I'm ready to re-install my intake manifold after a ton of work in the engine bay. Does the oil return tube need an o-ring on the intake manifold side? Real OEM shows the compression spring, washer, and o-ring going into the engine block but nothing on the intake manifold which doesn't seem right to me. Mahalo for your time.

Oddly enough I just looked up my car (euro 323i 1985) and this page doesn't show o rings at the top,
but this one does, but its "no matching parts for my car"
but the numbers it gives for the top items you ask about(10 Oring, and 11 washer) are the same numbers given for the lower items in my first link.
So i think its fair to say they are the same part number top and bottom.
