That would be great if you could check that and post a pic of the o-ring, let us know how it's holding up. It's really hard to tell when some feedback might be negative for some other reason. Maybe they didn't lubricate it well when initially installed and didn't want to admit it.Yes, I have a Mishomoto catch can, I empty it every 2-3 months. I've never opened the DV, just lubed it and installed it according to the instructions. IIRC, the manufacturer didn't have any recommendations for regular maintenance. But now you guys are making me curious, and maybe when I have a chance I'll pop it open to see how it's holding up.
It's great to hear you have a CC also. I was worried maybe you didn't and the extra blow-by was what was keeping yours oiled. Thanks for the info! I'll still wait to hear/see results of inspection.
