Although applicable to the 7 and 9 series, this should get you started.

Just take the flame-trap out. It isn't needed. Later versions of the same engine (in the S70 and S60) don't have a flame-trap.

If the oil change maintenance has been neglected, the oil trap (a plastic box under the intake manifold) will get clogged up. Because of its design, it's almost impossible to clean out, so replacement is a common repair.

Thank-you for the response. However it appears that the flame-trap only applies to non-turbo engines. Mine is a turbo so I am probably dealing with the oil separator.
