Read seal leak on 420 SEL
 

I pulled my engine back out to fix a rear seal leak and found I'd rolled the seal when I installed it. I reinstalled it and made sure the cover was well sealed and the crank seal hadn't rolled. The oil leak was cut to about a third, but didn't stop. What should I look for the next time? Should I order a first repair seal? I'd like to only pull this engine one more time. Four is enough. Thanks.
