The first thing you should do is check and replace your positive crankcase ventilation (PCV) valve if it's plugged, and make sure your engine oil level is not over full. Both of these conditions can cause your rear seal to leak. Check these and correct them, then see if the leak continues. If not, then you're good to go. If it still leaks, see below.
AnswerReplace rear main seal. Transmission must be removed.
I have replaced the rear main seal on pre-1987 small block chevy's without removing the trans. Not sure if it would work on other engines. Pull the oil pan and the rear cap. You may need to loosen the other main caps to take the pressure off the seal. Use a piece of thin wire to push the upper-half seal far enough to one side to get ahold of it and pull it out. Push the new seal into position, replace the other half in the cap and reassemble.

Where can oil leak on 1994 gmc 1500 350 v8 engine. my truck leaks oil from top rear part of motor but cant find the leak. i know its somewhere near distributor arm?
It can leak oil out from the rear of the intake manifold gasket. The oil sending unit is right behind the distributor and it can leak oil too. There is also a gasket that fits on the bottom of the distributor where it goes into the intake that can leak. And the worse thing it could be is the rear main gasket leaking oil and you would have to remove the transmission to repair that.

Well the rear main seal is at the rear of the engine and would leak engine oil if it was leaking,but if the rear main seal is the leak? it usually requires the removal of the transmisson. But if you know that it is transmission fluid then I would check the transmission cooler lines, transmission cooler, and transmission pan gasket for leaks.
