I'm building a 383 LT-1 with an Eaton M112 on it. In the past I've had problems finding an acceptable crankcase evac setup to handle the blow-by, and to prevent blowing oil past seals and gaskets. Anybody using a vacuum pump of any kind? Valve cover breathers tend to leak oil and smoke a lot.

 

You might want to take a look at www.blowerworks.net
Greg Carroll has a nice setup that should work for you.

 

I don't see anything on their site about crankcase ventilation. Did I miss something?

 

Click on the "what's new" above the picture of the Corvette, and it will bring up the info about the redesigned bracket for the Vortech blower. Scroll down a few pages, it's in there. (ON PAGE 21)
