you might have to tighten the drain plug on your drain pan if this has not happend b4HELP i think my car has a oil leak what am i looking at in repair cost?
First of all dont start or drive the car with no oil - that will be a big repair bill. Fill the car with oil again and see where it is leeking.
take off the oil filter and see if the old oil filter o-ring is on there if thare is 2 that the bad put a new filter on and make shore there is not the o-rind on the block if so pull it off the you leak plus put the rigth oil in
Depends on where the leak is from. Sometimes its the gasket from the oil-pan--that'll take between $45-$75. Anywhere else it might be a bigger deal but hope it something is simple. But remember, oil is the lifeblood of your engine, if you don't fix it, you'll end up destroying the engine permanently very-very quickly.
