Start the oil pan service by taking out the negative battery terminal and removing the engine oil dipstick. Lift the car, take out the engine oil and get the exhaust pipe and the left engine to transmission strut out. Break the right side engine support bracket cushion thru-bolt by hand, then raise the engine a bit to ease the oil pan back and out. Take out the one-piece gasket and clean the surfaces of the block and the pan gasket, make sure to remove any excess sealant on the rear main cap's oil pan groove, but don't disturb the sealant in the slots. When you see the sealant, trim away any moldings, then wipe out the oil pan with solvent, make sure it's dry with a clean cloth and check the oil screen and pipe for debris. Make sure the oil drain plug and its hole aren't damaged and if the oil pan flange is bent, fix it before going on to the next step. Clean the gasket surface on the block and pan again, trim away any leftover sealant and cut the heads off four of these bolts, then create a slot in the top of each to help them align with the holes on the pan. Put the dowels into the cylinder block, use a tiny amount of Silicone Rubber Adhesive Sealant at the corners of the cap and the block, then slide the gasket over the dowels onto the block. Mount the oil pan above the dowels, on top of the gasket, put the bolts in and tighten them to 24 Nm (215 in. lbs.). Remove all the dowels before fastening the oil pan bolts, tightening all of them to the specified amount. Lower the engine into the support cushion brackets and secure the thru bolt nut with the proper torque, put in the drain plug and tighten it so that it's at 34 Nm (25 ft. lbs.). Set the engine to the transmission strut, install the exhaust, lift the car back up, add oil to the proper amount and place the dipstick.
