Exclamation 2GR-FE (3.5L, V6) engine rear main seal leak/seep

Hi everyone,

I just purchased a 2014 Lexus RX 350 from CarMax (100k mi, $20k). Inspection reveals a very mild rear engine seal leak/seep, as the photo shows here. (Fortunately, the front timing cover showed no sign of leak).


I consulted the Lexus dealership and an independent mechanic about the oil seep at the rear engine seal, they both recommend keeping an eye on it but no action for now.

My questions are:
How common is the rear engine seal leak?
Would this be as bad as the front timing cover leak?
I got a 10-day return from CarMax, should I return this one and keep looking for a better one?
The 3rd-gen RX 350 is my favourite car, and I love its white exterior and tan interior. I just can not decide whether to keep or return this car. With this market, it is really hard to find the right condition at the right price. I'm not in desperate need of it, but it seems too difficult to find a good one in this market.
Thank you so much!

If the vehicle I own develops the same symptoms [and diagnosis], I would keep an eye... just as suggested by the mechanics.

On the other hand If I was about to purchase a vehicle with the condition, I would ask the cost of repair and then estimate the purchase price of similar vehicle with no known defect/condition [make sure the seller has not discounted for the fact]. Once those two numbers are established, I will ask for adjustment in price knowing fully well that the seller may not agree to the full difference. I would also establish a number in my mind that I should not offer higher than a certain based on my level of liking/need/features/maintenance-history etc. Do keep in mind that RX being the most popular model, there will be plenty to choose from, and it is just a matter of price.
