What could cause a Camry 92 to leak oil?

Where would it come out from because it's not leaking through the drain plug, loose bolt, nuts or old seal etc? If something else is the cause, what can it possibly be and would it be an expensive and difficult job? What parts are most commonly bought for a leaking problem like this plus price and labor individually? Thank you very much.What could cause a Camry 92 to leak oil?
Easiest and cheapest way to find an oil leak: Most auto parts stores sell a dye to put into the system that mixes with the oil and will show up under ultraviolet light.


A treatment usually costs about $4.00 and any ';self respecting'; shop will usually check it out for next to nothing.





The fix is what will cost you. Anywhere oil goes, it can leak. Is it a pressure leak, a gravity leak, a flow leak, etc.





Some repairs, such as a gasket are fairly inexpensive to repair. Even a pressure leak from a filter or a guage sensor are not too bad, but if it is a rear main seal, then the transmission needs to be pulled out, which could be quite costly.





Without proper diagnosis, there is no way to tell where or how much it will cost.What could cause a Camry 92 to leak oil?
Do you seem to have a puddle under the car when it's parked? Or are you having to add oil more often than usual?





If I was getting a puddle under my car, I would go to a self serve car wash and, while the motor was running, spray the oil off the lower part of the engine. Then drive it for a short while and then look the engine over to see where it was wet. This would give me a good hint what was leaking. Once I know that I would take it to a trusted mechanic and have him fix it.
Oil can leak out from pretty much anywhere. Lots of times it can be the valve cover gasket, oil pan gasket, or front/rear main seals.





valve cover or oil pan gaskets are easy to replace. Front main and especially rear mains cost more.
