Mike B Posted December 22, 2008 Share #3 Posted December 22, 2008 The service manual for a 240Z says to check and adjust them as needed every 6,000 miles.-Mike Link to comment https://www.classiczcars.com/topic/30301-valve-adjustment/#findComment-269434 Share on other sites More sharing options...
scotts pearl Posted December 22, 2008 Author Share #4 Posted December 22, 2008 Thanks alot,,, does anyone know the clearance specs for a 78 280 Link to comment https://www.classiczcars.com/topic/30301-valve-adjustment/#findComment-269435 Share on other sites More sharing options...
DeesZ Posted December 22, 2008 Share #5 Posted December 22, 2008 (edited) If I recall correctly, the interval on my '71 & '72 called for adjustment of clearance every 6,000 miles. (I do it every spring just to keep in touch with the girl.)(edit) Ooops... Mike B beat me to it...

sblake01 Posted December 22, 2008 Share #6 Posted December 22, 2008 (edited) The 280Z owners manual says to do the first adjustment at 1000 miles and every 12 months or 15000 miles thereafter. Keep in mind that this is for a new car so you can disreagard the first adjustment. Intake-.25mm(.0010") Exhaust .30mm(.0012")-Hot.

Walter Moore Posted December 23, 2008 Share #7 Posted December 23, 2008 Would the 1000 miles adjustment apply also to a rebuild engine? Link to comment https://www.classiczcars.com/topic/30301-valve-adjustment/#findComment-269497 Share on other sites More sharing options...
Arne Posted December 23, 2008 Share #8 Posted December 23, 2008 Would the 1000 miles adjustment apply also to a rebuild engine?IMO, yes. Assuming it was a true rebuild with a valve job. In fact, on a rebuild I might do my first check at 500 miles, and then again at 1000.
