Mechanic special. The timing chain has gone out. I see no damage to the block. If you can do the work it's well worth it. It should still last for years. It has been a great vehicle with no issues. It has had regular oil changes every 6 months or 5000 miles. Everything still works! The AC, all the power locks and windows, all the lights inside and out. New battery in 2025 and the transmission was rebuilt at 200,000 miles!
