Captain Obvious

I think that is OSHA required safety gear while you are in the Orgasmatron:

If connected and working properly, the system is supposed to store the vapors in the can with the engine off, and then pull them out of the can and burn them when the engine is running. In theory, the carbon canister is supposed to be a temporary holding vessel and you are supposed to empty it ("purge") when you run the engine. However, I wouldn't be surprised to learn that the emptying process is never 100% complete and it could eventually saturate over the years. I haven't looked into it, but that wouldn't surprise me. Is that what happens?

@Patcon Over in this completely unrelated thread: https://www.classiczcars.com/forums/topic/60181-cleaning-the-filter-on-the-carbon-canister/ The subject of activated carbon came up, and as a result, I found this on Wikipedia: "Industrial application: One major industrial application involves use of activated carbon in metal finishing for purification of electroplating solutions. For example, it is a main purification technique for removing organic impurities from bright nickel plating solutions. A variety of organic chemicals are added to plating solutions for improving their deposit qualities and for enhancing properties like brightness, smoothness, ductility, etc. Due to passage of direct current and electrolytic reactions of anodic oxidation and cathodic reduction, organic additives generate unwanted breakdown products in solution. Their excessive build up can adversely affect plating quality and physical properties of deposited metal. Activated carbon treatment removes such impurities and restores plating performance to the desired level." Here's the URL for the page: https://en.wikipedia.org/wiki/Activated_carbon I never knew any of that, and filtering used solution through activated charcoal filter might help with what you're doing?

The turn signals say 240, but those are clearly 280 bumpers!!

Oh yeah... And the serious part. Activated charcoal is funky stuff and I'm not sure how it would take to being completely doused with water. What makes it so cool is the amazingly gigantic amount of surface area it has for it's size, and I'm not sure how well it would dry out. I would shop-vac as much of the crud as you can off the bottom, put a new filter on it, and use it.

Nailed it. "Told my girl I have to forget her Rather buy me a new carburettor."

Queen wrote a song about this.

And forgot... I think dripping ABS solvent down into that crevice is a really risky move. I think that if it wasn't securely glued before you do that, it most certainly will be afterwards!

Mice used your old filter to build a nest a very long time ago. AC Delco claims to have a replacement available on Rockauto for $1.48. Look for ACDELCO part number A478C. I've heard that Rockauto is no fun in Canada though. Shipping costs are high?

"I know, right?" For something so seemingly simple and stupid, it's really a PITA. I did mine while in the car but while the dash was out. And while it isn't as bad as on your back upside down head under the dash, it was no picnic either! You CAN take just the individual contacts out of the connector shells and leave the shells clipped into the white plastic support bracket. What (in the grand scheme of things) is it that you are trying to do?

Cool. Here's to hoping the few threads you caught are enough and you don't have to put more work into it. And not that it really matters at this point, but... I don't know if all the clutches work this easy, but I've found that simple gravity bleeding works fine. Maybe one or two pumps at the very end just to make sure all the air is gone, but I've had good success with just letting Sir Isaac Newton do most of the work.

Yeah, that was over in this thread: https://www.classiczcars.com/forums/topic/60007-78-280-re-assembly/?tab=comments#comment-549457 If you have easy access to both front and rear, it should be a lot easier than trying to do it inside the car.

Thanks Leon. A plastic zip tie is a much better idea than using a marker. I might even be able to get that around the shaft even with the bellows installed. Might be impossible to see it once it gets pushed up though. Maybe I'll give it a try and see what happens. Thanks for the great idea regardless.

I did not know that... So they ditched the ballast for the 78 and changed the ignition module? I mean, I know the module was different as the connector design is completely different, but I was not aware that there was any functional difference. I thought it was just cheaper for them to plug in one connector than make the six or so connections on the prior versions. Has anyone heard any "the 78's burn better" claims or rumors because of it?

Oh, and I used VW connectors on my injectors as well, but I used a different version with end release clips instead of the one single side release. I found I liked them much better for the injectors, but I liked the side release in the other locations better. I used to have a pic posted, but photobucket extorted it out of existence. I'll get a new pic loaded up when I get a chance.

