Maliblu,
There are several possible problems when installing a rear main seal. I have made a quick drawing (dont criticize, I did not feel like getting the drafting gear out) that you can view here :

I usually also put a real thin coat of Fel Pro blue sealer (not rtv) where the cap sits on the block near the back.
Also, make sure you get the double lip type seal. Fel Pro makes both types but I think the double lip one gives some extra insurance on older motors where there may be a slight groove in the crank from the old seal. If you need the correct part number let me know and I will get it for you Monday AM.
Last but not least, before you even take it apart, take a mirror and make ABSOLUTELY sure it is not coming from the back of the intake or the distributor and running down into the bell housing. Many a real good mechanics (and myself) have been fooled by this. Look real close. Also make sure it is not the rear oil galey plugs. Hope this helps !
