Hi guys. I just recently bought a new Kawasaki 14 hp 420 for my wb and the oil has been over flowing the crank case, leaking out by the oil filter and cause the machine to run crappy. I check the owner's manual for oil quantity and it says 1.4 qrts. I am putting in 1 qrt when I don't take off the filter. I check the dip stick and it appears alright. My older kawasaki does fine with 1 qrt. I don't want to be low on oil but one qrt seems to give me problems. Have any of you guys had this problem?
