similar case happened to my friend. IIRC, civic 2010. naghalo ang tubig sa langis to the point naging gatas na. natunaw ang plastic dipstick. baklas lahat, radiator at engine. May parts din na pinalitan. didn't know what the actual price was but minimum amount might be 30k. home service. nakailang palit din ng oil para siguradong malinis Bago gumamit ng orig Honda oil.
