rear Main Seal noobie question

Just to emphasize something TB mentions,, about the RTV at the red lines,, just a very thin film if any,, some folks think if a "little" is good,, then "more" is better..

I don't use any,, my concern is too much rtv would open the tolerance of the main bearing,, but more important is the main oil gallery from the pump passes thru that joint,, and any clearance created by RTV may cause oil pressure to blast outta there ,, causing other probs..

Check mating surfaces for any imperfections..

hope it helps..
