  1. Am I the only one doing anything to their truck? Anyways. New radiator. The old one was the original. It was literally crumbling at the touch. The radiator shop had to get a custom core made. $390 - ouch. Also new clutch master cylinder. And ... new glow plugs. It feels like a brand-new rust-bucket.
  2. I'm hesitant to reply to something so old, but there's no response. "wheel" or "tire" size? The rims are 14". The original tire size listed is an obsolete tire-sizing system. I've had good luck with these: LT195/75R-14 Yokohama Y356 D
  3. Isn't there a module with a bunch of coils providing various levels of resistance for the different fan speeds? I'm sure there is. Mine were all burned out when I bought my 720, which made me think if was something else. I bought a brand new module, and it worked great. The resistance coil for the highest blower speed is already burned out again.
  4. Replaced the corroded wiring for the right turn signal. New Green with Black Stripe all the way to the "lamps". And replaced the corroded bulb sockets that lasted about 6 months with LEDs coated in epoxy. Here's the PCB half-populated. I now don't have to contend with randos waving back at me every time I signal a right turn.
  5. I felt like I was thrashing my 720 with the SD22 on the interstate, 50 miles each way to work and back, trying to not be run over. I bought a Burgman 400. The Datsun lives as a result.
  6. Driving through Ohio in my Datsun a few years ago, going from Tucson to Syracuse, was not fun. I tried to avoid being in the cities during rush hour, but it made no difference.
  7. Having the piston at TDC was enough to keep it from disappearing into the abyss. I used a valve-spring-compressor that turned out to be handy.
  8. Interesting. I thought you could get power steering or air-conditioning, but not both. Talk about luxury. Also, I just drove the pickup around the block. Your trick of taking the glow plugs all the way out and feeling for the air flow made all the difference. The old seals were quite visibly larger in diameter around the valve than the new ones. It wasn't quite as messy as I was expecting. None of the springs popped off back into the pockets of oil. Now to see if it uses less oil. Thanks again guys! I lurk here but rarely have anything useful to say.
  9. Thanks Wayno! That bottom pulley is the one I have.
  10. It just occurred to me to look at where the exhaust and air intake ports are on the other side of the head. Presumably, these correspond to the exhaust and intake valves.
  11. OK. I'm stumped on this. I want to find TDC for a cylinder, but don't have the timing marks on the pulley. So, I should be able to tell when it's near TDC by the movement of the valves' push rods. I just can't figure out which is the intake and which is the exhaust for a given cylinder. Sure wish my pulley looked like the one in the book.
  12. My wife offered to hold it for me. We'll see how that works. So far, I've loosened the glow plugs, thinking I'll want to turn the engine at some point, removed the valve cover, and cleaned a lot. Mostly cleaned. I didn't know the engine was blue. I'm about to see if I missed something in the manual I have on what to do next. I have guesses, but not a head gasket. If money were no object, something like this could be fun: https://www.jegs.com/i/JEGS+Performance+Products/555/3010/10002/-1?&mrkgcl=1239&mrkgadid=3338000898&adpos=1o3&creative=330726016703&device=c&matchtype=&network=g&jegspromo=nonbrand&gclid=CjwKCAjw7anqBRALEiwAgvGgm83wxtvXXlPrko0OCznorX9seek4oA4XIQFKRseUH_9Zr8H373bSrRoCyacQAvD_BwE&gclsrc=aw.ds damn that long link. bad millenial web-scripting.
  13. Is that a trick question?
  14. Thanks for the help. I know it's not going to be a simple and quick process, but it needs to be done. That oil isn't cheap.
  15. No oil spots, just some rust flakes every now and then. There is smoke after adding oil.
