Did you add oil to the air system?

Yes, at one point.
But before I changed the valve block.

Perhaps the air drier is blocked from the oil. That the incoming air and outgoing air passes through it.

Where is the air dryer located? On the pump/block assembly under the car?

Can it be removed? How?

Can it be cleaned? How?
