@S30Driver isn't this the same part you and I talked about a couple of years ago? Didn't you figure out a workaround somehow? I apologize if I'm way off base... thanks. Cliff

I've looked for a few minutes and found nothing definitive so I got bored. You might find something in these threads? https://www.google.com/search?q=greasing+240z+steering+rack+site:www.classiczcars.com&source=lmns&bih=606&biw=1280&rlz=1C1BOFA_enUS494US494&hl=en&ved=2ahUKEwjM1-uVpIfqAhWbG98KHUKeDQMQ_AUoAHoECAEQAA

My 9/76 has the 5 speed with the emblem on the rear hatch. I've never seen a '78 without a 5 speed but wikipedia says it was an option that year too. "In late 1976 and for most 1977–78 models, an optional five-speed manual transmission was available alongside the four-speed manual and the three-speed automatic options. It included a "5-speed" emblem on the left bottom edge of the rear hatch."

It can't be too bad, no broken head bolts. Seems like I've broken at least one on every junkyard motor I've bought. I'd keep it for now if you have the room. Scrap it when you get your other motor in and running.

They used to cost about $10 so for maybe $15 I'd buy a new metal filter that goes up front before the fuel rail, passenger's side fender. Hacksaw it in half and see what you find. I very much doubt any crud would get past that filter and make it to your injectors. The tank liner I used was Red-Kote and you would see red slivers in that rear clear filter. That looks more like trash to me? Anyhow it shouldn't leak if you have it right out of the tank, before the high pressure fuel pump. You wouldn't want that after the fuel pump's 35-ish psi output in my opinion. Others will chime in later about your ignition overheating. That's the 2nd issue you could have off the top of my head. Good luck.

I've had crud inside my fuel tank that would let them run intermittently like that, it's a real pisser. Put a clear filter coming out of the tank and see what you have. Good write up here, http://www.atlanticz.ca/zclub/techtips/fuel/g3filter/index.htm

Here's a nice chart on the different cams. Looks like the "M" has the lowest duration. Thanks @240260280 http://www.240260280.com/legacy/techtips/cam/index.htm

Here's some info on bigger throttle bodies. I've always read about 240sx TBs on 280s. https://www.google.com/search?client=ms-android-americamovil-us-revc&ei=LRPkXtafM6LhxgGAlZvwDw&q=240sx+throttle+body+classiczcars.com+&oq=240sx+throttle+body+classiczcars.com+&gs_lcp=ChNtb2JpbGUtZ3dzLXdpei1zZXJwEAwyBQghEKABMgUIIRCgATIFCCEQoAEyBQghEKsCMgUIIRCrAjoECAAQRzoCCAA6BggAEBYQHjoICAAQFhAKEB46BQgAEM0CUKcXWNY1YMdAaABwAXgAgAHIAYgBqAaSAQUwLjQuMZgBAKABAQ&sclient=mobile-gws-wiz-serp

My Dad had a hard time with my 280 when I was younger. The firing order was different from what he was used to. Maybe your guy has it off too.

I had a hard to figure out problem with a '77 I'd bought. After a month or so I read about a recall on those with egr. My egr tube had come loose under the intake manifold where it connects to the egr tunnel. No telling how long it had been like that but it had rotted out a hole as big as a golf ball under there. Take a handheld mirror and look under the manifold close to the windshield end. Happen to me so it's a possibility. Good luck.

Won't the overfill come out through the vent anyhow? He'll know it's full when there's a puddle.

Dr Dave did you use a bench mount buffer with the paste? Thank you.

Mine is twisted all the way counter clockwise, I think like you're saying with the tighten down bolt on the right. That's full advance to me. They run good at full advance IMHO. Check the plugs after driving it for awhile. Good luck!

When my clutches drop like that it's usually the slave cylinder. Nissan pickups, BMW 325 and an old ZX are my only experiences. No warning either, just dead pedal. Crank them over in gear to get off the roadway

Sale 1 Pontiac for $400 then buy twenty $20 car covers.

This is one of my favorites. http://jdmchicago.com/wp/2012/10/christine-siepkas-1978-datsun-280z/

This is close. They may have options? https://pandemusa.com/products/pandem-datsun-240z-s30

More Seinfeld, less current events. Thanks CO.

It's adjusted to that poster! Guy knows what he wants to see. I think one for your office is next? It looks fantastic!

I apologize. I meant read empty sooner. I've had a mind melt down over the past few days.

Simple choice for normal people. Not too clear for sadistic minds.

I had a kitty once that loved to pull at the threads on my car cover. She was good at keeping the varmits out of my engine bay though. Now I have a black snake. Maybe he ate the kitty? Circle of life.
