Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Intake gasket failure on my 1998 Pontiac Grand Prix 6 cylinder 191 M 3.1L sfi engine was told by GM because car has over 100,000 miles they may not be able to help. I did some research and GM has a tsb stating that the material used for the gasket was defective if that is the case what does milage have to do with it?
