Lubricating Oil Pan
A front sump (1), rear sump (2), or center sump (3) lubri-
cating oil pan option can be used depending on the ap-
plication. The mounting of the lubricating oil pick up tube
will vary with the lubricating oil pan used.
High-Lubricating Oil Pressure
High oil pressure usually occurs after the engine is first
started in cold weather. Cold start oil pressure typically will
be approximately 552 to 689 kPa [80 to 100 psi]. If the
pressure regulator plunger is operating properly, the oil
pressure should drop back to approximately of 449 kPa [65
psi] when normal operating temperature is reached.