As an aside, remind me sometime to tell you a story about the fusible links and why they are a ticking time bomb. Post up all my measurements and investigation and stuff. But in the meantime, back on topic... I found the cheapest place to get all the links at the same time was off ebay. The ones I bought were purported to be genuine Nissan, and did all four links. You need the 77-78 version, and it should have three red (which are actually brown), and one larger black one. I did a quick look on ebay, and it seems they are still plentiful. A couple item numbers that seem to be the correct set: 323288133774 312138092640 223006930529 Or search for "Datsun Fusible".

I'm not so sure it's an aftermarket recovering. The 77 seats all had that sort of "woven textured" vinyl inset on them, but I think it's just an embossed pattern in a solid piece of vinyl. In other words... It mimics a weave, but I do not believe it is actually woven. I don't think there are any holes in it. I think it's just a pattern on the surface. Now as for the different colors... I consider it completely conceivable that the embossed vinyl and the smoother (leather grained embossed) vinyl came from different vendors or at least could have different compositions, and hence, have weathered differently over the years. So all of this is academic if you're just going to swap over to a black interior, but thought I would mention it.

Excellent. Thanks for the pics showing that mark. I've never seen that before. So, especially with that confirmation of the mark on the hub, I'm pretty confident that things are going to be OK. Wiggle the calipers around with very light pressure until you can achieve the absolute lowest reading you can get. Get the two jaws perfectly opposite each other to avoid the hypotenuse measurement. And check those shiny spots under magnification. In fact, I would use magnification on both sides of the hubs. Just to look for any anomalies or surprises. That's how I found the upset material on Matthews from the previous attempts to force the bearing in while misaligned. It was all nice and shiny looking to the naked eye, but I felt something funny with my finger. It wasn't until I looked with magnification that I was able to identify exactly what was going on in there. I suspect yours are just dents inward from the pressure (which is fine), but it's worth the thirty seconds to double check.

I was just kidding about the errors on the Rev M. I think I turned up something minor recently, but it was so inconsequential that I don't even remember what it was. I have no significant issues currently. Only thing I would warn you about is the position of the fusible links. What is shown on the diagram is NOT the correct physical location of the links under the hood. This is the correct positioning: And for the fuse values, here's a couple pics. This is the 77 cover (which BTW is a little different than 76): And here's a snipped from the FSM showing the artist's rendering. The fuse values are the same, but the printing is a little different:

Leon, Thanks for the input and I understand about the loss of travel and the increased risk of bottoming-out. I'm running KYB inserts, with stock springs and rubber bushings. In other words, pretty much stock 280Z with KYB's. I've been driving with this setup for a number of years now and I don't believe I have ever bottomed out the stock suspension. Ever. So how close to the limit do you think I am now with the stock set-up? Any guesses? If it weren't for the rubber bellows being in the way, I could put a marker line on the strut shaft and go for a spirited drive and see how much of it was worn off. And Chas, Yes, you're absolutely right. One inch drop on the rears is easy. The idea was just for the front.

Whoa. I got a serious case of diagram envy. That thing is beautiful! I guess now is not the time I should bring up all the mistakes I found recently, huh?

Well I put a whole bunch of my thoughts in your Lily thread: https://www.classiczcars.com/forums/topic/55369-1971-hls30-14938-lily-build/?page=8&tab=comments#comment-550587 Haha! Am I missing the joke here or something?

I'm not a suspension guy, and I got a stupid question... What would happen if I were to remove the lower spring perches from the strut tubes and reattach them an inch lower than they were originally? Make that change and nothing else... Put it back together with everything else the same as when it came apart. No adjustable threaded collars. Stock springs with a lowered bottom perch. The whole sprung weight of the car sits in equilibrium on the springs, so with a lower perch, the same weight should compress the same springs to the same length and that would lower the car by an inch, right? And the only down side would be that I would be at greater risk of bottoming out the strut on compression, right?

Accident on the way to the emergency room. It's like ten thousand spoons when all you need is a knife. So what dimensions are you talking about? Last I saw, you were messing with the calipers I sent and you were still measuring a couple thousandths larger than expected. Did one of us miss a post somewhere?

All that means is that it'll come back again some time in the future.
