Is my car done for or can she be fixed?!

SOURCE: melted spark plug wire

You did not say if you were overheated,also what liquid and what is meant by spark plug filled with liquid, if plug was removed from block! (antifreeze?) Check oil and if water in it you more then likely have a blown head gasket. Hot engine is what most likely caused burnt wire. They make sealers that are put in radiators to repair leaks if cost is a problem and you are comfortable using them, and if not, have head gasket replaced which can be quite costly. Mechanic can determine cause with a compression test. Other things you would be wise to consider if installing new head gasket would be changing water pump,timing belt and crankshaft seal as while as the other belts that need changing.Of course this would depend on whether you planned on keeping the vehicle and if it was worth it. You can talk with a mechanic about using a sealer if this is the problem. I know of no other liquid it could be other then antifreeze.Oil is unlikely. P.S You might want to find out where the oil leak is and correct it before you do more damage!

SOURCE: car won't start wants to turn over but nothing.

sounds like you have a blown head gasket this would explain loss of coolant and running poorly excessive smoke.

SOURCE: Smoke comes from around engine

If you saw where the oil came out then that is the repair needed. It may not leak enough oil to get to the ground. Engine temp will make the oil leak smoke before it ever hits the ground. It may be valve cover gaskets because when they start to leak the oil gets all over the exhaust manifold and the exhaust manifold runs very hot. Rate if this helps

SOURCE: smells like burning oil, oil is running out under

Most likely cause is a leak in the valve cover gasket. Under pressue, a good sized leak will spurt and burn off on the manifuld, causing the smell of burning oil you're getting. This also would cause the presence of oil throughout the engine compartment. Best of luck on your problem.

Yes , power steering fluid will smoke if it gets on a hot engine, especially on any part of the exhaust system. Barring anything else wrong with the engine such as a coolant leak, and the engine running OK otherwise, I would say that the smoke is from power steering fluid dripping or getting blown on the exhaust by the fan.
