I put a bypass setup on about 30k ago. I always notice oil residue at the filler cap where the nipple enters the center and there is a O ring there. Figured it must be normal, but there is also a lot of residue around the CCV filter where it comes out of the valve cover. I also have oil in the intake. I just read a post on another site that also mentioned that the way the bypass systems work, they can actually make the CCV systems even worse. Anyone know if this is the case?
