I just went through the process, use a small length of plastigauge, like .25 inch or so. Lay it length-way in line with the crank and away from any openings in the bearings. Put the cap on and torque it properly, don't spin anything! Take the cap off and measure the squished plastigauge. Look for between .001 to .0015 clearance. I'm sure there are other opinions.
