Warning: I keep seeing guys skip the torque wrench on aluminum oil pans
I watched three different techs in our shop this month just zip on aluminum oil pans with an impact gun. That's a fast way to warp the sealing surface or strip the threads. The spec on a common 2.4L Honda pan is only 9 foot pounds, which is way less than you think. I started checking used pans we pulled, and about half have slight warping from over-tightening. It only takes an extra minute to do it right. Has anyone else noticed this becoming a common habit?

Honestly, that spec is so low it's basically finger tight. A quick bump with an impact on low setting seats it just fine, never had one leak. You're way more likely to get a leak from under-torquing and forgetting to check it.
