The engine is removed with the removal of the engine, which is done by removing the oil pan, oil pump pickup and baffle, and generally cleaning of the oil pan for new gasket installation. This entails taking out the engine, removing the timing chain cover, and prying off the oil pan at specific points as well as unbolting oil pickup from underneath it taking off #3.The process involves removal of oil filter in addition to installing a new one after tightening all bolts on oil-pan.It's worth noting that this has been made possible through taking away various screws that hold the object firmly to its base and relocating it to another place. The old gasket material is carefully stripped off both the bottom surface of an engine block and top surface of an oil pan by using a lint-free cloth soaked in brake-system cleaner. Any crack or leak on it should also be checked while there must not be any obstruction at its base screen. The bolts that pass through into its bottom from underneath an oil pan should first install a new oil seal onto it before securing it with these bolts. The next thing to do is to install another part called a baffle inside the newly fixed oil-pan and tightly bolted down by eight fasteners; four on each side. Proper alignment can be achieved by creating aligning studs using MB x 1.25 mm bolts placed in assigned holes 1 & 2 for this purpose on this labeled piece of equipment. A thin layer (about 3 mm) of oxygen-sensor-safe RTV sealant should be spread over its upper mating face and at both ends where front and rear covers join an engine block.Consequently,tighten these bolts until they are snug.The aluminum bolt-on part gets attached before installation is finished by replacing old gaskets on top surfaces before tightening them up carefully.Therefore,you should put back in place all screws as their absence may lead to a destruction of the whole structure. To prevent crushing or damaging this component, take the following steps; remove all fasteners and then replace them after the filter has been changed. The remaining installation steps are executed in reverse order before installing a fresh oil filter and adding correct amount and type of oil as well as starting an engine for leaks-checking on it before returning a car into service.

For installation, the oil pan and engine block surfaces must be meticulously cleaned of old gasket material and sealer using a rag soaked in brake system cleaner. The oil pump pickup should be inspected for cracks or leaks, ensuring the screen at its base is unobstructed. A new oil seal should be installed on the oil pump pickup, which is then secured with bolts in the oil pan's bottom. The baffle is installed inside the oil pan, with its retaining bolts tightened.
