    Bought by us in Dec 2017 from the 2nd owner. Very original, zero rust car that lived in Bakersfield, CA for 41 years and Paso Robles for 3 more. Now resides in Irvine, CA. <br /><br /><br /><br /><br />
    -- Car is mildly cammed, with a lighter flywheen and a shorty exhaust (terminating under the driver). Runs strongly and will be a daily driver. Lowered about 1.5". Plenty of little things to upgrade/restore over the next years.

    Not that I did but if I did, then what?

    Update: After visiting the local police department and having them tell me they can't sign off on exhaust - I'd need to go see the CHP, I did just that. CHP officer gave me a little bit of a hard time about my header, little filter on my breather, etc., but he recognized that my '72 is pre-smog and let it go at that. Then, he asked me to start 'er up. After listening to the idle for a couple of seconds, he asked me to rev it a few times. My silencer did the job and he said "Sounds like it should be fine". He signed off on all three of my issues (brake light, front plate, loud exhause) and I was on my way. Whew! I'll try to get around to posting a before/after silencer video soon.

    Actually, those look so cool I think I'll put 'em on the OUTSIDE of the exhaust pipe!

    @charliekwin Thank you. I just looked at the links and looked around online for the exact test procedures. I was getting a little scared that they were going to put the car up on a lift, shine a light in, position a microphone, make me rev it to 3/4 full throttle, etc. But I just called the police department and they said I can just bring the car to their station. An officer will inspect the car and sign off on the ticket, which I will THEN take to the courthouse. I'm hoping that if I do it that way, it'll be casual and they won't do a dB test. I'll let you know how it goes tomorrow...

    Not that I did but if I did, then what?

    All good points, guys. I really don't know how the car would do on a dB test - I'm just saying it isn't crazy loud - not as loud as most Harleys or most WRXs or Mustangs in the area. It gets loud at higher RPMs (a bit cammy) but idles nicely. It DOES have a muffler on it - it's just a pretty free-flowing one. A bit louder than a Flowmaster or Magnaflow. I'll try to video it later. By the way, this "silencer" will be inserted about 10" into the exhaust pipe and held in place with a little screw from the side. This is not an add-on tip. They won't see that paint the way it shows in the photo. The original reason for being pulled over was the brake light not working. My son was driving. The cop added the missing front license plate and "modified exhaust" during his walk-around. The other two issues are now fixed (more on the license plate issue later). I wouldn't be surprised if a reasonable cop wouldn't have had an issue with the exhaust. I'm just trying to hedge my bet.

    Brake light (switch?) question

    Gents, I just realized that I didn't close this issue out and I should have. After talking to him, I sent the turn signal switch assembly up to Zs-ondabrain. He had the switch back in the mail the same day (total turnaround including shipping both ways was less than a week!) and my problem is solved! I had my kid install the switch and everything works perfectly. I NEVER would have come up with this solution on my own, so I really appreciate all of your great troubleshooting advice, and especially Dave for his skill and great customer service. And on a side note, I want to express how grateful I am that buying this car (and being involved in this forum) is giving me a way to both learn and to teach my son how to work on things himself. I'm a handy guy but have very limited auto mechanical experience. We live in a neighborhood where few of my son's classmates could find the spare tire - and NONE of them could change it, let alone do the other jobs he has learned to do. So great to see a kid turning wrenches - not just punching keyboard or video game controller buttons!
  9. Let's say that I, hypothetically...no, not me - a friend. Yeah, let's say a friend hypothetically got a fix-it ticket that included "modified exhaust" that the cop thought was too loud (it isn't) and needed to show up at the DMV to settle it. If that scenario ever presented itself and if this friend made a makeshift exhaust silencer (that works pretty darned well!), he might have the following question for you guys: "What, if anything is the danger of a substantial increase in back pressure to the engine over a short time/distance?". He is prepared to stop at a park near the DMV to install said device if it is better not to drive 8-10 miles round trip with the increased back pressure. Otherwise, the plan might be "install - drive - test - drive - uninstall".

