I have a minor leakage which for me looks to be between the engine and the AT. There is a black (inspection?) lid held by two minor bolts. The leakage is on the bottom side, near the bottom bolt. See pics.

Should there be any oil flowing behind this lid? I assume it is engine oil from its consistence. Blackish due to end of oil life syklus.

Thanks, will do.

It is difficult to do good searches as I am not always familiar with the correct mechanical terms.

Jon, there are some case bolts which have also been a source of leaks.. much easier and cheaper to fix than a rear main seal.

Let me see if I can find the thread about that....

Cross my fingers...
I have torqued all the bolts on the exterior, and the only one moving was the lower bolt on the inspection lid.
I'll remove the lid tomorrow and have a look inside.

If it is the main seal, may it be replaced without having to take the engine out?

I believe this thread is the one Speed might be referring to (I just remember "pesky" for this one & it's easy to find LOL.

This would be a thousand percent better if it's your cause (compared to main seal). Good Luck.

Thank you for the tip and the link. But aren't these bolts visible from the outside of the engine? My leak is definitively coming from inside the flywheel lid.

Have folks had any luck managing a rear main seal leak with a high mileage oil like Valvoline MaxLife? I once had a Dodge Dakota with an engine that would drip multiple drops overnight if a regular oil was used, but it slowed to just a wet spot on the oil pan with MaxLife.

Long story but I find this so weird I have to share it with the community:
A friend borrowed my Ridge for hauling his car to a Track Day appx. 250miles drive from my location. Due to the leak, I asked him to pay attention to the oil level.
He returned the car a week later and told me he had to fill up with almost 3 liters of oil on the retour. Even after adding so much oil, it barely showed on the dipstick, he told me.
I found it really weird as there were no oil fumes or any noticeable dripping under the car, but he is a "car guy" so I took it seriously. (In fact, I started the search for a donor vehicle to import from the US...)

Today I finally had the time to do a proper inspection on my car. Way too much oil in the engine, and having a Fumoto valve on the oil drain it was easy to tap out the excess which was over 2.5 liters. No drops hanging under the engine and the area under the flywheel inspection lid is now completely dry.

With so much oil added and towing almost the same weight as the Ridge resulting in very high oil pressure when driving steep uphills, I would expect a major leak in the area of the main seal if it is faulty. But there is nearly no traces of oil underneath the engine anymore.

When I discovered oil leaking the first time, the car was parked in a small downhill with nose downwards. I will have to do a similar parking and see if it has any influence.
