I had this happen on my Chevy truck. It was the oil filter. I was lucky I was in the truck. I had started it up in the morning and I looked at the gauge. It read 80 psi then it pegged. Just as I turn it off the filter split. I had just had the oil changed the day before. I called them and they had me towed to their shop. The manager was real mad. He had thought they got all of the bad filters out of their stock. No harm was done and he refunded my money and gave me a form stating that if any damage showed up from this they would cover it. That happened at a round 190,000 miles. I now have over 300,000 miles.
