Most common is the PCV hoses. They go from right side in front, Just behind the exhaust mani, all the way around over the transmission, to the intake manifold. As it turns 90* towards the intake, at that bend is usually where it will crack, or get so soft it will collapse , while the engine is running...also check the throttle body gasket .
