[QUOTE="C&C, post: 367230, member: 435"] I've got a suspicion that the 31 lb/ft is the factory torque (on a dry assembly). For those that have done their own first oil change, you'll remember that it seemed a gorilla tigthened the drain plug from the factory. After the first oil change though, the pan threads are going to have oil on them and 31 lb/ft is going to be too much, so be warned not to use this value. As far as the crush washer, it is important to know the correct orientation in installing a new one. There is a flat (or more flat side) and a rounder side; the flat side orients toward the oil pan (as this is a machined flat surface) and the rounder side of the washer, which is the crushable side, goes toward the drainplug (crushable to conform to the irregularity of the bolts flat). Once flattened, a very good mating surface is created between the drain plug and the oil pan, and as per the Service Manual, it is only needed to be replaced if damaged. [/QUOTE]
