I have not followed this thread, but the boroscope keyword caught my attention. I have used an Olympus boroscope with Sony digital camera to examine the oil pan and crankcase cavitation/areation problems in my I4 conversion. The details are in the archives. In quick summary, the interior is easy to inspect with the boroscope in a static mode as you might expect. Unfortunately, key areas like the oil pickup inlet are inaccessible because of the size of the boroscope probe (1/8 inch diameter). The internal contrast ration is very poor - black on black and it is difficult to image below the oil surface. When running, the crankcase is a maelstrom without the windage tray in place. As I described previously, you can see the oil quickly foaming in front of the boroscope pickup. With the addition of a windage tray and set of oil baffles with directional flow doors, the oil system is very well behaved - looks like black rain pouring in fine streams. Any chance of discerning a paper shop towel texture in the black on black static system would be dubious at best. Frank Grunthaner In a message dated 9/14/06 8:47:34 AM, trclark@SHAW.CA writes:
