How to Identify an Intake Manifold on an Antique Automotive V 8

The intake manifold on old engines provides the entryway of fuel and air into the engine and eventually the combustion chamber, where it turns to energy, powering the engine parts. Identifying this critical channel is fairly easy on old engines, since its connected to the carburetor, which performs the air-fuel mixing prior to going into the engine.

Instructions

1

Park the car in a place that is easy to work in if the car can be moved. Lift the car engine hood and prop it up to stay open on its own. Locate the carburetor assembly on top of the V-8 engine.

2

Use a flashlight to help see the engine parts if you cant see well with the regular room or area light. Locate the exit side of the carburetor where the air-fuel flow will go to the engine. Look opposite the side of the air filter and fuel lines connected to the carburetor.

3

Follow the carburetor to the metal tubular channels that go from the carburetor into the engine casing itself -- this is the intake manifold. Note how the manifold is bolted to the engine case to maintain its connection.

4

Check underneath the engine if the intake manifold is not visible from the top exiting the carburetor unit. Look for a manifold that enters the engine from the side after looping downward vertically from the carburetor.
