excessive crankcase pressure

[Vikingbisset]

Just wondering if anyone has had a problem with the front rocker cover gasket blowing out.there didnt seem to be anything abnormal until it popped out and the motor quit. It restarts but im thinking i may have to do major surgery if its not a plugged breather hose.Any ideas?

Assuming the breather is clear the I would start by doing a cylinder leakage test of if not possible a compression test.
