Oil Pan

Drain engine oil and remove wires from oil level switch (if equipped). Remove power steering pump but do NOT disconnect hoses. Remove alternator and loosen mounting pad bolts enough to allow access to pan bolts. Remove bottom rear bolt of mounting pad and unscrew pan bolts. Turn crankshaft so that No. 6 connecting rod is above crankcase sealing surface and remove pan. On 733i, it may be necessary to detach engine mounts and lift engine slightly to completely remove pan. To install, use new gaskets and apply Atmosit sealer (or equivalent) to all junctions of block, pan and end covers. Continue in reverse order of removal.
