Best present ever! My neighbors, young money makers with 2 young babies that i took under my wing, helping in their yard and feeding their animals just dropped of my present. I'm speechless... There really are Christmas miracles.

RACEWR X, I really dont know.....they are pretty small. I went in heavy and soaked it down with brake parts cleaner. Blew it dry , put a tiny drop of very light oil on each staff bearing. iIt seems to be running well. I let it run all day, and it kept good time. Put it all back together. I got my dash back from just dashes. Pretty pleased with the job they did. I put it all together today. I replaced all the lights with LED's. Only three of the original bulbs were working. Cant say enough about the importance of taking a ton of pictures during disassembly. That really helps.

They watch me struggle to crank my old br600, 2009 model. It won't hold fuel so pull pull pull but when it starts it does fine. It needs a $65 carb and when I put that on I'm putting this new one on my mantle!

I have some 2 part jb weld epoxy that is very clear when cured. It will probably be my product to try. I may give it a shot tomorrow while cooking a brisket .

28d F Sitting In an elevated tree stand in 10 mph winds. Pretty cool for a southern boy!

Somebody posted this stuff a day or so ago. It's close to what my dentist uses on my teeth. Amazing how it works at the dentist and now that I can jb weld my teeth myself no more white coat anxiety and a lot less money.

I'd break it off and super glue it.

Or I could repair these and drop them in and buy newer ones later if it bothers me. But I could drive the car sooner using these...

I can't find @240260280 photo of all his cars covered in his driveway, Nova Scotia I think. Did find ol' Blue pretty deep.

We 've got the same feeling here. 20 f this morning and tonight along with freezing rain that is predicted to end up 1/4"-1/2" thick. That means trees and power lines down around here. Thank God for our wood stove. I keep thinking about our Canadian neighbors and even stop whining about the cold when I remember them.

I'm somewhat anxious about this drop in temp. Haven't had the problem since 1989, now it's back. Hopefully there will be no damage if I just stay home. No early morning drives for me. Stay safe friends and have merry Christmas.

I've never heard of a differential cooled with fuel. I doubt I would have even considered it as an option.

Not willing to re plant the seeds of rust on the Z, So I dug out the Honda Trail.

Interesting - I would love to know exactly what diff coolers they were prepared to install for customers, and where they would put it. This is the point where we as enthusiasts wish the designers would be able to to start quoting part numbers, haha! For others who are following this thread: anecdotally (and I don't have the exact figures in front of me ), differentials seemed to play a significant role in rally retirements during the early years. As a solution, the "Fuel-as-diff-coolant" strategy does appear a bit outlandish to me on its surface, and it's effectiveness is clearly very dependent on the amount of fuel left in the tank, among other things. I can't really speak to whether it actually provided a noticeable reliability improvement versus not having it at all. But it is certainly a creative, compact solution!

Yeah it's nice to live where you do you rascal. Merry Christmas Dennis.

This time of year it's good to live in the desert. It will be 81º here on Christmas Day. Stay warm!

From Mr. Uemura’s Story: DEVELOPMENT PROCESS - - Vehicle Durability Tests - - - Heat Resistance and Cold Resistance Tests The heat resistant performance was evaluated at an external temperature of 95ºF (35°C) for the domestic models, and at 104ºF (40°C) for the North American models. The tests were mainly conducted on the heat-resistant chassis dynamometer. However, because the wind flow can be different from the vehicle tests, performance was also evaluated on the test course. Eventually, field tests for this model were done in the United States and Canada. The heat resistance test done on the chassis dynamometer includes many items, such as whether the temperature of the water or oil is normal during high speed operation, whether the engine speed becomes unstable while the engine is idling after high speed operation, and whether the engine can be restarted after the ignition is turned off. If it fails any of these items, heat resistance performance is considered insufficient. We aimed at keeping the engine oil temperature within a specified range even if the car ran continuously for 118 miles (190 km) without an oil cooler. In fact, we had no problems with the engine oil temperature. The differential was also designed to keep the oil temperature in a specified range even after 118 miles (190 km) of continuous driving. However, because it was at the far rear of the floor, the differential did not get sufficient wind even if a baffle plate was used. In the end, it was not able to clear the 118 miles (190 km) continuous driving at a 104ºF (40°C) external temperature. If consumers complained, we were prepared to offer an optional oil cooler for the differential oil, but this problem did not arise. Probably as no one drives a car continuously at such high speeds in the United States, and because temperatures do not go up that high in Europe.

