    I have PM you twice two days ago?
    I guess this is for par with GM.
    Why bother

    So I sent him a PM two days ago and still no response?
    Why bother.

    Typical of GM.
    All talk no action.
    I've PM this person last week and no answer.

    Well we have the new remanufactured motor installed.
    I spoke with the mechanic at the dealership and asked what exactly happened and if this was normal?
    He told me the rings on the piston were worn and caused the leak by which fouled the plug. The cylinder wall were scarred and the other cylinders were starting to look worn.
    He just shrugged his shoulders when I asked him if this was normal (that kind of says it all right there).
    I know Black Bear Performance offers a tune solution to turn the AFM off. I guess they started to offer this due to the rash of complaints and problems that have been associated with this.
    I have sent letters off to GM's upper management pleading my case. I'm not expecting much but it doesn't hurt to try.

    The OP has copy and pasted the above posts word for word on various Internet Sites. I guess getting a new motor for 50% off isn't good enough. In any mass produced product you are going to have a failure rate. This same motor is in the Silverados/Sierra which GM sells about 40,000 a month of and covers for 100K miles.

    Black Bear offering their services for whatever purposes is pure speculation on your part. As is stating the vast numbers of the motors manufactured the same time as yours will ultimately fail.

    Get over your frustrations and move on.

    So I received a phone call from GM Corporate (my letters got through). I have spoke with him several times and as of now GM is holding firm on the 50/50. They say because I accepted the deal there's nothing else they can do? I reminded him I accepted the deal because I had a useless car and it had to be fixed (holding a gun to my head).
    I told him right up front I'm not looking to get off without paying anything. I understand the car was out of warranty but the fact of the matter is the engine failed under 100K miles.
    He said there were a few more upper management people he could plead my case to. So I don't know if he's blowing smoke up my a** or he's being truthful. We'll see.
