When putting the timing cover on should the alignment at the bottom with the block matter or the alignment with the balancer?   I took my car out for a drive today and 
oil everywhere.  I didn't see any dripping on the seal but there was some on the gasket for the 
oil pan.  I dropped the pan and there was 
oil between the gasket and the block. Also there is about an 1/8" ledge off of the block to the timing cover.  Should that get filled with RTV?
