Thanks Justin for your great advice! right, one bolt on right should be strong enough to hold oil trap. i will take the intake manifold and oil trap out again to check all wires to alternator (and missing bolt). Thanks again

Hi Justin, first of all, thank you very much for your wonderful post. I have 98 s70 turbo volvo and replaced the PCV system this weekend by following your detailed instruction even I do not know car well. really appreciate your help! cut story short, I bought PCV kit from FCP ($115.00 plus shipping)...
