Among Honda's engines, the B16 is the most common, showing up in its most popular vehicles such as the CRX, Integra and Civic. The B16A was used in the Honda Civic and a number of other vehicles in 1998. That year, with its 9.4-to-1 compression ratio, the engine produced 106 horsepower at 6,200 rpm and 103 foot-pounds of torque at 4,600 rpm. Like all manufacturers, Honda establishes specifications for its engine components to ensure that all of the requisite parts attach properly.
Honda's B-series engine family has progressed through a number of generations and stylings. The B16, for example, has at least eight variants: B16A, B16B and B16A1 through B16A6. The most common, the B16A and its sub-styles, have been available since 1988 in vehicles such as the Honda Integra and Honda Civic. The torque specifications are identical for all versions of the B16 engine.
In the B16 engine, the cylinder head bolts to the engine block first with 22 foot-pounds of torque and then with 62 foot-pounds of torque. The 6 mm camshaft bolts require 7 foot-pounds and the 8 mm bolts require 20 foot-pounds of torque to join with the cylinder head. The exhaust manifold and cylinder head attach with 23 foot-pounds of torque. The intake manifold requires 17 foot-pounds of torque to bolt to the cylinder head.
The oil pressure sensor and cylinder head join with 13 foot-pounds of torque. The valve-cover-to-cylinder-head bolts receive 7.5 foot-pounds of torque, and the variable timing solenoid requires 8.5 foot-pounds of torque to bolt properly to the head.
The crankshaft in this 1.6-liter engine bolts to the engine block in two steps -- first to 18 foot-pounds and then to 56 foot-pounds of torque. The connecting rod and crank attach first with 14 foot-pounds of torque, then with 30 foot-pounds. The flexplate, also known as the driveplate, requires 54 foot-pounds of torque to bolt to the crankshaft. The flywheel-to-crankshaft bolts receive 76 foot-pounds of torque. The pulley and crankshaft join with 130 foot-pounds of torque.
In the B16A engine, the oil pan bolts to the block with 8.5 foot-pounds of torque. The drain plug for the oil pan requires 33 foot-pounds of torque to prevent leaking. The oil jet bolts to the block with 12 foot-pounds of torque. The 6 mm bolts on the oil pump require 8 foot-pounds and the 8 mm bolts require 17 foot-pounds of torque to join with the block. The starter-to-transaxle bolts require 33 foot-pounds of torque.
