My TR4 wasn't quite that bad but was oozing oil from every possible pore.
In the end I added a TR3 crankcase breather to relieve the pressure and
that greatly reduced leakage.

The crankcase ventilation provision on a TR4 is (I think) even more
constricted than the PVC on a 4A so the breather seem a prudent relief for
what was (IMO) an inadequate design.

As for the 'why' of your problem -- are you sure the rings got seated?
I'll ask (cause I do not really know) would rings that hadn't seated
reliably show up as low compression?
