1991 Pontiac Lemans mileage: 150,000. I recently had a car repair done. The timing chain had broken and the repairman went to test-drive the car after fixing the timing chain. The oil light had come on, the mechanic drove it without checking the oil, and the engine froze up after that. It now needs a new engine. I need to know if it was an error on the mechanics part. Is there anyone else that can advise me on what to do?

Your engine probably had a timing gear that had a gear with a heavy plastic coating on it. When the timing chain failed, it stripped all the plastic off the gear. The plastic pieces end up in the oil pan and clogged the oil pick-up. In situations like yours, the oil pan should have been removed and the broken plastic pieces cleaned out before the engine was started.
