I have a 1987 S10 ExCab 4x4 that I purchased new and maintained well since new, keeping it mostly garaged. Recently I had the infamous problem with the 2.8l getting coolant in the oil, in my case with 82,000 miles. At this point I do not know what the bill will be, and do not expect anything from GM for something this old, but find it curious how many people report the same problem with the 2.8l and its follow on 3.1l and 3.4l.
I started buying Toyotas under the Chevrolet and Geo nameplate, and have started buying brandname Toyotas as of a few years ago. Toyota apparantly had a sludging problem with some styles of engine, one which I have but haven't had the problem, and have come out and sponsored an extended warranty program for its customers. I have found no such GM program for the coolant leak flaw. It appears my decision to move away from GM products was a good one.
