I have a oil leak on my Camry. Now one mechanic told me it was the rear oil seal and then another mechanic told me it isn't the seal, its the oil pan gasket. How can I tell if its the oil seal or the pan gasket?

MasterIts hard to tell where an oil leak is coming from with out starting off with a clean engine. Oil will leak downward (gravity) and rearward (turbulence and airflow in the engine compartment when driving) Ensure the valve cover gasket and distributor O-ring are not leaking, if so the top of the engine would be wet. Ensure the PCV valve is operating correctly a clogged PCV valve will cause crank case pressure in the engine to force oil out through seals and gaskets. With a clean engine a florescent dye can be added to the engine oil, the car is driven a short distance, put up on a rack so the underside of the car can be examined, the dye in the oil will turn a florescent green or bright yellow when view with a black light pin pointing the exact source of the leak. A rear crankshaft main seal will show oil leaking at the lower joint between the bell housing and the engine block and will flow rearward gathering on the oil pan gasket.
