My sister bought and has been driving my old 1994 3.8L for over a year. Well the head gaskets blew, and other things went wrong, needless to say its going to be about 1500 dollars in work. I was wondering if it would be better just to replace the engine with another 3.8L, since the car has over 160k miles. Cost is definately a concern, as my sister is working on a VERY tight budget. Maybe someone with experience can help me out.
