78 280z very loud screeching at idle
When you open the throttle intake manifold vacuum drops. Less air would get pulled in through the hole, if it is a gap or hole, due to lower vacuum. The BCDD is a good place to look. It's under the throttle body. The crankcase is under vacuum also, from the PCV system. So any hoses that are involved with the PV could be leaking. Really, any hose on the engine, that's not a water hose is a vacuum hose. Get a spray bottle with water in it and spray hoses while it's squeaking. Should change pitch if it sucks in some water. Won't hurt the engine.

Has the engine had any work done on it? Always good to know the history of a car/engine. Your video was with the belt on. Should have done one without it, it will be fine for a minute or two. I'd guess something in the damper pulley area.

Something horrible just happened - an ad autoplayed "music" on the CZCC site
Actually it looks like the ad that autoplays is a video ad, but it's one of those that plants itself in the middle of a person's post. This one just played an ad for The Voice. @Mike Only posting because you said that autoplay is not allowed. If things have changed I'll stop compalining.

I managed to get a picture of the offending audio ad. It was for King 5 News. Here's the picture. It seems to be audio only. There ain't no ad where an ad usually sits.

Odd power loss on occasion........
Sounds a lot like loose crud clogging the inlet line screen in the fuel tank. The crud gets sucked on to the screen and clogs it then floats free when the engine dies. You might drain the tank and see what you find.

280Z Barn Find
Good luck and be careful with it. Read the recent thread about the 31K 240Z, that's what my joke about value was about. If you want top dollar, you have to do what the collectors want, not what you think they should want. They're a finicky bunch. Everything that you do to it becomes part of its provenance. Keep every scrap of paper that came with the car, even the brown wrapping paper. Every part imprint on a piece of paper is like the Shroud of Turin.

280Z Barn Find
Oops. Just kidding... I really don't know if being part of an AMMO cleaning products video is good for the resale. The high end collectors want a nice story behind the car. Don't know much about AMMO. Maybe they're the stuff. Good luck to him. https://www.ammonyc.com/

280Z Barn Find
That's a $400,000 car. I watched the video up to the first ad. Too bad it got the undercoating treatment. Edit - wait, I just watched more video. They used the car as an advertisement for cleaning products. It's a $5,000 car now. Shame. Seriously, I bet they knocked $30,000 off of that car's potential price, if the goal was to sell it.

Spindle Pin (rant)
I found that spinning the pin in the bore loosened things up quite a bit. I used a lug nut on the end of the pin and squirted lube in the lock pin hole and the the ends, then just spun it for a while. If I was doing another I'd probably rig something up to spin and pull at the same time. Moving the spindle pin back and forth in the bore also helps, probably distributes the rust away from the pinch points. I also got caught by the pin being rusted in to the sleeve inside the rubber bushing. I found the the rubber would pull the pin back after I pounded it in. It was confusing for a while. "I know I saw it move but there it is where it started" WTF!".

Random Misfire while cruising

Oh Canada. Did you put some desiccant in there with it? And mousetraps? Don't want to find fungi-covered mice when you unpack it in ten months.- Distributor Springs. You’d think this was easy...
Adding to zKars just-now post - That makes sense jonbill. But still doesn't really tell if there should be one or two for a specific distributor. Looks like one has a steeper advance rate than the other. 7 degrees in 500 RPM versus 5. Distributor degrees, 14 versus 10 in crankshaft. Maybe that's one spring versus two.- Distributor Springs. You’d think this was easy...
The picture shows an A and a B spring though. Always somethin'. The test would be how much unhindered rotation of the shaft is there with just one spring. The springs are there to balance the shaft rotation due to the weights moving. No spring should mean that one weight is just flopping around. Maybe the short slot weight doesn't move at all. The words imply that it doesn't move, maybe, "it does not leave clearance either at start or end"., but then why they do they show a spring? Confusing.- Distributor Springs. You’d think this was easy...
I don't know what all this means but... One says spring, one says set. And the 72 FSM shows the unbalanced slots. I alternated pictures and links, hope it makes it through. http://www.carpartsmanual.com/datsun/Z-1969-1978/electrical/distributor/240z/for-manual/to-aug-71/6 http://www.carpartsmanual.com/datsun/Z-1969-1978/electrical/distributor/240z/for-manual/from-sep-71/5- 31K Miles Series I 240Z Up for Auction on BaT - Over $100k on First Day!
If I ever find a 240Z in a barn I'm going to just have the dirt it's sitting on carved out and placed on a trailer with the car on top and whatever happens to be on the car itself. Cleanup will be whatever hay/dust/dirt/droppings are blown off on the way to its new home prior to taking 300 pictures and posting on BAT.- 31K Miles Series I 240Z Up for Auction on BaT - Over $100k on First Day!
I noticed that too. Here's the Green Monster, 21,000 miles. You can see the blue paint that Blue246 was talking about also. Dogpile!!- Something horrible just happened - an ad autoplayed "music" on the CZCC site
Just had another horrible noise episode, definitely from this site. I saw AK260"s comment and went to the beginning of the 31K Z thread and started re-reading. I clicked open Page 2 and about ten seconds later "too important to miss, tonight at 6..." blasted through the speakers. I should have muted and tried to figure out which ad was causing it, the little one that sits on top of everything at the bottom of the page so you can't read the words below, or the big one at the top of the page. Instead I just closed the tab and the noise stopped. So @Mike you said that you would never have autoplay ads on the site but somehow they have slipped through. Those marketing guys are persistent and clever. Probably better at internet stuff than the Russians. I'll try to figure out which visuals match the words if/when it happens again. I wonder if it's possible to have autoplay audio with no visual associated.- 31K Miles Series I 240Z Up for Auction on BaT - Over $100k on First Day!
I think I found the key to verifying low miles. "Original cosmoline". 7:00. It actually is pretty impressive that they found some. I tried to work at a place that details cars when they came off the ships, before they go to the dealerships, and that stuff is everywhere. I didn't last, you have to be a human squirrel to do high speed car detailing.- 31K Miles Series I 240Z Up for Auction on BaT - Over $100k on First Day!
Different colors probably go on at different thicknesses due to their ability to cover. The Green Monster video was pretty good but that guy kind of just walked around and took a bunch of measurements but didn't say much about why some cars had different thicknesses, besides assuming that a repaint would be thicker than original paint. He assumes that a second paint job is always thicker, like a painter doesn't strip and sand areas to make them smooth, before painting. It would be better to have 20 or so specific locations to measure at, and measurements at those points from a whole set of cars, as a database. The old beat-up $5000 Z's probably have plenty of untouched paint to measure. That would mean more, I think, than these random measurements. Good idea, questionable execution.- 31K Miles Series I 240Z Up for Auction on BaT - Over $100k on First Day!
Quality and/or calibration? Method? Training? https://www.measurementshop.co.uk/blog/guides/all-you-need-to-know-about-thickness-gauges Or the red car has a second coat of paint? We need microscopy on a paint chip cross section.- 31K Miles Series I 240Z Up for Auction on BaT - Over $100k on First Day!
What's funny is that in the 70's I think that they still had a guy with a spray gun painting parts as they came down the assembly line. I think they even masked off and repainted parts if there was a ding from a clumsy assembler. Probably tons of variation in these old cars. Today it's all robotics and dip tanks. Paint thickness readings seem like a strange new criterion for originality. What if they measure a rust spot before it bubbles?- New to the ZXcrew!
Use a meter and measure voltage at the battery terminals while it's running. The dying could be a separate problem. - I shrink wrapped the Z today
