Hi John

Is it pipe #18 on the diagram below that is flattened?

or is it part #28 in the diagram below? If it is #28 then that should be flattened and sealed. It needs taking off occasionally and emptying as it condenses and collects water and emulsified oil from the engine such that it doesn't go into the airbox.
