Intake manifolds
reside on the top of the engine.
Intake manifolds sit on top of the engine and transport air and fuel into the engine's combustion Hospital ward. The intake manifold too conveys vacuum and coolant wound up the action. An air leak in the intake manifold can advance to empty-handed indolent excellence, empty-handed fuel economy, stalling and worse due to hoover loss. In that an air leak leaves no visible traces, pinpointing one can be a bit trickier than finding a customary coolant or fuel leak.
Move any components aside that block your clear view of the area you pinpointed in Step 3 and look closely until you spot the leak. This may require turning the engine off and removing components, such as the air cleaner assembly, to provide you with a good view of the area.
Leaks Frequently seal themselves as the intake swells slightly when brought to abundant operating temperature.
2. Raise the hood and use the flashlight and inspection mirror to perform a visual inspection of the intake manifold. Look for any signs of cracks in the manifold's surface. Depending on the year, make and model of the vehicle, you may need to remove an engine cover, move hoses aside and use the inspection mirror to see the entire surface of the intake manifold.
3. Spray the carburetor cleaner in quick spurts over the intake manifold, one small area at a time. Spray once, then listen to the engine idle. If the idle does not change, move on to the next area. Continue doing this until you hit a spot where the engine idle responds to the carburetor spray.
