    Default Need Pictures of 100% Original 1970 240z Engine Compartment

    ^what the title says. I'm having my 1970 240z's engine rebuilt and everything in the engine compartment completely restored to factory. If anyone has a pictures of restored or perfectly original 1970 240z engine compartments, I'd appreciate it if someone could post some.

    What's the build date of your '70, Brad? There are some differences between early and late '70.

    It's a late '70, production date of 12/70.

    OK, that means it probably conformed to '71 emissions standards, so it would have come with the Summer/Winter flipper on the airbox, and without the "2400" cam cover. That would make it virtually identical to my red '71 as it was when I bought it, except for things like the '1971' date code on my original plug wires.

    The first 5 pictures are as it was when I bought it. The only non-original things visible there are the battery, oil filter and possibly the fuel hoses to the carbs. If you look closely at fifth picture you can even see the "1971" date on the #6 plug wire (near the top of the picture).

    The sixth picture is how it looks today. I'm not crazy about the blue NGK wires, but haven't done anything about that yet. The airbox stickers have been replaced, and all the coolant hoses are modern non-braid-covered. If you look closely you'll see a Pertronix coil and the wire to the Pertronix in the distributor, as well as a later plastic fan and clutch.

    The pictures I attached are fairly large to see best detail. Make sure you open them in a separate window.

    Thanks for those pictures. The one thing in my engine compartment that I'm not sure is original is the coil and resistor bracket. The resistor is in a bracket that clips onto the top of the coil. Was that design stock on a late 70?

    I'm not sure. I've seen the one you describe. But all three of my cars (from 10/70 through 7/71) had the resistor attached below the coil.

    It's still the original one that came with the car. I don't remember where I found it or why it wasn't in the early pictures. Don't know where you can find them today.

    Hey Arne, I was looking at getting a set of those blue NGK wires on eBay. Do you want to sell yours?

    I noticed the same thing on HLS30-00110, 12/69, the resistor is mounted on the coil bracket. It appears the steel fuel/fume/vapor line and valve(?) are mounted in the place that the resistor is mounted on the 73, below the coil. This makes that fuel/fume/vapor line about 7 inches longer than on the 73.

    I bought a replacement hose clip back in 2003 that I have in storage. The part number listed is 18762-H7900. Hope this helps.

    not refering to the hose clamp. it's the black plastic (becomes brittle over time) tie that wraps around the rad hose to hold the temp sensor wire from dangling into the fan area. a zip tie will do the job but it's not period correct.
    i have mine but when i replaced the temp sensor one ball on the end broke off. never though but i could have superglued it back on, now i can't find it.

    Check out Motorman7's 70 engine bay, he recorded on this site the restoration of his engine compartment and it is outstanding.

    I believe that's actually the later replacement style. The early ones didn't have the snowman shape on the left for lack of a better description.

    Enigma is right, the one I have does not look like that. On the one I have the left side is a way smaller version of the right side.

    Reference from post #17 above picture didn't copy to quote

    Kats website shows you the difference between the new ones and the old wire support their is a difference. I could not find the picture today but this is a great site I learn a lot looking thru the restorations. What you have it the later one, but if your not too picky it works great.

    If you want 100% original pictures you should go back to period Nissan publications, like brochures and the service manual. Here is the engine bay pic from the 1970 brochure. The car shown is actually an early 1969 production car. The stock resistor bracket mounts at the bottom of the coil, not the top, on 240Zs.
