When, exactly, does it "burn up"? I remember your past threads. Does it get hot when you connect the battery, or when you turn the key on, or when you turn the key to Start, or when the engine is running? I would narrow it down to one of those four, it will tell you a lot.

Isn't that what the condenser (capacitor) in the distributor is for? The ballast is to keep the coil from burning up. It's the thermomechanical version of "current-limiting" ignition modules. Kettering.

This Beverly Hills car actually looks kind of interesting. Beat up, but hard to tell how bad. https://www.beverlyhillscarclub.com/1971-datsun-240z-c-13399.htm

I think is where BaT RNM's end up. https://www.hemmings.com/classifieds/cars-for-sale/datsun

This was on BaT a short while ago. Made it to $27,250. Looks like the reserve was $45,000. Red... The Hemmings article uses the BaT verbiage as the seller's description. I wonder if BaT allows that. Seems like free work. It's not fantastic but still has that tone to it. https://www.hemmings.com/stories/2022/01/14/after-some-minor-updates-and-refurbishing-this-1971-datsun-240z-is-primed-for-long-countryside-jaunts https://bringatrailer.com/listing/1971-datsun-240z-201/

I've had a brand new slave cylinder leak. Sometimes you'll find machining grit inside if you take them apart, even brand new. Quality control on aftermarket parts is just poor. Take it back and see if you can exchange for a different brand, then take it apart at home and clean it up inside before installing. I think that EuroDat has seen similar if you want to search for past posts about it. @EuroDat

I'm saying just buy a complete used R200 with 3.9 gears. Typically found in the 1980 -1983 280ZX 5 speed cars. They're out there. You could probably buy a complete junked 280ZX for less than the cost of new gears if you find them. Actually, I doubt that you'll be able to find gears for sale. A used R200 is probably your only option.

It would be easier and more effective probably to just buy a 3.9 R200 with good gears. I don't think I have ever seen anyone talk about worn gears on their R200. But here are the part numbers if you want to try to track new gears down. http://www.carpartsmanual.com/datsun/Z-1969-1978/power-train/differential-gear/r200/13

280Z https://bringatrailer.com/listing/1975-datsun-280z-34/

Too bad the 280Z's don't generate the same excitement. Seems like the 240Z's are becoming collector things, like Pokemon cards. The value is in the scarcity. The value could disappear overnight once a new thing comes along. No offense intended, just a thought. https://cardcollector.co.uk/collecting-pokemon-cards/

I'm not trying to cause trouble. Just talking about an interesting car. Your build thread is too long to search through to find the explanation. It really stands out in the pictures.

This is for AC hoses? Looks like a great job on the car. Good luck.

Isn't it really a resto mod? Resto perfecto maybe. Parts have been replaced with better parts, but they are not original, therefore not resto. Just pretending I'm a car show judge. Anybody know what this thing is...

Looks like the silver foil from the top of a gallon jug of oil. ? If it is a bearing failing you will hear it eventually. Measuring cylinder pressures, examining cam lobes, checking timing chain wear...those are the typical things you'd do to determine engine wear. 136,000 miles is not a huge number for these engines.

What engine? How many miles? What do you know about it? Can you post a picture of the copper flakes? Might just be from the washer on the drain plug.

Is this yours Cliff/site @siteunseen ? I see orange. Condolences if it is. It's been Californicated. https://bringatrailer.com/listing/1971-datsun-240z-210/ "This 1971 Datsun 240Z was acquired by the seller four years ago while in Alabama, and was subsequently repainted in metallic green."

Might this be part of it? Sorry.... https://www.theguardian.com/sport/2022/jan/11/georgia-alabama-national-championship-game

All of the 5 speeds through 1983 are called FS5W71B. The label doesn't tell everything about what's inside.

You can buy this length in coated professionally prefitted tube at your local auto parts store. Run a piece of string or wire over the orginal to get the length. Bend the new one to match the shape. I might have mentioned this already.

Your antifreeze should contain corrosion-inhibiting chemicals. The block itself will rust if you don't use proper antifreeze, it's cast iron.

You might be thinking of stamped steel versus cast iron. I've never seen an aluminum impeller. Compare the AISIN and Airtex pictures to the others. I think that most people like the cast impellers. They were hard to find for a few years but it looks like they're back. https://www.rockauto.com/en/catalog/nissan,1978,280z,2.8l+l6,1209260,cooling+system,water+pump,2208

Can you describe the material and the process used to make it? It looks interesting. I made a time stamp of the video that shows the broken bearing holder. for the impatient people. Good luck, think about doing the 280Z distributors. They have the same problem. Even the points distributors. 240Z repro parts might be a good market.

Definitely some odd stuff to think about.

Seems obvious that it got crunched in the front, just by the pictures. The seller is not the owner, it's a sales shop. The guy has to know but he can claim he does not. His "techs" did the work, not him. Plausible deniability. It got to $20,550 but RNM. Does Nissan paint do this, even on a 71? The roof should look the same. It's been crunched and repaired.
