Check the block breather to pcv hose. They go soft and gummy.

Your z has the improved AAR hose routing so that is good too.

This will get you into trouble:

Looks like you have a little coolant seepage at the thermostat housing. Could be a loose bolt, maybe. Or just a plain ol' dried up gasket.

Thanks guys, great info. @240260280 Philip, are you still selling those fuse blocks to replace the fusible links? Me want.

The fantastic 77 color wiring diagram was created by Wayne @wal280z.

Here's the latest. It's Revision "M". It includes the two changes mentioned above (voltage regulator and illumination light in the Temp/Oil gauge):

And if you want to see any of the history of changes, here's a thread with some details:

That is a beautiful diagram, I'm going to put that on a stick and take it to a print shop to see if they can make me a full size copy.

Thanks again.

I may have a few kicking around.

Yeah, I can't imagine what stage of electrical disrepair I would be at currently if it weren't for Wayne's wiring diagram. There are honestly projects that I would have simply not tackled if I had to spend that same time tracing the wires on the stock multiple page monochrome diagram.

OK guys how the heck do you get this panel out without breaking it, how did they get it in? 

Starting in 74 Nissan stopped offering White as an interior colour and switched to Off White, I have also seen this colour called Beige and Ivory. My question is has anyone bought these seat covers from MSA and what do they really look like? Is there anywhere else that makes a stock looking Off White with the fabric in the middle?  http://www.thezstore.com/page/TZS/PROD/40-2651

Ahhhh, now I see, I thought that the whole flange was welded on.

So this spare tire is pretty much dedicated to have a can of compressed gas to fill it up, what is everybody using? The original can has something sloshing around inside but I sure wouldn't want to depend on it.
