My mistake, I didn’t read much of the thread. I will look for it now!

Radium would be one of the last brands I’d think would have an issue! Their catch cans are very popular and receive high praise.
After doing some re search here its a 2 piece system like the oem one. Theres a gasket that seals it that has reported some leaking from members. What they've done is opened it and sealed it with hondabond. Where the mishimoto is a single all aluminum one piece so it cant have that issue.

This is why I proactively changed mine
Might be next mod for me but a part of me wants to hit three years first. So I can just do a quick drain and fill “flush” too. In 3 years time I should hit about 14-16k miles

The leaking Radium was on a post on this thread here, that's why I mentioned it. 250 is a nice deal but I gotta fix this ASAP! My car still has warranty but I dont want to replace it with another oem piece just for this to happen again.
Just make the dealer replace it.

If people with leaks don't make the dealer replace it they'll never fix the part longer term. This is how TSB are born. I hate the acura dealers as much as the next guy, but I don't think I've ever seen as much disdain for going to the dealer on any other platform as I have here 🤣. Kind of wild people still buy these cars from them with so much hate, lol.

I'm still on the stocker with tuning and a ton of track time...no leaks. Some evaporative loss first time on track and after I added water wetter. Both normal scenarios to have fluid leave the drain tube and pool a little.

It's been an issue since the fk8. If they didn't fix it by then there not going to do it now. Also I'm not using my car as the martyr to get them to change the design.

Fair play. I get that.

I've seen a lot of photos that aren't actually failures, but just evap or purge from fast heat or g force. Yours is the first I've seen in a while that's an actual leak. Sorry to see it.
