I installed the Mishimoto OCC last week, and while the install went smoothly, I noticed something and wanted to ask y'all if it's normal. I seem to have a "crankcase smell" coming from the vicinity of the catch can. It's not overpowering, but it's definitely noticeable when you first open the hood. There's no leaks that I can see. The hoses are tight and have a good latch, the catch can itself is screwed on pretty tight, and the plastic fittings are tight enough that I'm afraid to go any tighter for fear of stripping them. They have roughly 3 threads showing and are thread-taped. Is this smell a normal thing, and if not, any suggestions as to where it may be coming from?
