Some pics of my old bevel gear. The vent tube doesn't seem to have any type of valving in it, just baffled by the casing where it is inserted. Picture 003_1 shows the vent. The gear is situated such that the transmission would be to the right. There is very little clearance between the motor/tranny and the vent tube. All the seals have Volvo numbers on them, not sure if they are part numbers.
