  1. Past hour
  2. My 9/76 is HLS30 355834. That looks like 901659 but my eyes are a little worn. Maybe it's 301659.
  3. Here is the engine plate. I won't have the door jam label until Saturday when I take physical delivery.
  4. Can anybody read this? Good data right there. Engine serial number, etc. Build date is on the door jamb tag. Lots of highly suspicious people out here. Nissan made mistakes on these cars, but it looks like it what the guy says it is, to me. Why are the intake manifold bolts orange? OMG, it's been molested...
  5. ZCCA judged show. Nice having this inside with AC.
  6. Today
  7. It might help your thought process to realize that the head "gasket" is actually three gaskets in one. The metal cylinder sealing rings, the copper oil passage sealing rings, and the composite water passage sealing material, that also positions and holds the other two seals together. Consider each one separately.
  8. Datsun Garage is proud to partner with Watanabe Japan to offer Watanabe rims to Datsun Enthusiasts! Only $100 deposit per wheel, any factory size available as well as custom features that can be done. Feel free to check out our website and info regarding these rims. Here is some more info: ALL NEW!! Available direct from Datsun Garage through Watanabe Japan. Available in sizes listed in chart. https://www.datsun-garage.com/shop/universal/watanabe-type-r/ All wheels are made to order in Japan. Because of this, lead time can take up to 3-5 months from the day you pre-order until delivery depending on production schedule. All pre-orders for R Type wheels require a deposit per wheel. Once deposit is acquired we will email you with a questionnaire. Once filled out with your specifications and full payment is made we will place the order with RS Watanabe Japan. Please reference the chart for more information regarding the wheel and our website for more info regarding pricing. It is not an exaggeration to say that “Race model” R Type wide rim minus offset, although it is difficult to get a little with current car, representative model of Watanabe that leaves history in numerous records and race scenes https://www.datsun-garage.com/ Contact: sales@Datsungarage.com
  9. OK. Thanks for the details. Got it. I did not see the top rivet on the pickup (5). I just did this adjustment on a similar set up and the pickup would move when turning the eccentric (3). It seems yours is not adjustable without drilling a rivet.
  10. Here lately a brake boosters are getting hard to find on the east coast.
  11. I can't imagine you letting the wiggle go un measured.... :) snorkle need a procedure. If you come up with something I will try as well. I suppose a way to measure the bore would be best a series of go no/go round gauges would be best for the bore.
  12. I think a short voyage is a better idea!
  13. @Captain Obvious attached below is schematic with details of FA6004 audo amp in 1972 portable Hitachi radio. Same 8pin SIP module. It may be similar in some ways. The best I can do. FA6004 Details.pdf
  14. The strange thing is that the same username is over at Zcar.com with similar types of posts: https://www.zcar.com/search.php?searchid=50972
  15. All of the valves wiggle a little bit, but yes, I've found that the exhausts wiggle more than the intakes. I'm not going to measure them, because then I'd know. I did measure the lengths of all the exhaust valves though, and found one that was twenty thousandths shorter than the rest. No idea why it's like that, but that one did not make my set of the six best exhausts.
  16. No. That's exactly what they would they expect me to do. What I'm doing instead kinda goes like this. Under magnification and with the use of some sharpie marks on the sealing surfaces, I've tried to match up the correct valve with the correct cylinder. And then after that, I'm lapping them to match the seats. For example... Here's one of the seats before I've done much of anything to it. The valve that WAS in this location wasn't even close to making contact on most of the seat. I managed to find one of the other exhaust valves that was pretty close. Here's what I'm starting with: Here's my handy-dandy valve lapping "tool". I use double back sticky tape to hold the valve to the "tool": Some 800 grit lapping compound: And I work the pair: until I have something like this. Smeared contact markings over the entire seal: Yes, there are still a few pits on the valve seat, but I'm not looking for perfection here. I'm just looking to be able to drive a little bit more on this engine until I finish the F54/P79. What I'm ending up with is 1000 times better than what I started with!!
  17. I bravely swapped bad unit's output stage to working unit and it continued working. I put working units output stage in bad radio an no change. I then moved good AF SIP to bad radio and it worked... risky but easy. I did verify all voltages in power transistors were the same before swapping so low risk in the end.
  18. OK, I marked this up so its a bit more clear... Dizzy by blodi, on Flickr 1 and 2 hold the pertronix plate (4) to the dizzy plate (6) and it cannot move around from there. I can move 3 around a bit, but it can't move 4 at all. 5 is fixed to 4 with rivets. 7 and 8 both did need to be snugged down a bit. What I did last night is removed 1, adjusted the gap and tightened down 2. Not sure if it will hold in position with just #2 in place, but it allowed me to open the gap.
  19. Yup! I Got it! Haha!! So not that it really matters, but that's an AF (Audio Frequency) amp, not an op-amp. Good luck with the repairs. I paid my way through a couple years of college fixing audio-visual equipment. One of the things I learned is that 95% of all failures are blown output stages. Even if the problem does not appear to be a blown output, it might be anyway.
  20. Sorry. I corrected entry but left the wrong right in. <<< makes sense right? Fixed now. Sorry. No I do not have data sheet. I would love to see it too I think the IC is more than just an op-amp as it feeds back to the auto tuning circuit. See Pin 7's output below. I will guess that the op-amp function can be substituted with a compatible op-amp but you will loose the auto tuning without developing the associated circuitry to trigger an amplitude lock on a signal or maybe it is a mute while tuning control?
  21. When I'm using sealer, I almost always use a syringe to put it down. I've found that less is way better than more. Without getting into whether you should have used it at all (or not) on a head gasket, I think you used way too much. @Locke Glad to hear you're starting over. I'm needing a head gasket sets for my upcoming projects. What was the Stone number on that gasket set?
  22. dusty snorkle (there is that word again CO). Clean undercoat and heavy dust on top. Seems to support the idea of something new that sat undisturbed for years. Crud on pedal, drove it in garage, never looked at it again. Very interesting. OP if you can get some video.
