Hello everyone itsgreat to find this website.
I have a 1997 grand prix GTP. It died at 80 mph on the highway the other day no hauled it to a shop and they told me the camshaft had broken completely in half. The lobes also broke off the journals so the whole engine had been destroyed because of this. They told me that they have had this problem with the 3800 engine before. I have never heard of this.
Is this common on this engine? And could you tell me some possible causes so Incan avoid this ever happening again. Oil has always been changed regularly and I use only synthetic.
