Oil leak vs "misting"

Currently have the engine out, and I am putting together a parts order. Car needs a few thing in addition to the normal stuff, (motor mounts, water pump etc).
I currently have the lower timing gears bearings (170787) as well as the front and rear main seals in my cart and i wanted to run this by the forum before i pulled the trigger.

My car has never left a single drop of any fluid on the ground. The pan, has no evidence of even the slightest bit of seepage.
There is however, what I would say nearly every car with mileage on it has on it, 'oil mist' or oil residue covered in a little dirt behind the lower timing gears, and what looks to me the seam between the motor and trans.
The car has 43,000 miles on it and I really have no way of know if the engine has ever been washed on previous majors (doubt it)
I am not trying to take shortcuts, I guess what I am saying is, based on reading many posts here i dont think ferrari is particularly known for their seals, would replacing a seal that is not dripping be not only a waste of time, but possible open a can of worms? I say that, because i would have to remove the pan, the front and rear cover and to install new seals that may 'mist' just like the old ones (or worse lol)


Thanks for the input guys

 

To Clarify, two separate areas of oil residue. One is around the front lower timing gears. The other is at the seam of the trans and motor. That's why I think it might need a rear main seal.

 

I ended up just buying everything anyway. Little more work, but i'll get to take some cool pictures of the motor i guess lol
Here is the bottom of the pan on the left, and the trans on the right

Not "leaking" there is what i can only describe as oil misting, seepage or residue.

Thanks for the comments guys.
I guess I don't need an oil pan so-clean-you-could-eat-off-it, however i dont want a engine that drips, nor one that is all caked up with grime like an 80s truck.
Again, my car has over 40k miles, never a single drip in my 3 years of owning the it and in my experience the grime is maybe only a tad more than is should for almost 20 years of driving.

The car had 2 majors done by ferrari of altanta, and one done by a ferrari shop in south florida, no mention of these seals being done on the history.



The only thing I am convinced off right now is, I want to absolutely "do it right". Maybe its the pride, or the aircraft mechanic in me.
The parts are already on their way so I have them if i need them. It would be very easy to give it a good cleaning and wait till the next major the address them, I guess it might help avoid unnecessary repairs.
I took some more detailed pictures that hopefully illustrate why i thought it might be prudent to do this time around. The flash really over-emphasizes the grime, and the front is only wet for the coolant hoses leaking from the engine out.

Thanks,
I suppose if i do decide to skip on the rear main and worst case it starts leaking like crazy, my labor rate is $0 lol. The engine out was actually much easier than expected.
