Brought it to a shop in makati, kay doc diesel forgot the name. Simple test open oil cap and a lot of oil started to explode out. Sufficient na yun so no need of compression test. After which I brought it to my cousin who has a repair shop near grace village. He is the one doing the general overhaul. Saw the engine block and yup inside the piston the chamber is really worn out. I hope this will end my agony. Laki sobra ng gastos.
