when my car blew the cam seal it leaked all the oil out within about a mile and when i poured oil in some of it ran out the seal. car ran just fine. now when it blew the head gasket it ran like crap and leaked oil. also if i let it sit for a few days then started it. it wouldnt run unless you idled it up a bit for a few mins and black smoke clouded around the rear of the car.

as for the gas sounds like your fuel filler neck is shot.

depending on how many miles are on your car and how old it is. it might be better to junk it as a new fuel filler can run you up a lot of money just for the part itself. and changing the seal or whatever is wrong with the car and be quite costly and isnt something that can be easily replaced unless you are handy with cars so a mechanic would have to do it.
