My 1995 Skylark Gran Sport finally gave out. It had 156,000 miles on it and all of a sudden the engine decided to freeze-up when I tried to start it. I have no idea why. The engine ran great for months. No chirping, noise or hesitation.
The mechanic said that he worked with all of the Buick engines for these years (1992 to 1998) and said the 3.1 V6 and 3.4 V6 engines have a problem with water leaking into the engine somehow (I don't recall exactly how he phrased it) and eventually the engine will freeze-up. He said the best Buick engines are the 3800's. They're "bulletproof". Now I find out....
I had this car for 19 years and took care of it.
