Oil Filter Housing "FREEZE PLUG" Leak

[cnn]

Has anyone done the E39 O.F. Housing FREEZE Plug Fix?

I have been chasing a minor engine oil leak and just replaced Oil Filter Housing Gasket (The Gasket between the Housing and Engine), but to my surpise, the oil leak from the Oil Filter Housing persists! It is minor, just a few drops on the driveway a day.

After some meticulous cleaning and checking with a mirror/flash light with engine running, it turns out the Oil Leak is from the FREEZE PLUG of the Oil Filter Housing. I know these are not FREEZE Plugs but they look like it (aka Welch Plugs).




So, E39 uses "Welch" Plugs. The previous models: E30, E36 and Z3 used O-rings (PN 11421709513):

Searched around, there have been problems before in different models. This is a thread from E34 (1995 525i) but the idea is the same:
