NOTE:

When raising or supporting the engine for any reason, do not use a
jack under the oil pan, any sheet metal, or the crankshaft pulley.
Due to the small clearance between the oil pan and the oil pump
screen, jacking against the oil pan may cause the pan to be bent
against the pump screen. This will result in a damaged oil pickup
unit.
