Here is the torque for the head and sequence for the A-12 engine, let me know if you have more questions, Thanks ROY!
I knew you would ask that ,they do not list it I think it is around 8 to 10 ft.lbs no tighter , do it slow, so you do not bind the shaft or the rockers this can snap the rocker shaft if not careful, Thanks ROY!
Let me know if you need more help , Thanks ROY!
NEED PROCEDURE TO ADJUST ROCKER ARM ASSY ON A-12 NISSAN 4CYL 1998-2000 ENGINE ??
The A-12 engine the rockers have a screw down the middle with a lock nut 12mm, the easy way to do this is put the engine on TDC remove the distributor cap and look at the rotor on number 1 cylinder, both intake and exhaust valves will be on the highest point , then adjust the clearance with a feeler gage, the clearance should be (.010" )intake and exhaust rockers, if the engine is warm the clearance is (.010") intake and (.012") exhaust. then rotate to the next cylinder number 3 and do the same adjustment until all are set. if still noisy do the warm adjustment , Thanks let me know if you have more questions, ROY!
