E36 with a leaking rocker cover gasket?

[Jollyno]

 

NOTICE
I am youthful and foolish.
Acquired a 1996 E36 as my inaugural vehicle.
Familiarise yourself with the elements and locations of the primary engine components, and that suffices.
I prefer to repair the vehicle independently rather than entrust it to a mechanic, though I recognise that this may not be prudent; I will resort to a mechanic if required.

Acquired the vehicle a few weeks prior; the seller asserts it had no leaks, was transported 500 miles to my location, began leaking the following day, and exhibited increased leakage after subsequent driving.

The E36 exhibits leaks from multiple locations; refer to the attached video and my grievances during the MOT, which indicated a rocker cover gasket issue. However, since that was three years ago, it could either be a relevant concern or something to disregard, as it may have been repaired or replaced to prevent recurrence.

Small droplets are accumulating along the timing chain cover and across the oil pan, with some forming higher up.

I appreciate your attention, and I kindly request that you refrain from labelling me as foolish, as it is painful.

No video has been uploaded, but searching for information on replacing the E36 rocker cover may provide some visual assistance.

Apologies, the video has been rectified now.
I will attempt to replace the rocker cover gasket regardless, thank you.

The most effective course of action is to power wash the entire engine, both above and below, and subsequently identify the source of the oil leak.
