340 Rear Main Seal Replacement

Yes, that Fel-pro # does. The half that goes in the main cap. I cut that tab off that is supposed to go out under the pan, thin smear of silicone from the main seal out to the edge of the main cap. When you have the main cap in and torqued, fill in that main cap edge where it hits the block. Those two sides and same for the timing cover corners, silicone.
