Permanent VCG solution M54?

[Bmwe5320023.0]

Hey guys, with 3 bmws it's so hard chasing around common problems, trying to fix everything up, and before you have time to fix the second thing, first one breaks again lol.
I've already replaced VCG with oem gaskets, and that wasn't that long time ago, not more than 30km.

Is there any permanent solution?
I've read some upgraded to M56 valve covers, but it still leaks. I've seen aluminum valve covers on amazon/ebay, but not sure how good they are. At about $400 CAD, I don't want to buy junk.

Had anyone replaced the VCG completely with RTV lol?
I'm just looking to see how to do it once and for all, or for at least 10 years, like other gasket that last a long time...
