jt1 Posted August 3, 2004 Share Posted August 3, 2004 Like this one: http://www.moroso.com/catalog/categorydisplay.asp?CatCode=13023 If so, a couple of questions: Did you use any kind of baffle below the separator in the valve cover? My stud girdles are very close to the valve cover and If I can use any baffle at all it will only be a flat piece of aluminum. How far did you let the tubes protrude into the exhaust? And lastly, how does it work? Good, fair, or waste of money? John Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted August 4, 2004 Share Posted August 4, 2004 Can't answer your question because I haven't used such a device. But in the current edition of Engines magazine they installed a vacuum system on the crankcase and picked up an additional 15 HP. I have never heard of such a system, but that is not a bad power gain. Quote Link to comment Share on other sites More sharing options...
jap tin Posted August 4, 2004 Share Posted August 4, 2004 If you are running mufflers you are better off using a vacume pump. The header evac systems don't work very well with mufflers. I pull vacume from the right front top valve cover with no problem of sucking excessive oil. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 4, 2004 Share Posted August 4, 2004 If you do decide to go the exhaust route Mr Gasket has a setup that is about 1/2 the price of the Moroso stuff. Quote Link to comment Share on other sites More sharing options...
mark Posted August 4, 2004 Share Posted August 4, 2004 John, Did you have more problems with crankcase pressure at Kershaw? Quote Link to comment Share on other sites More sharing options...
jt1 Posted August 4, 2004 Author Share Posted August 4, 2004 Mark, not bad but some. It was still blowing just a little oil out the breather with the dipstick zip tied down. Just enough to see a few droplets on the valve cover and plug wires. Obviously it's not venting enough. It's sucking oil into the intake thru the PCV valve, since I can't run a baffle under the PCV, stud girdles in the way. I was thinking this system would vent the crankcase a little better, eliminate oil into the intake, blowing it out the exhaust instead. I'm either gonna try this or use a breather tank setup like you've got, haven't really decided yet. If this setup doesn't work well with mufflers, that's gonna be a big negative. For those wondering what I'm doing, I run my car at open track road course events, turning high rpms, 7K, for usually 20-25 minutes at a time. I'm using a PCV valve on the pass side and edelbrock breather on the drivers side, and blowing a little oil out the breather and sucking some thru the PCV. No baffles on either on due to clearance problems. Motor is fresh and leaks down good, but isn't venting enough. Suggestions are welcome!
