How do you replace the oil pan gasket on a 1993 Buick Regal 3.1 engine?
Drain the engine oil. unbolt the pan and lower it as far as
possible. If the pan is difficult to take completely out, see if
you can reach around it to remove all of the old gasket and sealer.
Carefully slide the new gasket in place, moving it inder the crank
as you work it onto the pan. Add sealant, then rebolt the pan into
place with the proper torque.
