1997 HONDA CIVIC bolt sequence

11. When installing the cylinder head cover, hold the
head cover gasket in the groove by placing your fin-
gers on the camshaft holder contacting surfaces
(top of the semicircles)
Set the spark plug seal on the spark plug tube.
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
NOTE:
. Before installing the cylinder head cover, clean
the cylinder head contacting surfaces with a
shop towel.
. Do not touch the parts where liquid gasket was
aDolied.
. Take care not to damage the spark plug seals
when installing the cylinder head cover,
. Visually check the spark plug seals for damage.
. Replace any washer that is damaged or deterio-
rated.

NOTE: Make sure the timing belt drive pulley andcamshaft pullevs are at TDC,
Loosen and retighten the adjusting bolt to tensionthe timing belt.
Install the lower cover and middle cover.
NOTE: Clean the middle and lower covers beforeinstalling.
Install the crankshaft pulley, then tighten the pulleybolt (see page 459).
Rotate the crankshaft pulley about five or six turnscounterclockwise so that the timing belt positions onthe pulleys.
Adjust the timing belt tension (see page A611.

lf the camshaft and crankshaft pulleys are not posi-tioned at TDC, remove the timing belt, adjust theposition following the procedure on page &63, thenreinstall the timing belt.
After installation, adjust the tension of each belt.

Installation
lnstall the cylinder head in the reverse order of removal:
NOTE:
. Always use a new head and manifold gasket.. The cylinder head gasket is a metal gasket, Take carenot to bend it.
. Rotate the crankshaft, set the No. 1 piston at TDC (seepage 6-63).
. Do not use the middle cover and lower cover forstorang removed items.. Clean the middle cover and lower cover before instal_lation.
o Replace any washers that are damaged or deteriorated.
1. Install the cylinder head gasket, dowel pins and thehead oil control orifice on the cylinder head.
NOTE: Clean the oil control orifice when installing.

2, Tighten the cylinder head bolts in two steps. In thefirst step, tighten all bolts in sequence to about 29N.m (3.0 kgf.m, 22 tbf.ftl. ln the final step, tighten inthe same sequence to 83 N.m (8.S kgf.m,6t lbf.ft).
NOTE:
. Apply clean engine oil to the bolt threads andunder the bolt head.. We recommend using a beam-type torquewrench. When using a preset-type torque wrench,be sure to tighten slowly and not to overtighten.. lf a bolt makes any noise while you are torquing it,loosen the bolt, and retighten it from the 1st step.
