Here it is, I bought this car from a family member in 2007. The car had not been used in five years prior to me receiving it. before I drove the car I had a tune up done on it by a mechanic. Spark plugs, wires, oil change, coolant change, new belt, hoses checked, new tires and a new battery. At that time the car had 52,000 miles on it. Now this car has gone through two inspections and regular maintenance with no problems since I had it. Until january of 2009 when I noticed it was overheating and losing a small amount of coolant. Being the paranoid person that I am, I had it to three different mechanics since then. and each one telling me that these engines run hot so its normal to lose a little coolant once and awhile. On May first while I was driving I noticed a little hesitation, So I let the car sit for about three hours, then I checked the oil. When I pulled the dipstick out it was caked in mud. Now I'm now mechanic but I do know that motor oil should not look like that. When I took it to a friend's mechanic my worst fears where confirmed. SLUDGE!! But that wasn't the only problem. He said my heads where bad. At that time I was presented with 2 solutions. 1. Fix the heads (cost of $900) and no promises on how long the car will last. 2. Put a used engine in (cost of $1000) and no promises on how long the car would last. So I asked him what caused the problem in the first place. Now let me tell you about this mechanic first. He did not go to a trade school to learn this stuff. He is a street mechanic in his 60's. And he said the problem was the intake manifold gasket was cracked and it was leaking water into the engine. He also said that it was typical with these type of GM motors. Now why couldn't I have been told that earlier by the other four tech school graduates. Here is my outcome. I made a third option and took that one. 3. Scrap Yard! (cost gained $150) To hell with GM and there associates!
