GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi there, I am Cam. Can I get your first name?Sorry to hear about your engine failure, that’s a big expensive job. With that, what is your question about this?
Its not common, no. In fact these engines normally last VERY well so to even hear about this is odd. The only indication of oil issues is the pressure gauge and even then, if the pump was coming apart, the debris may have pushed through contaminating the engine but it still had oil pressure.
