Crankcase pressuring.

Hopefully someone has in depth knowledge of the CRLB engine.

The problem is oil leaking around the injector seals. Is being pushed through the seals under pressure and onto the top of the camera cover. It seems to me the crankcase is pressuring and forcing oil past the seals in the cam cover. The breather system is rather baffling, with what looks like a breather built into the cam cover. We are asking if any internal breathers can be cleaned or does it require a replacement camera cover. This might sound a bit amateur, but my mechanic is very experienced and he suggested there could be someone here with a better understanding of the system than us.

Thanking you all on advance for your time.
