Here's the recall explaining it somewhat. Wick Hubble's book explains in depth, page 194. https://howtune.com/recalls/nissan/280z/1977/

Here's the latest routing too. 1978 changed to this...

I've always considered this little gap as a way to connect the valvetrain and the crankcase. I got worried about blowing out the rear main when I first started fooling with a rebuild and removing stuff. We don't do the smog test here. The yellow circle in this google image. That's one without the front cover. The head hangs over too so it's an open path from the valve cover to the oil pan, in my mind.

Agree with what was said above. That book will walk you completely through tear down then rebuild yourself. There's a few things you have to take to a machine shop and get done but I got out cheap there, about $200 if I remember right. Take tons of pictures and write everything down you may not be sure about. A roll of cheap painters tape was a big help for me on the connections, wiring and plug-ins. You can do both sides with a piece of tape then add 1 & 1 or A & A. Get a box of quart size zip-locs for all the nuts and bolts then write what it is on a piece of paper then drop it inside the bag. I wrote on the outside with a Sharpie, bad idea as it smeared off. A gallon of lacquer thinner and some small brass wire brushes for cleaning from your local hardware store is about as cheap as you'll find. Cheap spray on oven cleaning foam also works good. It's like $.99 at walmart. A few 5 gallon buckets will be useful too. All 6 pistons fit perfect in the bottom for me, poured about 2 inches of lacquer thinner in there and they came out like new. Read, read and read. You'll see something helpful every time, have fun young man! Here's a days worth... https://www.google.com/search?rlz=1C1BOFA_enUS494US494&ei=ueSNXvXSLrCwytMPxNeXiA0&q=l28+rebuild+parts+list+classiczcars.com&oq=l28+rebuild+parts+list+classiczcars.com&gs_lcp=CgZwc3ktYWIQA0oJCBcSBTEyLTc1SgkIGBIFMTItMTNQqKsBWP7KAWDq1gFoAHAAeACAAWSIAbsHkgEEMTIuMZgBAKABAaoBB2d3cy13aXo&sclient=psy-ab&ved=0ahUKEwi1k876idnoAhUwmHIEHcTrBdEQ4dUDCAw&uact=5

I'm still unsure how it came about, not that it matters now I'd just like to know. Natural or engineered? Will we ever know this, can it be proven? I know my 240 wouldn't run more than 5 minutes because of the crud in the fuel tank. Once I figured that out I fixed it. If this virus has no definite source how can it be fixed? I'm ignorant, not stupid so laugh all you want but 90% of the world is thinking the same.

I edited that just now and you are quite welcome.

Early Zs had 7". In '73 thru '78 they went to 8.5". I can't see an auto using a larger booster but I've never owned one. Go to amazon.com and use their "will it fit" tool.

How do you get the 14mm from the bottom? Edit. I'm sure it's just proper math. Please disregard.

How are you John? You can help me and some others with your experience. I don't know pollen OD from covid 19. Mowed grass Friday and woke up Saturday feeling like crap. Scared me! Cliff

No good... Better...

Bend it down towards the float for more fuel. Make it look like speed bump. Not a ramp.

What about microwaving a mask, would that work? 2 minutes maybe? Thanks for any input. I don't have an oven.

Just had to run an errand for Mom. I panicked because I've not made a decent mask. I did however come up with something I'm pretty sure everyone has. I have a drawer full from reckless lifestyle. ACE bandages! I had a couple that were 6" wide, knee surgery. Wrapped one from below my eyes down to cover my chin. Worked great!

The fuel in your tube should be level or even with the top of that rectangular square in this photo. The green arrow points down to a red line on bottom. In between 2 red lines that say "23mm". The lowest red line in that photo.

Yeah yeah I know..."Logic". Some made up word my Grandfather used to talk about during the Old Days. Like "Daylight Savings"???

Hows @Av8ferg today? I sure hope he got better and not the virus.

It's one of these or my old full face motorcycle helmet.

2020's Moral Insanity...EGO.

I bought mine at Advance with a coupon code from retailmenot.com for 25% off. Buy online and pick up at the local store, if they have it in stock, 10 minutes. $20 is what I paid about 10 years ago so that says something about the reliability I guess, it still works great. Could be I'm just lucky. Nah, that can't be right.

That guy is nuts! Just scolded some girl for being nasty. Hello pot, this is kettle and you're black as s h i t. He gets off on calling detractors stupid but hateful nicknames.

I hit that age way too soon. My to do list has priority numbers that have been scratched through way too much. Glad to be where I'm at in life.

Yeah that looks bad. Can you smell fuel from a mile away?

Your written description would be good to me, better than videos anyway. Tell us more. Is it worse with pressure on the shift rod or better? If it's simple as the rod worn out applying pressure would quieten that.

You familiar with the performance improvement plan? I had to google it.

That's what I consider bullying. I have to deal with it almost everyday and it's exhausting.
