Now I have more questions, it appears that you only need the check valve if you are draining back above the oil level.....?
If we plumb the Pro Vent as Mark described in the clean side, between the air intake and the dry sump tank, which way is the air flowing? Normal operation, fresh air flows through the air filter, past the MAF, into a hose through the Pro Vent and into the tank. No need for an air oil separator in situation.
Under heavy load, that air flow reverses, out of the tank into the Pro Vent up the hose and into the intake tube. We don't want oil there at all.
Do we follow the arrows on the pro vent for for the former or the latter?
This may become painfully obvious when I hold it in my hand.
Thanks again! |
Thanks for posting the catalog. I also have other questions that will require some thought. I am using a large, 5-stage pump that will pull a lot of vacuum. The pump manufacturer suggested I use a vacuum regulator (available from Peterson) to control the vacuum at 12-14 hgM. I am concerned that if I ever reached a positive crankcase pressure situation (my engine builder says I won't) there would be no pressure relief and I might blow oil through the seals. Peterson also makes a check valve designed to release pressure (back to the tank) for that condition, but I'm not sure I need it. My motor goes on the dyno Thursday so maybe I will get a better feel for how I should proceed after I see what the crankcase vacuum looks like. Any thoughts from you or Mark? Thanks
