Yun Toyota Altis 2003 model 1.6G (automatic) ko po, medyo mga 2 years bago nachange oil, pero sobrang konti ng gamit ko po in those 2 years. Nagkaroon na sya ng namumuong langis sa cover kapag binuksan, sabi ng mechanic hindi na sya makukuha sa flushing. After ng change oil 3 months ago, nabawasan po ng malaki yun langis based doon sa dipstick. Tumatakbo pa po yun sasakyan pero napapansin ko po kapag umaga, kapag malamig ang makina, start ko, medyo maingay yun engine, yun ugong malakas. Kapag nagdrdrive naman po ako, may konting ugong din yun parang tunog ng airplane, medyo mahina lang. Aside from that, wala naman ako ibang napapansin na problem. And also yun oil indicator light hindi po umiilaw kahit na low in oil na po ako.

I asked for the opinion of a friend who knows something about car, and he is recommending me to have the engine undergo a general overhaul para malinis po yun loob ng engine at mapalitan na yun mga nasunog/nasira na parts. Ano pong massuggest nyo sa akin? Kailangan ko na po ba ipa overhaul? Can u guys recommend a shop/talyer who have this service and more or less magkano po ang magagastos ko?

My friend found a shop which offers minimum of 25k for overhaul service, and depende daw ano papalitan sa loob kapag binuksan lang daw bago malalaman, possible na umabot daw ng 50k if madami papalitan. Do you guys think a general overhaul is the solution to my engine problem? And will my engine lasts after the overhaul? How about buying a surplus engine and pachange engine na lang po? I heard medyo mahal at madaming proceso sa pagpalit ng engine, kailangan din po ng bayad sa pagpalit ng engine number sa LTO. Thanks.
