Lifting the car and taking off the oil pan In order to take off the oil pan, you should first discharge the battery by detaching the cable from it's negative terminal. Then, next, disconnect the plenum, the intake manifold, the valve covers, and the timing chain cover. Depending on the make of the car remove the engine using a suitable engine support fixture and then remove the front subframe. Now remove the right-side engine mount bracket bolts and the bracket, then the long bolts that hold oil pan to the rear main oil seal housing-some model may be nuts on this. Undo all the remaining bolts that hold the oil pan with the timing cover and engine block apart and pry the oil pan off the engine block in areas noted above that will minimize rustled up pieces of metal. If necessary, you can remove the oil level sensor by rotating it counterclockwise until it comes loose from the oil pan, then undo the retaining bolts of the baffle and take it out also, and the oil pickup oil seal needs to be replaced also. Before installation, clean the surfaces on which the oil pan and engine block will be bolted with brake system cleaner, inspect the oil pump pickup for cracks or leakage and make sure that screen is not blocked or damaged. Replace the oil seal on the oil pickup for the pump, re-torque the bolts in the bottom of the oil pan and fit the baffle. Tap two studs of M8 x 1.25 mm bolts and thread for at least 25 mm while the nut head of the bolts are capped and place the threaded studs on the oil pan bolt holes for the alignment. Use a 1/8-inch wide groove of RTV sealant to the mated surface of the oil pan and to the corners of the timing chain cover and rear main seal housing. Place the oil pan and secure the bolts loosely; also, remove the threaded dowel pins and properly tighten the oil pan bolts with a desired torque sequence. Last of all, put the correct kind and amount of oil, taking action and turning on the engine, then inspect for leakage before returning the car to operation.
