Piston Ring End Gap - Depth?
When measuring piston ring end gap what is the proper depth to place each of the three rings? Car is 993.
Also, I assume the measurement should be taken at the cylinder end closest to the head, right?
Lastly, the ring end gap for the top ring is .2mm, upper limit .8mm. What are the values for the other 2? These values are not in the shop manual.
