Crankcase pressure

Most likely the springs were installed due to the hose bends being too tight. I don't think the report says the lines blocked, just too high crank case pressure, probably still due to bends being too tight and springs taking up the small space inside the hoses. 

I followed the installation manual and checked all of that including the suction side and all was fine, however the suction side has higher vacuum but still within spec when the oil is colder than 40 degrees C. That knowledge has caused me too operate the engine more gently until warm.
