Hi Chappy
I am sorry to see that your ordeal persists.
You may have some good news.
Oil leaks from above the cylinders are either a case through bolt or two (easy to remedy) or possibly leaks around the oil sender, breather or thermostat.
There isn't much else above the cylinder line.
Check those items and who knows, maybe your luck will change.
As for globbing gobs of goo on a freshly built 911 engine: NO NO!! step away from the precision built German vehicle

.
Remember this nightmare? you don't want to join the ranks of the absurd.
