    Default EVAC ?'s

    Finishing up. My headers have the bungs for a EVAC system, my valve covers are tall and plain (smooth, no holes anywhere). I want to add bungs to my valve covers, somehow? What parts do I need for a EVAC system and where do I get them? Thanks!

    Im just running puke tank off the back of one valve cover. Serves the same purpose, different idea.

    I think for the evac you'll need a way to get the hose from the valve cover to the header, whatever fittings you need depends on the design approach, and some pcv valves.

    +1 on the Moroso kit. I've used it on a couple boats and our race cars. Best deal going for this style crankcase evac system. The puke tank works too, but you don't get the added benefit of pulling a crankcase vacuum (depression I think we decided the term is ) with a puke tank. Blown applications seem to prefer a puke tank though....

    Default Liquid oil

    Something to remember, a low breather tube to the headers or a puke tank will allow liquid oil to be pulled/pushed into the hoses and the headers/tank. For a puke tank use tall extensions, (4 to 6") before the turn to hoses, and for headers use a tall extension and baffles in the covers because the vacuum effect will pull liquid oil out with the air.... PCV valves are not necessary with these type of breathers. The PCV system is primarily for closed systems with one breather in and one out, and they actually work quite well........MP
