I think ive got a big problem. I rebuilt my engine a few months ago and finished the break in period. I noticed a few days ago that there is a really small engine oil leak coming from between the tranny and the engine (i guess the rear main seal?). I wiped it down and re-checked it today and there is a little more oil there. What do yall think?
 
Ok, so basically im not hurting the engine running it the way it is, right? And to replace it i would have to remove the starter, steering linkage, oil pan. then replace the seal? is that it?
 
your biggest issue will be the leak oiling down your clutch (if its a manual trans).

you have to drop the pan and crossmember for starters, remove the rear cap, and use needlenose pliers to tease the seal out....its a dexterity exercise more than anything, esp with the trans in the way. Best performed on a lift *grin*

Be sure you offset the seal from the rear cap, and use a dab of sealant at the corners of the seal (as shown in Tom Monroe's book).
 
Sounds like rear main. But before you start taking things apart check the following as they can trail into the bell housing. Rear of the valve covers, between the heads & block, rear of the intake manifold & pan gasket.
