A guy I know has a G8 and took it it to a “GM guy” who claims his motor is probably shot. I haven’t seen the car, but the things he’s been told by this guy raise a few eyebrows. Enough so that I suggested he get a 2nd opinion. For example; the tech needs “6 special tools” to remove the harmonic balancer which appears to be wobbling and may have “ruined the engine.” And the tech doesn’t want to buy them just to work on this specific car.
Anyone have any recommendations? @LZ1
