Agreed.... of the couple rear main seal leak issues I’ve had, from what I’ve found are two issues. Most seals are sh@t, and the side seals push the retainer off center(well, if the retainers are machined properly)! I will only use the orange felpro seals and RTV on the sides of the retainer only. This procedure has cured both of my leaks and they are still dry.... I did index the seal at 6-12 on the 383, however on the Hemi I put them as designed at 3-9. Both ways worked so.... you be the judge which works better!
