Volvo vacuum whistle
Posted to Technical Discussion Forum on 8/13/2008 5 Replies

We have 20005 Volvo S40-t5 in the shop with a loud vacuum whistle. Remove the oil fill cap and the noise goes away. Seems like excessive crank case vacuum also. We normally never work on Volvo's so any help would be appreciated. Login to read more.
