Crankcase Vacuum Regulator Location.

[Duk]

I'm fitting a Moroso vacuum pump to my 4AGZE and I'm using an Aeromotive vacuum regulator to control crankcase vacuum.

I need to know the best place to put the regulator.

1 option is to put it in the line between the crankcase (actually the sump) and the pump. This would be the easiest to do.

The other option would be to plumb the regulator into 1 or both the camshaft covers. This would be more work, but should help draw fresh air into the top of the engine and downwards towards the sump when the regulator is open. Whether that's a good thing or not, I don't really know

where does the pump draw from? i reckon you want to put it as far away from that point as you can really, dipstick tube may be a good contender. I'd steer clear of the oil drain as it might stop it being an oil drain.

LOL!
I intend to weld a pipe inside the sump that has a baffled inlet that lives above the oil level and below the crank. This pipe will exit the sump on the right hand side of the engine, below the crankshaft pulley. From there an appropriate hose will go up to the vacuum pump that will be driven off the inlet cam pulley/sprocket.

Put the air inlet/s in the cam cover/s then, easy!
