1973 Datsun 240z S30 Manual Comparison Trouble

Yes, the valve clearance is measured between the cam and rocker.

The number one cylinder is at the front of the car. The rest are in order going toward the back.

I prefer to measure the valve clearance one cylinder at a time following the firing order (153624).

Set the base timing to the '73 setting with the vacuum hose disconnected and plugged, and the idle at the specified RPM.

The air galley, the metal tube running horizontally near the top of the photo, looks rusted out. If it's not leaking exhaust fumes yet, it probably will soon unless it's not as bad as it looks. A new one may be available if you want to keep it stock. Many have removed them and welded or plugged the holes in the exhaust manifold.
