    My engine light came on 4 days prior. Took to repair shop and code showed PO OB6. I was informed there is a small pinhole leak of antifreeze by the Head Gasket at the block. There is only 63k mileage on this vehicle and if I had blown this gasket I could have put me at risk or others had this blown a gasket. I just cant believe this is happening since there is not much mileage on this vehicle. Please research.
