I'm replacing the head gasket on my B16A2.

Per the HELM instructions, I pulled out the head oil control orifice to clean, and replace the o-ring ... however, much to my surprise, there wasn't an o-ring!

Am I correct to assume foul-play?

I can't verify all of the history of this motor, and I suspect at some point, someone replaced the head ... most likely re-using the head gasket and bolts (which is why the damn thing has been leaking so badly with only ~100k miles on it.

I just can't imagine why someone would pull out the orifice without at least re-using the o-ring.

if you can get it just put it in. and you dont have to replace all the bolts, just get the head resurfaced and get a new head gasket.

Heh, turns out the alternator o-ring was also missing!
No wonder this thing has been leaking so much oil!
