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.

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.

Thanks for the info

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:
