Yes, Another Rear Main Seal Thread
I got tired of searching and finding different answers, so please bare with me.
My new seal came in the mail today, the "revised" version. Do I need to buy a new backing plate?
And should the seal be lubed before installing?
I've been reading answers that swing both ways, so please post up if you are 100% sure. Thanks!
