I have an '04 powerstroke F350 with 140000 miles, while pulling a trailer it started losing power and did not want to downshift, it's an automatic, I stopped and it started blowing heavy white smoke. I shut it down and found oil in tailpipe and some fresh oil on front right lower corner of engine. Coolant was fine but after 5 minutes it had emptied resiovoir. Not enough oil used to notice on dipstick.Gauges had never moved from from normal positions then when coolant disappeared turned switch to on and coolant temp had rissen but never got hot. It has done this under load before but it was on very short load times when got out of hard pull whould go back to fine this was the first long interstate pull since I got the truck. It has been serviced since new at the ford dealer using their recommended ford 10w30 since the guy who had it before me never pulled anything. I asked and they said to stick with that unless I was going to pull a lot occasional trips would be fine. I have a 99 f450 I pull with local and I bought this king ranch as an interstate truck. There have been no modifications to the truck to my knowledge.

I've seen Modulator on Transmission, leak and allow fluid to be sucked into intake causing White smoke?
