1991 Pontiac Lemans Repair Question
1991 Pontiac Lemans oil light on
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.
