I have had an oil leak problem for quite some time. The transmission gave out a few months ago and I had the transmission shop go ahead and replace the rear seal. The oil leak was not fixed. So I began to look for another reason why it might be still leaking. The valve covers were leaking so I replaced them. This still didnt solve the problem. I figured maybe it was an oil pan gasket. Sure enough the oil pan was leaking as well. I replaced the pan gasket. But the truck still leaks oil. What could this be? Would it be an intake manifold gasket? When underneath the vehicle the oil drip comes from above where the transmission and the oil pan seat together. If you reach your hand behind the engine (when on top) you can feel a greasy build up from where oil has been leaking. Where could the oil possibly be leaking from?

The engine oil pressure sensor is at top rear of engine check there they can leak when bad. Especially if it leaks fairly well. The pic is as close as I can come to pointing itout where it is.
