December 22, 200816 yr comment_269436 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...

December 22, 200816 yr comment_269437 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.

December 23, 200816 yr comment_269497 Would the 1000 miles adjustment apply also to a rebuild engine? Link to comment https://www.classiczcars.com/forums/topic/30301-valve-adjustment/#findComment-269497 Share on other sites More sharing options...
December 23, 200816 yr comment_269498 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.
