Posted May 22, 201212 yr comment_390851 Okay guys, i'm getting tired and can't think straight-as well as second guessing myself.The rear main seal gets installed with the flat part(face) of the seal facing me or the other way around. I am second guessing myself since I have had two leak. I just installed a speedi sleeve for a new surface on the crank, but now I have somehow got myself confused as which direction the seal faces.God I'm getting old I guess Link to comment https://www.classiczcars.com/forums/topic/43306-rear-main-seal-orientation/ Share on other sites More sharing options...
May 22, 201212 yr comment_390854 Here is front, rear is the same. Just remember "Flat out" or "Show no lip"and you got it "loaded and locked". Link to comment https://www.classiczcars.com/forums/topic/43306-rear-main-seal-orientation/#findComment-390854 Share on other sites More sharing options...

May 22, 201212 yr Author comment_390860 One last thing-should it be flush with the block? Link to comment https://www.classiczcars.com/forums/topic/43306-rear-main-seal-orientation/#findComment-390860 Share on other sites More sharing options...
May 22, 201212 yr comment_390861 Don't forget to oil the lips of the seal.....and yes it should be flush with the block unless you have a previous groove in the crank journal, then it should be say .030 inches from flush to contact a clean surface.

May 22, 201212 yr comment_390862 I have read advice to have the depth so that it does not run where the past lip touched.

May 22, 201212 yr Author comment_390865 Well I'm probably a 1/16" from being flush, which I can't see as being a problem because the hole in cover plate between the engine and tranny is slightly bigger to fit outside the seal. As far as riding a new surface, i installed a Speedi sleeve so the whole surface is new.I got to say I'm a bit anxious about all this---BUT, BUTI do believe I will better off because I do think I installed the last seal BACKWARDS:stupid::stupid:I can't believe I did that, but I will have to fess-up. I will use the excuse that I was under the car last time and under durress--wizz poor I know.
