so i changed my oil the other day i know the car takes 4 and a half qts but i checked the dipstick it was low i waited 2 days and checked it just now still low added the half qt i had left now its full. so then im like where did the other half qt go i took off the maf sensor to see if there was oil in there nope but the blue o-ring gastket broke off where can i get a new 1? then i noticed i leaked some anitfreeze and it was everywhere. i thought it was that plug leaking but its all on top of the black houseing guess i should replace the whole housing i notice some oil in the house on the valve cover had some oil in it mabe in leaked into the house and down the fileter? the house was melted on to i have to break it off and scrap the rest off. but anyway where can i get a gassket for my maf and should i be woried i lost a half qt of oil?
