CYLINDER BLOCK CONSTRUCTION [LF]
E5U011010300N01
• The cylinder block is made of aluminum alloy, which is cast with the cast iron liner, improving heat radiation and
decreasing weight.
• The cylinder block is a deep skirt type and forms the ladder frame structure with the integrated main bearing
cap. The water jacket of the cylinder block is a closed deck type. Its higher rigidity reduces vibration and noise.
• The cylinder block has the oil separator cover on the opposite side of the fresh air intake, the PCV (positive
crankcase ventilation) valve is installed in the oil separator. Together they function to improve blow-by gas
ventilation efficiency.
• There is no positioning tab where the upper and lower main bearings are installed.
• The main bearing cap bolts are torque-to-yield type and cannot be reused.
• The service hole for installing the SST, which is
used for detecting the No.1 cylinder TDC position,
is located at the right side of the cylinder block.
The TDC position can be detected when the SST
edge touches the cutting surface of the No.1
counter weight.
