It's always a bad idea to run engines, especially diesels, below operating temps for extended periods. Crankcase dilution is the major problem but gum and laquer deposits are also bad news. The specs for the 6-71TI's (on most 460's) are only slightly different from the 6V-92's. The 71's operate between 160 and 185, and the manual recommends that if you need to idle for a long while (like waiting for those damned bridges in Virginia), to keep it above 800rpm. In my case, I run at about 1350 rpm which yields about 8.5 knots in slack current (any more than that and she starts to squat, any less and she's too cool). I'm pretty paranoid about what's going on in the engine room so I do visual checks about every hour or two. Those checks include temperature checks at various points on the engine and transmission utilizing an infrared gun. Generally, my coolant temperature is about 165 at the thermostat and my oil temp about 230 at the pan, both of which are in line with the specs. Nevertheless, I still put the balls to the wall about once a day to blow it all out and to make sure that everything is working as it should. I'm running about 200 hrs a year and do an oil analysis annually to make sure there are no developing problems. I'm showing 1400hrs now and so far, everything is looking normal with no perceptable dilution. I have thought about putting smaller engines in when it comes time to repower but then I would lose the ability to dodge a storm and probably market value, too. I'm also swapping out my analog oil pressure and water temperature gauges for digitals (merry christmas to me!) but I'll still do visual/manual checks. I really do like to monitor those engines closely. __________________________________________ __________________________________________ __ q=1572752729094&id=a94e0df1ab2ede56c2c848ace 5605cc0"> earrings.html">Tiffany And Co Earrings necklaces.html">Tiffany And Co Necklace Cheap Tiffany Jewelry rings.html">Tiffany Engagement Rings Back to Top
