I started to dig into the trunk leak this weekend since my coolant line parts aren't all here yet. But, do you happen to have the part numbers for those 8x pieces? I think I found that trim piece that they go into (212-693-10-33-9051), but there is no associated diagram for that part so I can't find the push-in pieces.

I want to have those on hand when I start investigating because they will definitely get destroyed on removal.

Thanks 👍

EPC.... DEATH BY A 1000 CUTS

it's a self-sealing rubber rivet - They are not going to leak now if none are missing and you were gentle upon removal.

Ohh, so the female part of the rivet is rubber and not plastic Cali ?

Awesome, you're the man. Thanks a lot!

I know there's a good chance that mine will be no good after I pull them out because as I started to remove one to get an idea of what they look like, I could see that the rubber is disintegrating already...

Just in general, any time I'm messing with plastic fasteners, I try to have some extras on hand because they're always breaking. I already have a little pile of most of the common clips, but these are new ones to me.

Take many photos please when you have removed this plastic strip.
I want to see how the plastic sits on the metal and how water may someday leak thru

Thanks

I just wanted to make a quick update that I ordered some seal parts when I last posted on this thread with the expectation that I would need to replace some seals while poking around to discover the problem, but I didn't get to it for a little bit and the leaks stopped happening.

So this issue is tabled until it recurs...

OK, so I was removing that chrome plastic piece because the chrome was flaking off. I ended up making it black and putting it back on instead of replacing it with another metal film wrapped piece just to see if I could. In the process, I removed the trunk liner and a lot of the parts mentioned previously in this thread. The pics were very useful.

Since I had easy access, I replaced the foam seals behind the lights in the trunk lid.

I have not touched the plastic pieces on the sides of the trunk because I determined that they can't possibly be leaking (yet). They would be dumping water into another region if they were.

Since I replaced the foam light seals, I haven't had any new water intrusion. But, it was sort of intermittent before, so I can't guarantee that the problem is fixed.

I noticed a few other seals on the black plastic piece external to the trunk lid where it interfaces with the trunk that I can replace next. And there are some orange plastic clips that snap from the black plastic piece into the trunk that don't seem to have a dedicated seal. Fresh orange plastic parts or possibly adding some tiny O-rings to these might be a solution if leaks are coming from there...
