If you didn't put it back together yet, I would remove the timing cover and reapply two thick beads. I used the Black RTV for mine.

But not so much that it squeezes into the oil pan. I've torn down a few blown engines with RTV turds stuck to the oil pump pickup from where guys went a little too crazy w/ the stuff.

They normally leak on the sides of the cover, where it meets the oil pan and the engine block. Seal that area real good and put a bead across the botom and you should be good, done this a number of times. Use the blue silicone, and take it apart and do it right IMO. Also, remember to line up the crank oil seal and tighten the front timing cover bolts, then the bottom or that will leak as well. If you have to gob silicone in there, you didn't do something right!

All I did was put a small bead of black RTV in each corner where the oil pan meets the bottom of the block, and I did use the GM cover alighment tool.
No leaks anywhere!

when i did my H/C i l put RTV on the corners of the timing chain cover,no leaks there.but i have a leak at the rear off the oil pan where it meets the block. i had to loosen all the oil pan bolts to drop the pan enough to access the pick-up tube,i guess i should have put some there as well. 
anyone else have that problem?hopefully i can drop it and put some sealer at the corners and fix it.
