Why is my truck leaking oil from the bottom?

What causes an oil leak in a Toyota?
Either of these leaks will cause enough oil to flow down the back of the engine or along the parting line between the engine and transmission to collect at the pan gasket surface. Bear in mind that a plugged PCV system can significantly increase the amount of oil that leaks from either of these sources.
Which is the most common oil leak to repair?
It seems that the most common leak to repair is the oil pan gasket when, in reality, the formed-in-place seal on the oil pan seldom leaks. The first evidence that the diagnosis was wrong should be when the block is damp above the pan seal area.
What’s the best way to detect an oil leak?
Leak dye is especially helpful when the type of fluid is easily determined from the color or condition, and the stream is still small enough to clean the suspect area and then trace it with the detection light after a short trip. On especially large or hidden leaks, we’ve had good success with using smoke to locate the source.
What to do if you have an oil leak in your car?
This is also a good method to test the sealing of a freshly rebuilt engine for potential leaks, before complete assembly makes repair much more difficult. This can be done easily with smoke pumped into the PCV system grommet at the valve cover and waiting for any escaping smoke.
