold gaskets?
The intake manifold gaskets are responsible for sealing the intake manifold against the cylinder head(s). Apart from sealing engine vacuum, certain designs will also seal engine coolant.
Is the carburettor mounted on the intake manifold?
Except where the superchargers or governors are used, the intake manifold is constructed so that, when the carburettor is attached to it, the mixture can reach each cylinder. The carburettor is mounted on the intake manifold.

What is the runner control on an intake manifold?
The intake manifold runner control is an engine management component that is found on newer intake manifold designs. It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners.
