Applying the incorrect sealant or over-torquing a pan designed for RTV can squeeze the sealant out completely, leaving gaps that allow oil to escape. Typically, this involves tightening the bolts in stages, moving from the center outward in a star pattern.

Using a torque wrench calibrated to the correct specification is non-negotiable; relying on "feel" or impact gun settings alone is a common pathway to over-tightening. Factory Specifications and Variations While the exact number can vary slightly depending on the year and specific application, the general range for most performance and stock oil pans falls between 10 and 15 foot-pounds.
If using a RTV silicone sealant, the pan flange must be allowed to cure fully before the engine is run. Aluminum is softer and more malleable; therefore, it is much easier to overtighten the bolts and stretch the threads.
