 Actually...

While the rotor-to-housing clearance is VERY important, what I found to be often overlooked is the rotor-to-rotor clearance.  The max clearance between lobes is .006".

I've installed rotor w/ as much as .012" clearance between lobes that WILL pump oil.  However, it does take much longer to build pressure at start-up, and max pressure at temperature is limited.
