cylinder base gasket blown - why???

Just had a trip to Germany and Nürburging. Noticed that engine was leaking oil, but was not able to do anything until I got back home.
Engine was never over revved.

Was under the engine today, and it looks like the cylinder base gasket on cylinder #4 is pooped out.
I'm really not sure, but looks like the gasket on this cylinder is more out than on the other cylnders, and the leak looks like coming from this place.

Not any leak when engine is not running, but when running it leaks too much for me to like driving it.

I had a misfire due to coil problem earlier, could this have caused too much pressure in the engine to blow this gasket?

Any suggestions why this has happened?
Engine is newly rebuilt, new head studs and torqued according to spec.

Seems like I have to take out the engine again to verify and fix
