Just got back from a two week 4200 mile run thru SW USA....with no break downs.
1) MPG ranged from a low of 13 to a high of 19 but with the overal trip average coming in at around 15.5 mpg. 90% interstate driving at 75 mph. Van loaded with about 900 lbs of humans and about 800 lbs of luggage etc...
2) Had one weird event...observed a cloud of whiteish smoke coming from back of van while going 75 mph on interstate. only lasted for a few seconds then gone. No noises, no change in speed, RPM etc...just smoke. no codes on Scanguage either.
Kept driving...all was well. Check out van at next fillup and engine and Tranny levels were fine. noticed oily film on back doors of van and several oily spots on underside of van (tranny pan, muffler, cross member etc.. Residue did not smell like either tranny fluid or engine oil and was light in color. Will crawl under van this week and see if I can pinpoint source.
Anyone know if the NAG1 has a pressure relief mechanism that might dump fluid for some reason or another?