    Brake light (switch?) question

    Well, I'm not going to argue based on my short phone conversation yesterday. Rod seemed to think that the right and left sides were handled separately in the hazard switch and that a failure there could cause my problem. He recommended some contact cleaner and simply flicking the switch up and down to potentially improve contact as a quickie remedy. I did try that this morning and it didn't help. So I guess the consensus is that the turn signal switch is the likely culprit, eh? I know Dave's an expert on the subject and he's been awesome to work with in the past so I'll go that route now and report back as to how it goes. Dave, I'll reach out via email. PS: @Captain Obvious, thanks for helping me to avoid running over to Motorsport Auto and buying a switch I didn't need. You guys are great.

    Brake light (switch?) question

    Thanks, guys! Dave, I talked to my favorite local mechanic, Rod Schmidt this afternoon about this. He also said I should take a look at the Hazard light switch, which is often the culprit. I tested the hazards after making my original post and I added the fact that they work as point #3 of that post. I'll make an attempt to play with that switch (switch it up and down rapidly and also try some contact cleaner) and see if that works. Knowing now that the hazards work, does it make you suspect the hazard switch over the turn signal switch? Rod told me today that you also rebuild hazard switches. Is that true? If I'm not mistaken, I think I turned Rod onto your service after you rebuilt both of my column switch assemblies. I think he used you recently, right? If I'm correct, then I'm glad - very happy to refer good people to your service, which is fantastic. I'll mess with the hazard switch and see if I can jar something loose :-) On the other issues, I'm planning to order a pair of 1972 blue/yellow CA plates from Dave's CA Plates tomorrow for $250. And for the "modified exhaust"? I'm thinking of taking the car "as is" after the lights and license plate have been fixed and see if a more reasonable officer will sign off on my exhaust, which really isn't that loud (at idle).

    Brake light (switch?) question

    Got a fix-it ticket for the right side brake light not working. I mentioned this in another forum post that was mostly about the exhaust (one of the other items on the fix-it ticket. No front license plate was the 3rd and final issue) Trying to figure out why the right side brake lights don't work and I don't know anything about electrical systems. Here is what I know: 1) They worked until recently. 2) The right side turn signal works (which tells me the bulbs are not the problem - the same bulbs are used) 3) The hazard lights work (same two bulbs on the right side as the turn signals and the brakes. 4) I replaced the bulbs with new ones, anyway. No change. 5) Left side brake lights are working. I wonder if the brake light switch under the dashboard is the issue? I can see that the switch has two wires coming out of it. Is one for the left side and one for the right? If so, that seems to be a likely culprit and maybe I should just replace the switch from Motorsport Auto (link to the page here) for $23 and see if that takes care of the issue. Anything beyond that will probably be beyond my ability to troubleshoot/diagnose. Any thoughts or experience that might help?

    Need advice on brake rotors for '72 240Z

    Gotcha. Yes, I think we have the knowledge with you. Brakes are sounding and working fantastically now. Thanks to the great advice from people on the forum and some elbow grease I think the front brakes are an item we can add to our knowledge toolbox. Sent from my iPhone using Classic Zcar Club mobile
  14. Attended a Datsun meet-up in Orange, CA today. Quite a few nice Datsuns/Nissans and around a dozen or so 240-280Zs. Ours is the white Z w/ black stripes. The strange beige car is a 1989-91(?) Nissan Pao. Sent from my iPhone using Classic Zcar Club mobile

    240Z brake light help needed

    I don't know much about electrical systems, so this might be a really simple issue for some of you but it has me scratching my head. And it caused my son to get pulled over, which resulted in a 3x fix-it ticket for 1) The brake light, 2) modified exhaust and 3) no front plate. Here's the issue: Right side brake light doesn't work. Some issues: - Left side works fine - Replaced the bulb. No change. - Realized that the same bulb is used for turn signal and it works performing that duty! - Hazard lights (including the brake light bulbs) are working fine. - It worked until recently - I will go through the fuses tomorrow when it's light, but I assume it shares a fuse with the left side, no? Again, the left side is working. Any thoughts/ideas would be most welcome!
