Where is Volvo v70 oil trap?

Below the intake manifold on the passenger or right side of the engine

I own a 1998 v70. the oil trap is behind the intake manifold on the left side. FCPgroton sells the repair kit for it.

As I stated the first time it is on the right or passenger side of the engine. You will need to remove the intake manifold to service or replace it. If the oil is changed often enough the oil trap box will not clog with carbon The clamps on the original box are not reusable and you will most likely find that the hoses going to and from the box are also clogged or at least restricted with deposits also. I have over 30 years of dealer experience.
