Cause spark plug blow out

SOURCE: sulfur smell from car real

You either have a faulty battery or it is being over charged by alternator.
Have the output voltage checked, maybe faulty regulator.

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!

check your cam position sensor (CPS) these can sometimes go bad.you should be able to find this sensor,on top of the engine,between the valve cover and timing cover with 3 or 4 wires coming from it.
however, the valve cover and timing cover might need to be removed, so some digging is involoved.good luck.
