To change the oil pan gasket, remove the oil pan and replace the gasket and then put the pan back on.
carefully! Let engine cool a bit if driven, not too much as warm oil will drain better. Drain oil, remove oil filter, loosen oil filler cap on engine, Loosen all the bolts around the pan. Remove pan, gently scrape off old cork like gasket with a thin metal putty knife, DO NOT SCRATCH SURFACE!!! Go gently and slowly. Put new gasket on pan, install pan with gasket, tighten bolts (do not strip), install new oil filter, refill with new oil, check oil level on flat surface, add as needed. DO NOT OVER FILL! Start engine, and check for leaks.
