During engine assembly, an incorrect exhaust rocker
arm shaft may have been installed. The incorrect shaft
does not allow proper lubrication to the camshaft
journals, which results in excessive heat buildup. In
some cases, the camshaft holder bolts loosen, allowing
the rocker arm shaft to move and causing a clicking or
a tapping noise.

Twenty-four (24) customer owned 2008 Civic Si’s may have the wrong exhaust rocker arm shaft installed in the cylinder head and need to be repaired. Six (6) additional vehicles have already been repaired.

CORRECTIVE ACTION
Replace the cylinder head assembly.
NOTE: The loss of lubrication is only in the camshaft
and rocker arm area. There is no need to replace the
short block assembly.

 

Dang thats pretty intense, had not heard of this yet.

 

Am I correct in assuming that only the 2008 si is affected?

hooray for having a 07, I guess.

pretty much every Honda 4cyl engine [and every smaller 4 cyl regardless of manufacturer] I have ever heard has a slight tick to it.
