S2 Valve Cover Question
I'm in the process of bringing my recently acquired 89S2 back to life. Of the many problems I'm finding, this one has me puzzled at the moment. On the valve cover, there's two ports that appear to serve no purpose. They were held in with RTV and a snap ring. I can't imagine this is right so I started to look at my box of parts and I found two green o-rings that most likely should go here. After searching for a bit on the forum I found a parts diagram that shows an o-ring and a snap ring there which makes sense. Here's where I'm having issues.
1. How do I get this assembled properly? If I put the o-ring in place first it sits in the groove for the snap ring and I can't get the snap ring to seat properly. If I put the snap ring in place I can't get the o-ring under it. It seems so stupid, but I can't seem to get either way to work.
2. What's the purpose of the two ports?
Thanks in advance for any help with this.

Did you remove the rock hard remnants of the original Oring? It will take some work to remove. The plug should be easy to install if you did. Also there is a notch the plug sets into.

Oh yeah, all the remnants of the original o-ring are gone. The plug goes in just fine, it's trying to compress the new o-ring enough to allow the snap ring to seat that's giving me problems.

There should be no issue. I have replaced these and never had a problem. The o ring is on the sides of the plug so it shouldn't stop the plug seating flush with the cam cover.

So the o ring goes on the inside of the valve cover then? That makes sense since the ring on the outside does not allow the plug to sit in the notch. But with the ring on the inside its difficult to get the snap ring in place. I'll muscle it in if I know it's in the right spot. I don't recall an old one being on there when I disassembled it. Which explains the oil I've found.

The o ring goes in the groove on the side of the plug. Make sure you have removed the old one - it will look like black plastic by now so you might not realise it is the old o ring.

The S and S2 16v's are like this, and you have to get the old o-ring off. I did my valve cover recently and thought the same thing, "I can't compress this enough". However I didn't get the old o-ring off, once I did and put the new one in its place it went together easy. The old ring was completely flat and squared off, which made it so I didn't recognize it. Looked like black plastic.

I'm ordering my parts for the valve cover replacement and want to make sure I replace these types of things. Can someone tell me exactly which part is being talked about in this thread? Thanks

Look at your valve cover. There should be two black plastic caps. When you remove the cover there will be two snap rings to remove these caps. Check the PET for the oring part numbers.

Sure enough. Once you said that it looks like black plastic it all made sense. I got the old one off, new one on, snap ring in place, and waalaa! Good as new! Thanks so much!
