No. He says that the failed gasket causes drop in crank case vacuum which causes the motor to push oil through the small 1-2 inch long black hose that goes from the head to the air filter on the KAI models. Sure enough, when I took the air filter assemply off, oil was saturated inside this short hose with a few drops dripping out. The mechanic has it diagnosed correctly. Will be putting it all back together this weekend and firing her back up!
