Oil pan gasket leak after oil change?
Changed oil myself on the Pajero and now a slow drip from the oil pan seam. Tightened bolts but still seeps. Pan gasket failed or did I overtighten and crack something? Planning to drop the pan- any advice on gasket choice?

Sometimes old cork/rubber gaskets get disturbed during drain/refill and start weeping, especially if bolts weren't torqued evenly before. Overtightening can warp the pan or crush the gasket too. Dropping the pan to replace is the proper fix- clean flange perfectly, use quality gasket or RTV (depending on type). I resealed mine after a similar leak; chose a formed rubber/steel gasket from https://elartcom.eu/categories/engine-gaskets-and-seals-90 - they have oil pan sets for Mitsubishi with good sealing beads. Torqued in crisscross pattern to spec, no more drips even after off-road use. Holds oil pressure fine. Check if they have your engine variant- saves guessing on thickness or shape.
