Could someone give me the TSB number or article for the SBC oulsation damper. Also, my oil level check almost always tells me to reduce oil level when I check it, even though my shop has supposedly done this. They say the sensor is extremely sensitive, even the slightest amount will cause it to say reduce. I don't mean the red warning symbol that would come on while driving, just the submenu that can be used when the engine is off. I want this to be working becaus e someone has told me that when he chekced in some secret menu over a quart was missing when the computer didn't say anything! Thanks for the help.
