I have a friend who has a 2014 Z51 Stingray and he purchased the Elite "better" catch can with the clean side separator. He said that once he installed the separator, he can't remove the oil fill cap without loosening the entire reservoir mount. He says he plans on removing the separator. Is this a common problem with this aftermarket part? I was going to get one for my 2015, but now I'm not so sure.
