    This is the original fascia nut and odd looking squarish washer that came out with it:

    One of the captive nuts on the fascia on my car was stripped out so to fix that I made my own captive nut by cutting a rectangle shape out of a repair metal from Thrifty hardware and drilling and tapping it for the 4MM original machine screw. I used a bench grinder to make the new nut have the same size as the original and to have the beveled edges the ...

  2. Rear frame rail interiors anti rust spray

    Hi all,
    I sprayed all interior channels of the rear frame rails and interior of wheel wells of a 240Z with two cans of Transtar amber anti corrosion material using existing holes where possible. The front frame rails are more likely to rust but I had already sprayed the interior of the front rails on my car. A thread describing how I did the front frame rails is here:

  3. Turn switch relay mod

    Hi all,
    I added relays to the turn switch to take the current load off the switch by copying the idea on the website below. The mod is reversible and by doing so will leave only hidden soldered wires inside the clamshell as the only evidence it was done unless holes were drilled to mount the relays. With this setup the heavy current still flows through the fusebox but only a small current flows through the turn switch itself. I followed this website posting but I used a different brand ...

  4. Heater blower motor squeal stop

    It is possible to lubricate both blower motor bearings without taking the motor out of the car to stop squeals or other noises related to motor bearings. I realized this after I had taken the motor out to lubricate the bearings. Many have opted to replace the existing blower motor and fan with a Honda civic heater fan. I like to fix things so I oiled the old motor because it was turning slowly and was squealing.

    Here are pictures of the firewall insulation of a 1/1972 240Z on a "fabric board" with lines 1 inch apart going both ways to allow duplication if for some reason someone wanted to. Note that the top edge of all three pieces of the insulation are lined up with a blue line on the fabric board. Pictures were taken in full sun and have shadows. To clarify where the black insulation poster board ends and the shadow begins white dashed lines ...

  6. Throttle jerk fix

    Hi all,
    This mod eliminates MOST of the throttle jerk but not ALL of it. I owned the car for 4 years before I noticed it still has a small amount of throttle jerk. The previous owner of my 240Z reduced throttle jerk from idle to take off by bending the upper arm of the "turnstyle" as seen in the attached pictures to a stair step shape effectively shortening it. This mod is no cost, possibly reversible and requires no welding, drilling or adding parts. The connecting rod ...

  7. Cowl leaf screen

    This mod is reversible leaving no trace. Using silicone rubber sealant I glued a piece of aluminum window screen I spray painted black onto the bottom of the cowl where the holes are to keep leaves and other debris out. The screen helps prevent corrosion from debris trapping moisture in the area where the windshield wiper motor is.

  8. Hood emergency release (plus handle mount stripped threads fix)

    Hi all,
    This has been done before by others, the following is my experience. I added a second hood release cable so now I have two of them in case the original cable breaks. Getting the hood open after the cable breaks is not particularly easy in my view of how others have done this. The easiest way to do this IMO is to do what someone else did, loop a steel wire through where the original hood release cable attaches to the latch under the hood, run it through the firewall grommet for ...

  9. Scion FR-S and Z

    As far as affordable, lightweight, and fun to drive sports cars.... did the venture between Toyota and Subaru beat Nissan to the punch with their FR-S?
    This car looks so much like an old Z, I'm beginning to wonder if the rumors around a new 240z are going to show up with a car that looks a lot like the Scion FR-S.

    C'mon Nissan, you've got to do something good for this market!

  11. Clock replacement for 240Z (Quartz)

    Hi all,
    I got a quartz clock from Michael's (arts and craft store in USA) and replaced the mechanical clock mechanism in my 1970 240Z (my clock face says JECO). There is a thread where someone else used this same clock for their Z, the following is my experience. The easiest way to do this IMO is to use the hands from the new clock and to wrap wires onto the new clock battery connections to remote the battery location to perhaps the fuse box. I didn't install that way as I wanted the ...

  13. Access door for fuel vapor hose

    Hi all,
    I put in an access door for the large fuel vapor hose that connects on top of the back of the gas tank making it easier to change out the hose. After dropping the tank to change that leaking hose I realized I wanted easier access to that hose though I recognize it might be a while before it needs replacing again. I figure anything that makes upkeep easier prolongs the life of the car.
    I put an aluminum rod approx 1/4" DIA about 10 inches long into the part of the ...

  14. Gas Tank sealing with POR 15 standard tank seal

    Many thanks to Jeff G 78 and postings by others for help with this. I noticed the instructions on the standard tank seal can called for thoroughly stirring the tank seal which I thought I had done but when I poured the seal in the tank there were a few lumps. If you look closely at the flat surface on the right (tank baffle) in the completed picture below you can see a couple of small lumps likely from lack of stirring. I used a pint and a half which is a half pint more than what POR says you ...

  15. Hatch anti corrosion interior passageways

    Hi all,
    I went to spray the interior metal passageways of my 240Z hatch with a Transtar Amber anti corrosion spray can and noticed there is a reinforcement plate on both sides and top of the hatch. To spray the two passageways created by this plate on the sides was easy as I just had to guide with my hand the 3 foot long spray wand above and then below the reinforcement plate as you can feel the end of the plate with your hand. See drawings. After I did this on both sides I drilled ...
