I know about the endyn one but I have the plain ol' moroso one. Well my grommet that holds the pcv valve disintegrated and since I bought it used, I have no idea where to get another grommet. Tried all the automotive stores so now I think it's a dealer part No. There used to be a thread containing this info, but it was quite a few years ago. Pls, if anyone has the info, please pass it on. I'm running open crankcase at the moment .
