If it's letting go at high RPM and spilling oil onto a hot exhaust they will be in serious trouble with this engine.
Lets hope it is a minor issue.
There is a lot of rule volatility in GT racing at the moment - Porsche are sticking with the old engine (which remains homologated for a good few years yet) as they are waiting to see what the best way to go is before committing to an expensive development programme. It is not impossible that the racing cars may have to go to Turbos, and this explains why they are distancing from the GT3 label on the racing cars. Other than the 991 GT3 Cup cars, the 991 is just a 911 RSR and 911 GT America in the current line up...
As for the road 991 GT3s self immolating - the version that I have seen so far is that it is a very minor problem with a straightforward retrofit in the oil system (think badly designed bracket - the fires so far have not been failures of the engine itself but rather ancillary. I hope that turns out to be the true story and if so is not going to be a major concern to owners).
