3.1L v6 Engine First Step ----- 41 Ft-lbs Second Step ------ Rotate an additional 90-degrees (1/4 turn) and recheck removal and instalation are the same. Start with the bolts in the center and work your way out in a cross or X pattern. be sure to put some type of sealant on the bolt threads.

If your 1990 Lumina has gas in the oil pan, then there could be a stuck injector flooding the engine. There can also be a blown head gasket. Driving the vehicle can destroy the engine.
