Chrysler Repair: 2000 neon bellows tube, differential air pressure, collaps

Question
QUESTION: Over the past 6 months the Bellows tube from the Throttle body to the Engine collaps after starting then leading to failer. I have had this this tube replaced 3 times so far. My mech does not know what the problem could be? any suggestions would be great. thank you.


ANSWER: Hi Brian,
What engine do you have, and what part of the engine does this tube connect to? I don't understand because the throttle body is usually mounted on the intake manifold so it is already attached to the engine?

QUESTION: Roland, I ahve the 2.0 Sohc. All I know is the Throttle body is attached to the Air box just below the batterie and then the bellows tube runs from it to the intake? the problem I am having is the engine is sucking so much air from this tube that the tube keeps failing.
Brian


Answer
OK, that is what I pictured. The only way for the tube to collapse that way is if there is a obstruction in the airpathway from the air intake...through the filter box... through the air filter and into the bellows tube. I would start at the air intake in the front of the car and see if there is rag/dead animal/etc. stuck in the air pathway. The intake manifold/throttle body will suck on that bellows and if the other end of the pathway is somehow plugged up the bellows will collapse due to the differential air pressure between the environment vs the near vacuum caused by the engine sucking on it.
