i really didn't want to buy a new one, so as long as yours doesn't leak a crack in the mounting hole is OK with me. my car is a 1987 V6 , so i need one for a v6 i guess.
I will leak check it and send you a picture of what I mean when I say it has a crack when I get home. the person that had the car before me made a new hole and screwed it into the car
