Toyota Repair: 92 cellica oil leak, crankshaft seal, 4 quarts

Question
I have an oil leak on the front of the engine i think at the bottom leftside only when it is running it will leak. i started it up after it was not running for over a month. there was no oil under it. after running for 6 minutes i looked under the car and saw oil dropping. it has 230000 mile and still runs great i cant see the leak but know it is bad. 4 quarts every 150 miles

Answer
Most likely the front crankshaft seal, I recommend removing the timing cover for inspection, it may also need the camshaft seal and the oil pump seals and the timing belt should be replaced at that time and it's agood idea to also replace the water pump and the drive belts.
