I'm guessing that the guys here area going to need a little more info, like where is it leaking from? Upper or lower? Other parameters? Last oil change? what kind of oil are you using? You need to give more information to get a better respose. welcome to the club.

Burning a noticeable quantity of oil would be a blown headgasket or piston ring. Is there an external leak as well as burning?

Burning oil will come with a blueish exhaust smoke

Peace, its going to cost a buck, two ninety-eight to fix. Seriously, as LustForLex pointed out, it is going to take a LOT of info (hopefully not pulled like teeth) to get you any meaningful answers.

You can start analyzing by taking the under-engine cover off, placing a clean sheet of cardboard or newspaper beneath the engine area overnight and letting us know where, precisely on the cardboard, that you notice leakage. If you can locate the general area of the leak and post a picture of the oily engine area, that would help as well.

from what i know it's leaking from several places since there's a few new oil spots every time it's parked and it is burning oil. from the looks of it i think if we were to take it to a shop to get all the leaks fixed, it will probably gonna cost as much as a good used engine. let's just say the entire head/block is covered in oil, grease, and nasty crap from the previous owner not taking care of it.

Just not enough info to make any conclusions. How many miles on engine?

Pull the plugs and might as well do a compression check to see how the cyls are doing. If it is high miles, it is worn, you'll be looking at a rebuild. On a '94 unless the rest of the car is good and you deem it worthwhile to keep it going, I'd say EOL.
