Coolant Loss !!!!

[joe k]

Don, Thanks for the procedure, I am going to get with a third party mechanic ( I do not have the bore scope) to see how soon we can pull this off. Seems like a damn good direction to head with this as another point of verification / elimination!
I am also going to try to get a decent picture of the plug for this string. Have been told that if I can direct the GM tech to the exact source of problem (pictures, ect) I may have a leg to stand on.
Once again, thanks for the help.
