Garagegoon Posted May 16, 2008 Share #1 Posted May 16, 2008 Ok... Trying to hit two topics on one post. Is there a diffirence between the harmonic balancer on an AC equiped car versus a non AC car. And... I have a little valve tap goin on when the car warms up.... Is that normal. I have heard others with the same noise. I come from the world of american made iron and am not used to the Z cars yet. Just learning the ins and outs. Link to comment Share on other sites More sharing options...
d240zx2 Posted May 17, 2008 Share #2 Posted May 17, 2008 There is a difference in the harmonic balancer on early Z cars. Not sure about post-73 years.No, valve clatter is not normal. You need to check/adjust valve lash per the FSM. Having said that, you CAN hear some light valve train noise, but mine sounds the same cold or hot.Frank Link to comment Share on other sites More sharing options...

Nissanman Posted May 17, 2008 Share #4 Posted May 17, 2008 Apart from having an extra pulley on the crank damper, the ignition timing marks are located in a different place. Take this into account if you are mix and matching:ermm: Link to comment Share on other sites More sharing options...
