Instead of just draining the pan and refilling I decided a complete flush was the way to go. My accusump, sump line, oil cooler and cooler lines hold an additional 5 quarts that I wanted completely flushed and refilled on each change. I built an IOD ( improvised oiling device ) from a $25.00 K-mart pressure cooker. </span></span><a href="http://s698.photobucket.com/user/TR4jim/media/Intake/preoiler.jpg.html?sort=3&o=0" target="_blank"><span style='font-size:10.0pt;font-family:"Trebuchet MS",sans-serif;color:#336699;background:#F9F9F9'>http://s698.photobucket.com/user/TR4jim/media/Intake/preoiler.jpg.html?sort=3&o=0</span></a><span style='font-size:10.0pt;font-family:"Trebuchet MS",sans-serif;color:#333333'><br><span style='background:#F9F9F9'>With that I can isolate and plug in to the accusump, sump lines, cooler and cooler lines and run through heated cheap oil for the flush and refill with VR-1.</span><br><span style='background:#F9F9F9'>This went a long way to improving the oil quality over the life of the motor.</span><br><span style='background:#F9F9F9'>I just tore down the motor after two seasons and it's in the best shape ever.</span><br><span style='background:#F9F9F9'>If not for losing some clearance on the # 2 main I could have just put new bearings and rings in it and ran it again.
