My rebuilt Engine is leaking from rear Main Seal. I will have to redo it. I used "The Right Stuff" instead of side Seals. Last Time I did this it worked fine. Maybe a problem with Seal Retainer.. I looked at Mummerts Video showing how He does this Seal. He uses clear Silicone to glue the Side Seals to Seal Retainer about 3/4 of the way down the side of Retainer. I can't tell if He also applies Silicone to outside of of the Side Seal. Does He? Is clear Silicone the best choice for this or is Black or even "The Right Stuff" a better choice? I am going to use Side Seals this Time and hope that fixes my Proble. Engine is dry everywhere else.
