GM is not covering engine knock noise on gm crate motor in my 2007 cadillac that still has 1 year left in warranty they are telling me after 2 gm authorised dealships had been insdie the motor and unable to fix the knock noise. that they are not coing the engine and want me to contact who installed is.'

Here is the last reply I wrote after that 

Original installation has nothing to do with this issue as 2 of your GM authorized mechanics have tried to fix the issue without success. at this point Gm certified mechanics at Fairway Chevy in Las Vegas have been inside the top end trying to fix the lifters that they told me were collapsed (did not fix issue).  Then Ed Bozarth said it was the oil pickup down tube seal and when in the bottom end of the motor to replace that ( did not fix the issue). Th internal moving parts of the engine are covered under warranty and have ZERO to do with the current issues, especially since your GM certified mechanics at 2 different dealerships are the only ones that have been internal on this engine not 1 of this GM authorized dealerships said contact company that installed the engine. BECAUSE THE MOTOR IS WARRANTIED FROM GM FOR  3 years or 100,000 miles).
Now if i'm not mistaken Gm parts and labor is warrantied for a year itself. So given this information your are voiding all kinds of factory and GM dealerships Parts & Labor Warranty.
So what you are saying is the motor from GM Crate purchased from a GM authorized dealer with a 3 year 100,000 mile warranty that has a year left in warranty is not covered for the knock it has now. Plain and simple if your tell me that you are not going to cover my GM crate motor with 1 year remaining on this motor at this time. 
I never came to a conclusion. and was not given any explanation of why i woul need to contact the Company that installed the motor. And that is why I filed with the Michigan State Attorney office and the BBB. This motor comes with a 3 year 100,000 mile warranty with 1 year remaining any you are making it sound like will not honor that warranty.
