Some of you might recall my paean, last August, to the 1992 Mercury Grand Marquis that has served me so faithfully over the years. As was, in retrospect, inevitable, it didn't take long before that same Grand Marquis chose to test my own faith, making me an unwilling player in the age-old game of Repair-or-Abandon.
All was well until a month or so ago, when I dropped the GM off at the shop for an oil change and tire rotation. About an hour later, I got a call from the service manager. They would, he reported, be unable to change the oil because the oil pan was so badly rusted that attempting to unscrew the drain plug would lead to a full-on disaster. In fact, oil was beginning to seep through the metal. Then he gave me the bad news: the oil pan was spanned by an immovable chassis crossmember and various other components. Replacing the pan would require them to lift the engine high enough to allow it to be slipped past the offending hardware. The cost, including parts, labor, and tax would be in the $700 range. Then, just by way of truly testing my resolve, he added that the car needed a water pump and serpentine belt.
The cost of these repairs approached the market value of the car, which meant that I had to do some serious thinking. The obvious alternatives were to a) dump a grand into the Grand Marquis, or 2) cut my losses and walk away from it. But there turned out to be a third, less obvious option, and to see how I arrived at it you'll need a bit more background. You see, a couple of years ago I noticed that the Check Engine light would come on for a brief period soon after I hit the gas hard, say to pass someone quickly on a two-lane. My local shop ran a scan, and found "two fuel lean codes, one EGR code, and a pass. system code." (Uh-oh!) They estimated that the needed repairs would run somewhere in the $4-600, depending on what was found when various components were examined more closely. The estimate also included the news that "none of the codes at this time will make the vehicle unsafe to drive." (Aah!) Thus reassured, I declined the repairs and opted instead to place a square of electrical tape over the offending light.
