Well, I figure about 2 qts too much. It pushed it out through the tube that comes out into the top of the airbox. Oil was sucked in through the AFM and TB and intake plenum. I stripped the threads when I pulled the plug. Half of the aluminum threads came with it. I bought a kit and took my time boring it out by hand, with grease on the bit to catch the filings. I then rethreaded it and cleaned it out and ran a magnet into the threads and cylinder to catch anything and then used my shop vac with some vacuum hose to suck out anything in the cylinder.
