(1) Cylinder liner
(2) Filler band
(3) O-ring seals
(4) Spacer plate
(5) Plate gasket
(6) Main bearing cap
(7) Bolt Cylinder liners (1) can be removed for replacement. The top surface of the cylinder block is the seat for the cylinder liner flange. Engine coolant flows around the cylinder liners in order to keep the cylinder liners cool. Filler band (2) and three O-ring seals (3) seal the coolant in the cylinder block.Steel spacer plate (4) is between the cylinder head and the block. Plate gasket (5) is installed between the spacer plate and the cylinder block. The plate and the gasket accommodate the thickness of the cylinder liner flange.Main bearing caps (6) are fastened to the cylinder block with two bolts (7) per cap.

(8) Cylinder head
(9) Spark plug adapter
(10) Water seal
(11) Gasket
(12) Inlet valves
(13) Exhaust valves Gasket (11) on top of the spacer plate seals the engine oil between cylinder head (8) and the spacer plate.Spark plug adapter (9) is located between the four valves for each cylinder. Two inlet valves (12) and two exhaust valves (13) and two are controlled by a camshaft and pushrods. For information on the operation of the valves, refer to Systems Operation, "Valve System Components". Valve guides are pressed into the cylinder heads.Coolant is pumped from the cylinder block into the cylinder head through water seals (10). The water seals are the thickness of the two gaskets and the spacer plate. The coolant exits the cylinder head through water passages into the water cooled exhaust manifold.
