Nwebie here. just bought a corolla gl 1.6 ae92 90 mdl from a friend. when i showed it to another friend he opened the engine oil cap while the engine is running and pressed his palm over the oil inlet mouth to test daw if the engine is still good. sad to say, droplets of oil manifested in his palm and he said the engine is having a "blow by" at hindi na daw magtatagal. how is this true mga guru eh maganda at pino pa naman manakbo ang oto. dapat daw hindo tumatalsik ang langis pag binuksan ang bibig ng makina....request advice here. thank you sirs...
