Mann Hummel Pro Vent Plumbing

[whitepark]

I have a 416 LS3 in my Camaro. Dart block and heads, Holley throttle body injection - 600hp. Currently the engine vents into a firewall mounted catch can (see catch can beside a/c firewall lines), with vent hoses plumbed off the back of the thick spacers which sit between the engine block and coil / valve covers on both banks, and thus both sides of the engine feed into the vented catch can - venting to the atmosphere.

I'd like to go to a Mann Hummel closed vent system, draining back into the sump and I am seeking plumbing advice.

Is the plumbing as simple as taking the existing hoses from each bank and plumbing them into the Mann Hummel Pro Vent 200 can; plus routing the Mann Hummel drain vent into the LS3 sump?

that's some nice plumbing! Love the vent on the upper radiator hose.

No it is not if I understanding you correctly. You need an inlet and an outlet, not two inlets. I would think you also need a source of clean air.

Instructions are here.

Thanks Carl. I’m so used to using the stock valve covers this never occurred to me.