Correct- it is a heat exchanger, which cools the differential fluid with gas. I've yet to get it working, so I can't speak to how well it works, unfortunately. Worth noting, this diff cooler is not a new "discovery" by me, as it's been previously well documented many years ago, via a 1992 article in Race & Rally, which told the story of the early days of the 240Z Works rally program through the lens of the mechanics at Old Woking Station.

For your resto? i would sell some spare parts and buy some new (copy's) of the rear lights. They are a bit lighter i think then the new originals but a very nice solution.. you can always restore the old ones and sell 'm sheap.. (with some polyester.)

I assume they are using the fuel to cool the diff. Liquid to liquid intercooler. Seems an interesting choice but I'm sure some engineer worked it out

Thanks for all the replies. I guess I am still old school and would prefer working the old tank but there is a point when the old has to go and a new piece must be used. I will do some more research as time permits on these options. Several years ago I sent the tank from our 69 Datsun 2000 to be renewed. If memory serves me correctly it was $50-$60 to ship it out and later got a call that it could not be done due to the internal baffles and rust condition. I passed on spending another $50-$60 to have it returned and put that money towards a small plastic tank from Summit Racing. There is quite a bit more involved with the 280Z tank as far as plumbing and mounting is concerned. Thanks again and Merry CHRISTmas-John-Lugoff SC.

Seeing the added mileage is great to see.

Yes, the KF panel is only an inner rocker reinforcement panel. The item number 1 in the parts manual dot com page is a full panel, from the plenum down to the pinch weld where the inner and outer rocker panels, and the reinforcement panel come together. Somewhere the outer edge of the floor pan ties in there too.

Very nice!

Raw gas smell or burnt exhaust would be a good tell.

From the Remembering the Original Road Atlanta group on Facebook: The picture below is from Oct 1980 According to the comments, it's Jeff Curlee in the 280Z in front. The 240Z was driven by the late John Williams. That 240Z is still owned by someone I know, and he tracked the car at the Mitty a few years ago.

This looks like it might have been taken in the 1980’s at Road Atlanta? 9 o’clock, yellow Z. Nicely presented…

I would suggest you use glazier's mastic 'rope' as the sealant between the tail light lens and housing. It'll provide all the seal that you need and it's not so sticky as to make future disassembly a problem. The alternative is liquid window caulking. There is a 'strippable' version (clear) that would probably be a better bet than the more permanent types. Don't overlook the little drain holes at the bottom of each lens. Each drain hole should be fitted with a small rectangle of felt (cut to shape from a sheet of 1/8" thickness, purchasable from a crafts store like Michael's). The purpose of the felt is to keep small, uninvited visitors (spiders, etc.) from setting up house inside your tail light assembly. The lenses will come up nicely with buffing. Try not to buff away the raised manufacturer's info. You'll need to leave that area as-is.

piano wire installed. Works like a charm!!!

Might be a flip or somebody just got tired of it. Purchased on BAT 3/7/2019. Now it's back. (p.s. it has 10,000 miles added since the first sale). https://bringatrailer.com/listing/1973-datsun-240z-224/ Previous - https://bringatrailer.com/listing/1973-datsun-240z-85/ Sold for $38,250

Brake parts cleaner 😁

You know you have a real mental disorder when you decide to take the time to tear into the 240 clock to try and get it running. What an intricate mechanism. I got it running. For how long, who knows. I will check it in the morning. Merry Christmas! Video evidence: 20221220_195857.mp4

This is what came to my mind also. Plug #4? It's a single cylinder problem. Changing things to fix one cylinder will affect the other cylinders. Also remember it has a performance cam. And it's a CA Datsun engine. If it was mine, I'd find a used stock unmolested engine and swap it in.

As lots of americans don't realise, the 260z was made till 1979 when the 280zx came out.. so there are a lot more 260z and 260z 2+2's ... In america there was the 280z and the rest of the world got the 260z's.. I don't know for the rest of the world but we overhere in the Netherlands could not GET a 280z! (only grey imports.)

Looks like HLS30-172767 is now up for sale on Craigslist. The seller provides a lot of good information about the car's European background. The seller still has the car's original L24 engine set a side and the car currently has an L28. Here's the link: https://phoenix.craigslist.org/evl/cto/7559020402.html
