1990 F350, 7.3, 5 speed, Banks Sidewinder turbo. No clue of real mileage, last title change said 275K, I've probably put 20-30K miles on it since buying it, but odo currently reads 33K... So I don't really know, lol.
Truck was off the road for about a year, only occasionally fired up to play musical vehicles on the property to get to other vehicles/trailers that were behind the truck.
I've put maybe another 1K or less on it since putting it back on the road, seems to be running fine until today.
On the way to work, cruising at 65mph, I start noticing a faint burning smell, kinda like a trash fire in the distance. Truck still running good, gauges all look normal..
About a mile or two later, I get off the freeway, truck starts running rough, and it's BILLOWING white smoke out the back... Seriously huge cloud. I pull over and shut it down, pop the hood, and everything is absolutely soaked in coolant. I tried firing it up again, restarts immediately, feels like it's missing on a couple cylinders, still blowing a huge amount of white smoke, and notice it's also dropping raw oil out of the exhaust.
I let it sit for about 30 minutes, and then limped it into my work parking lot a mile away so I wasn't sitting on the side of the road. Stopped smoking, but I could just be out of coolant, lol. Definitely running rough, but not as bad as before.
No evidence of oil in the coolant overflow bottle, or coolant in the oil based on dipstick condition, and oil isn't low.
I've blown plenty of head gaskets in cars over the years, but I've never had one that sends raw oil out of the exhaust when it happens. But I've also never really got into diesels other then this truck either.
Still with the truck at work, so haven't been able to do any kind of real diagnostics... Does this sound like a simple head gasket or gaskets gone (I'd replace them both anyways), or something much more terminal within the motor to the point I should be thinking rebuild trying or looking for another motor and/or truck?
