When should the MAF sensor be cleaned?

naisip ko rin maglagay dati ng oil catch can. kaso every 20k km naman ako plano maglinis, tapos itong ginawa ko kanina 70k km, di pa ganun kahirap linisin. baka ok lang every 50k km.

naka occ pa din yung unit ko pero lately very minimal o wala na naiipon na oil. di ko na nga matandaan last ko nai-drain since wala naman laman. i checked yung outlet hose ng occ at very faint lang yung traces ng oil. so i assumed na yung blow by gas is more in vapor form and less na yung oil.
