2015 Passat 6mt (35K miles) has developed a leak at the oil pan flange (verified to not be leaking from higher up like cam / crank seal or valve cover. Looks to be a straight forward job but wondering what the recommended sealant is for this job? Learned from the 7.3 powerstroke forum that the sealant type is critical for pan sealing on those and they even recommend removing the engine and inverting for proper sealant and oil pan installation! Hopefully that is not necessary here. Oil leak is small but over time soaks the plastic foam filled pan "skid plate" and eventually even drips from the lower cover.
