Went to check the catch can tonight. Been on a week or two?

Nothing in it except a few drops of oil vapors that smell like gas. That said the two pieces that act as baffles unscrewed themselves and fell in the can. One screws into the other. I screwed everything back together.


I have a feeling that the two pieces are actually supposed to hold a filter of some sort, but it doesnt come with one. I will have to come up with something to put in there, which will help the vapors condence easier, making the can more effective.

Grab a rattle can of clear coat and spray them before you put them on.

Have any of you had issues with coil whine in your NNBS? After 30/40 min of the vehicle being on, it sounds like I've got coil whine coming thru my speakers or coming out of the head unit itself- I can't tell which. its a pain because the radio is always turned on- even when you turn it off- because the alert chimes and turn signal sounds- etc all play thru the radio. It's almost headache inducing and I can't tell what it is- the head unit or the factory amp leaking the sound thru the tweeters.


Based on my experience with computers, and coil whine that I've heard come from graphics cards and/or standard ATX power supplies, I want to say its the factory amp causing my issue, but I don't have anything else to base that on.
