Topics Last Week

When I said repros, I meant whatever is being offered on the aftermarket today. I sold my rusted originals for a pretty healthy price. I always figured the ones I bought were genuine. BTW yours came out great, that's the goal for mine. Very tastefully done.

I've been playing around with the free AI the last week as it's scorching hot down here and everywhere else too. Anyway it's pretty neat plugging in numbers and seeing the supposed results. My main goal is to eventually figure out my P90 head I bought for $25, yeah that's right twenty five dollars 😁, hopefully what valve length and lash pads I'll use and how much to cut for the Schneider cam kit I bought many years ago. I don't think it's my cam though, just a core I sent in but it has high lift so I'll be using the Viton Ford valve seal as the OEs would get squished. @Diseazd has given me some advice also to go along with the P79 and P90 modifications Datsun garage provides. https://datsunzgarage.us/p90/

Nice Zed, it's a famous number often played, this one is also a good choice... OZZY OSBOURNE - "Mama, I'm Coming Home" (Official Video) - YouTube

Newer but pretty cool!

It seems that's what you've been doing for the last decade and really aren't any closer to a solution than you were when you first recognized the problems. Unless you have a strong emotional tie to your Z, I suggest moving on to another car that you can enjoy driving with confidence that it will run well and get you where you want to go and back home. Just a suggestion that could make your life less complicated and more enjoyable. I once had a '74 Porsche that I never drove farther from home than I cared to walk back. I knew several AAA tow truck drivers by their first names. I was happy and relieved to finally sell it and eventually bought another that I've owned for 32 years.

He didn't but these guys did.

@Nils Ya, when you press the switch it's supposed to flip into the other position. It sounds like you have a similar issue to what I had originally: I could depress the toggle, it would temporarily switch to the other side, but once I released the switch it would reset back to the original position. Yours sounds a little worse as it isn't even able to temporarily switch. I forget which colors correspond to which, but power comes in through the center connection, and then goes out through the connections on the left or right - one for high beam, one for low beam. Ie, we'll just call the connections 1, 2, and 3, with 1 being high, 2 being the center, and 3 being low. 1-2 would trigger high beams, and 2-3 would trigger low beams. You can test that with continuity. You should never have continuity between 1 and 3. @fredrick that's a spring and a brass cap. It sits in a circular opening in a rocker inside the actual switch housing. The piece is held into the plastic via a roll-pin and is the only part I didn't remove when disassembling the whole thing (I didn't think there was a chance I get it out without it breaking. It's the second picture in the first post This whole setup is quite finicky and I've thought a few times about trying to engineer some kind of replacement, but not sure if the interest would justify it.

I will double check that but I don't believe any of that has been changed since my last test fire. I did remove the combo switches and reinstall. Maybe I messed something up there

@solly I don’t believe you answered my question about the check valve. Trying to offer known problems that cause what you are describing

Called a "reaction disc"

It's always a mistake to paint/powder coat those rear stub axle brake drum flanges, Nissan didn't.

Well you do! You have an excellent camera.
