mga gurus, ano ba purpose nung hose na nakakabit sa valve cover ng makina going to the air intake tube(between the turbo and air filter)? medyo namamasa kasi ng oil yung connection near sa air intake tube(plastic). nagiging greasy tuloy yung area na yun at yung surrounding nya. the engine is 4jg2(trooper). well, sabi ni gary q. ganun din daw yung dati nyang trooper. is it normal?TIA.
