Leaking brown fluid under the engine

Welcome to 2CarPros.

What you described is oil. However, my concern is why the oil level is high in the engine. When you check the oil, does it have a fuel smell? Is there any evidence of a tan creamy substance in the oil?

If there is a fuel smell, we may have a problem with fuel pressure or a leaking injector. However, if you see a tan creamy substance, it may be coolant mixing with the oil as a result of a bad head gasket. Is there any white smoke from the exhaust?

Take a look through these links and let me know if anything seems to mirror what you are experiencing other than the oil leak.

Also, when you check the oil, smell the oil on the stuck to see if it smells like gas.

Let me know.

Take care,
