When starting car warm, a moaning noise eminates from the engine compartment. It seems to be related to intake manifold vacuum and lasts for about 10 to 15 seconds immediately after start up. The moan is loud and is not associated with the brake booster. The problem is temperature sensitive and does not occur on cold starts. Any suggestion as to the source of this noise is greatly appreciated.
