king bee66 Posted August 16, 2011 Report Share Posted August 16, 2011 on an a14 its .0098 in / .25 mm Quote Link to comment
ggzilla Posted August 18, 2011 Report Share Posted August 18, 2011 No no no. I'm looking at the 1981 Datsun 210 Factory Service Manual in front of me, and it says this: Valve Clearance(Hot) mm (inch) Intake: 0.35 (0.014) Exhaust: 0.35 (0.014) Nissan recommeneded 0.35 from 1971. In early 1971 they listed 0.25 but there was a Technical Service bulletin that said stop using 0.25. That's for a stock cam. If you have an aftermarket cam, it can specify even more clearance or sometimes less. Use the recommendation of your cam vendor. Quote Link to comment
king bee66 Posted August 18, 2011 Report Share Posted August 18, 2011 my bad, .25 is the cold clearance Quote Link to comment
ggzilla Posted August 18, 2011 Report Share Posted August 18, 2011 0.25 is a little tight for the cold clearance. Nissan only recommends adjusting it Hot, but if you do it cold, use 0.33 mm (0.013 inch) @ 65 degrees. The Cold clearance needs to be tighter than Hot clearance because the aluminum head and the steel valvetrain expand at different rates. With the A-series engine, the difference difference between Cold (65 degrees) and Hot (180 degrees) is only 0.03 mm or 1-thousands inch. Quote Link to comment
