Large oil leak in the rear of the engine.

Greetings to all, I am new in the forum. I hope you can help me.

I have a 2013 D4 SDV4. After changing the right valve cover (For the common problem of breaking). It started with a large oil leak in the rear engine. It comes from above the bellhousing and descends on BOTH sides of it.
I add them after changing the valve cover, the engine stayed started in idle for a long time (about 45 minutes) accelerating it and maintaining it several times at 2000-2500 rpm and no oil leaked. The leak was seen until after he walked on the street in a very short distance.
The valve cover gasket was checked and it is well installed and there is no oil leakage.
Thanks for any help.

Is it oil or could it be the oily mess that escapes if the air intakes are not properly connected? Look at the connection above the fan. .

Thanks for answering.
All air intakes are checked, and the connection above the fan. Unfortunately everything is ok. Embarassed
For it to run on BOTH sides of the bellhousing, it has to come from the V (between the two heads) where the high pressure pump, the oil separator and the oil filter / cooler are.

Maybe the oilseal on the back of the motor, between motor and gearbox?

Ah, sorry I do no see the oil is from above bellhousing...

Common fault where the oil cooler fails/leaks and oil fills the v and rolls out the back. You will need to replace the oil cooler/filter housing and seals between the cooler and the block. It's not a simple job by any means so if you're not experienced in DIY, I suggest paying someone to resolve it.
