ok, so i changed my oil for the first time (since ive owned it) on my 08 6.4 about 2 months ago, 2500 miles ago. when i changed the oil, i poured it in, and let it wait a couple minutes and then checked the oil, got the level perfect then. I decided last night to check the level just to see how it was, and it is about 2 inches higher than it should be on the dipstick!! it is kinda dark but doesnt seem to have anything in it (coolant, fuel, etc). is it possible that i just overfilled the oil because i checked it too quickly after i poured the oil in? i watched the DVD that came with the truck last night and it says to wait 20 min after driving before checking the oil so that it all drains to the crankcase. (it had been sitting for over 24 hours when i check it yesterday). i hope thats the only problem, but i hope that didnt cause any other problem too... any advice here???
