Need a better PCV breather, I think. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm still working the kinks out of the engine in the sig. Today I finally realized what's been causing my oil leaks. With two 3/4" bottom vented Specter/Mr Gasket breathers installed one in each valve cover, oil starts to bubble out between the head and intake manifold once the RPM's get above idle. When I pull the breathers out, the oil stops leaking.

I'm guessing this means I need something a little more performance oriented. What kind of breather should I install that will work correctly?
