I would take this to an independant shop that specializes in vehicle inspection!!! I think this is about a $200.00 fee. They will go over every square inch of the car and give you a report on all leaks and malfunctions! Tell them your concerns about the head gaskets and have the compression checked. It is quite an impressive list you will receive. Do not take this to the Local Dealer Profit Center. How about the local Vo-Tec school? Just trying to think out of the box on you making a biiigg mistake! Steven.
