I have read a couple places and pretty sure I even saw it mentioned here that the 3.1 has a known issue with wrist pins. I'm certain I have even seen the GM piston replcement kit for that issue. It's said that this noise issue has been determined to have NO effect on engine performance or longevity.
Yesterday I took the car to my local Pontiac dealer to ask one of the service writers if the noise in my engine was THAT noise. He looked at me like a deer in headlights and said he had never heard of any issues with the 3.1.
Now I am lost and don't know what to think. Any ideas?
have the same problem?
