Engine Oil Seeping from Rear Main Seal

[Mitevo7]

Cannot find actual start point then need to clean up and check from there.....

The leak came from above oil cooler. I do not know what is that black box. Is it a crank case breather ?

Do you mean this? It's the heater control valve

Here is the more precise one, i spotted the place is most filthy, and the leaked oil travelled down to oil cooler and oil sump below.

I think that might be the oil trap/separator. You might want to check the hose leading into it first. Looks difficult to access

So based on Mitevo's feedback it might just be this black thing which Parakey has identified as the oil separator. Anything this plasticky sure will have a o-ring which will probably fail.

Looks like have to work by feel if dont want to remove the intake manifold.

Yes this is the one we saw its probably leaking oil, even the pipe is filthy. Lets hope for the best, anyhow still need to take off the intake manifold to gain access.

Its too tight, if don’t want to lose engine oil i think its best to remove the intake manifold rather than engine oil cooler to gain access.

Will be very difficult to access. Starter & TB seems to be in the way too. Do let us know how it went

Or if it's just a minor leak, why not leave it as it is for the moment?

Hi, if could i would like my car bone dry with no leaking at all. Furthermore if its an easy fix better take care of it before the oil clogged up the other area where it shouldn't be. Furthermore, we can't be 100% sure its the oil separator part that is causing the leakage, since i am determined to dismantle it to check for it, might as well as 100% sure of the issue and get rid of it.
