I have a 1996 Ford E350 Super Club Wagon with a 5.7L V8 Automatic Tranny.
I purchased the vehicle from original owners knowing it had this problem. After running for 10 minutes heavy amounts of gray smoke from the exhaust (dual exhaust and equal amounts from each pipe)and the oil is gone from the pan. We replaced all gaskets on both sides, pistons looked ok. Passenger side of engine was full of oil/antifreeze (looked like chocolate milk). After putting everthing back it started and ran like a champ for 10 minutes. Same problem, lots of smoke (as much as I imagine could possibly come out of the exhaust) and newly filled oil pan was empty. No oil anywhere outside the van.
What did I miss?
Thank you in advance, and type slowly, I'm not that smart.

It's not critical for now but your listed engine size is not a listed engine for the vehicle?? Duals? Didn't think was was orignial either.
Ok: The symptoms are a match with major head gasket problems or cracked major engine parts. Do I need to type slowly to say that isn't a good thing?
Finding oil empty is bad enough. Running it that way may have finished off this engine sorry to say.
We know it has problems but just what did the previous owner tell you about it?

Thank you.
Sorry, 5.8L V8 (its a ford 351 engine). Definitely two exhaust pipes, could be split after the fact, I don't recall right now but I will check.
The previous owners drove it home from vacation, it overheated and they kept driving it home.
I did not run it completely dry as far as the oil is concerned (since I've had it). In ten minutes it went from 6 quarts to a small stain on the dipstick. No oil on the ground. Wondering how it could get sucked in so quickly with no obvious (from a visual aspect) engine issues, when we had it opened up everything looked intact.
I only gave $300 for it, it is a nice van otherwise, just trying to salvage the engine if at all possible.

Ok - a 5.8 and twin tail pipes is likely an original set up. When you said 5.7 (famous GM V8 and duals) I thought this could be some custom set up.
Just how far did you dismantle this engine for inspection and what was replaced when you did that? Just a valve cover is not far enough.
When oil, anti-freeze get mixed, smoke out exhaust, no leak on ground seen now, then the engine is taking in and mixing up the show thru gaskets (head) or flaws in anything that keeps all this separated and the engine is managing to suck it into combustion and try to burn it.
At a minumum top end (intake manifold and heads) need to be removed for inspection. Not sure how easy it will be to tell if the engine overall has been damaged to a point where you would consider an whole replacement as the more cost effective way to get up and running with this. Some serious diagnostics are called for to know the best approach for this now. Compression as best you can while intact and go on from there. I'd like you to know as much as you can before investing in this engine only to find there's so much more wrong that it was a lost cause money wise vs whole replacement components up to a whole running engine used if you would consider that approach,
