My Toyota Cavilier leaks oil badly when running can't seem 2 see where its cumn from leaves big puddle of oil can sum 1 help

Pretty hard to see from here. First I'd check to see if the oil filter is tight and the seal is secure. After the engine is shut off, and some drips still dropping down, place a large piece of cardboard under the engine.
This will pin point the area leaking the most. My best guess, an oil pump seal. But could be power steering! If it's redish, then maybe a transmission cooler line.
Either way, you need to have that looked at asap! And take the cardboard with you and show the person looking at it.
