I'm sure you old time Corvette owners know about this web site but I just discovered it. A web site for General Motors Techs. Interesting basic information about the C7 and what the dealership should do or not do for a C7 problem.
1. They talk about the chatter noise the tires make (normal).
2. Driveline alignment
3. Correct oil filter
4. Cooling rings
5. Engine oil/dry sump noise on startup (normal)
6. Z51 clicking/rattle when brakes are applied (normal).
7. Tire pressure monitor
A lot of good info. See following web site:
