Truck started burning oil overnight? Possible culprits?

Hey all:

I have a 95 Toyota 4Runner Limited V6 4x4 w/ automatic transmission.
It's been running like a dream up until this morning.
I drove it last night with no issues, but this morning upon ignition I noticed the idle was rough.
Once I got it out of the garage and began driving, it belched PLUMES of oil smoke out the exhaust - enough to obscure the street. Plumes.
There was also a VERY significant loss in power, especially in gears 1 and 2.
It also smelled TERRIBLE, like it was burning oil + raw eggs + kittens + cabbage at the same time.

My oil pressure gauge read normal, my temp gauge read normal, and there is NO check engine light.

What could have failed overnight to cause such a catastrophic change?

I have an appointment to take it in tomorrow morning for service, but am just wondering what might be the culprit before I show up.
Thanks in advance for any ideas!

    The rotten egg smell is often associated with a bad catalytic converter, I think.

    That's the best I can offer.

    My first guess and intention is to quote the Vin Diesel "Fried Piston Rings" speech.

    Failing that, check valve guides, and beyond that you've likely blown a seal or a gasket somewhere along the oil supply.

    This is true, but the relationship here goes the other way.
    A bad cat won't cause you to burn oil - but burning oil can foul a cat in a hurry.

    Was it white smoke pouring out?

    Take a look in your oil for white crap that could signify a blown head gasket. If water gets in there it will spew out piles of white smoke and you get a nasty smell from burning antifreeze.

    Did you fill your gas tank yesterday?

    Did you perhaps fill it with diesel?

    It was indeed white/blue-ish/grey smoke, but the truck is now at the shop so i'm unable to investigate the oil.

    I did not fill the tank yesterday, in fact it was almost empty from a full filling about 2 weeks ago.

    Man, I hope it's not a head gasket, that's an expensive fix.

    is it possible someone put something in your gas tank? it strikes me as odd that it was "running like a dream" yesterday and "obscuring the street" the next morning.

    burning a lot of oil combined with the described low-end power loss really makes it sound like a head gasket.

    Closure:

    It was indeed the head gasket that blew.
    The terrible exhaust smell that I detected other than oil was antifreeze.
    $950 to tear down the engine and inspect the damage to valves/exhaust components.
    $1450 for the head gasket and labor
    $X more to repair any damaged valve/exhaust/etc components.
    Basically looking at a $3k repair bill on a truck worth $4k - and i'll still be left with a used truck.

    Decided to trade it in on a new car, using the 'cash for clunkers' government rebate program ($4500 credit towards a new fuel-efficient car).

    I was at a dealer this afternoon looking at cars that I can get for my current SUV, if you want to know any details about the program, you can send me a PM or ask it here.

    Looking at getting a 2009 Hyundai Elantra Touring.

    We need something inexpensive, fuel efficient, with enough room for our little one/car seat for long trips, and hauling the occasional mass of stuff or piece of furniture.
    This thing prices out at $11,800 after the government truck trade-in and $1500 cash back - with the 10 year/100k warranty, large amounts of storage (fold-down rear seats), and good fuel economy.
    It also comes with all the bells and whistles as standard, hard to say no to.
    I can't find anything comperable in terms of price/warranty/storage/options.

    You could make the case it's worth the cost of a rental for a week.

    Hyundai is fifty times the car it was five years ago. They've done some amazing things insofar as bringing their brand up in quality.
