Thread: Valve cover breather ?

Why would you think that would be a good first "mod"? You'll lose vacuum, so I guess if you consider that a benefit go for it...

Read this article on how PCV systems work. HowStuffWorks "How does a positive crankcase ventilation (PCV) system work?"

As Spade said..you'd create a vacuum leak by putting on a breather. If anything..it'll only cause issues.

If you are looking for appearance type stuff. Consider fender or full body stripes, painted calipers, maybe some interior trim pieces painted.

There's a company on eBay that makes beautiful polishes billet aluminum oil caps for 3800s as well.
