Ebay $100
heres what i get (pic)
I also ordered new plug ends for the injectors for $20 and 8mm yellow accel plug wires for $10 off ebay

wolf66

triing to figure out what those rings are above the injectors, don't see them in this diagram, and looks like i need to find my old heat shield gaskets

AllmyZs

They might be some kind of locking washer. Let me know when you piut them in.

wolf66

wonder if i can get the heat insulators any where or make my own.

AllmyZs

You should be able to make it out of exhaust gasket material. Check with a local parts store. Just use an old one for a template.

hey in my thread over at zcar.com they said about the valve cover breather to hook it to B, which sounds right cause thats line that did not have the air reg on it, ie the one that vented all the time

AllmyZs

That si right look at this pic. in your post at 240,260,280 performanc techincal an page 2. It is a very nice pic. That is where I ran mine to. I figure on the fuel just run a vacumm from the vent to the fuel return line or just cap them.

wolf66

yeah that is B he has it hooked to on that clean motor.

On the vent if you mean the charcoal tank vent. you can't cap it, your fuel tank has no other vent and needs one.

AllmyZs

What about a breather filter? Think that would work. Or do like you said and run a line into the air intake.

wolf66

Problem with the breather filter is you will still smell some gas fumes sometimes if the engine dosen't suck it in, thats why i want mine dumping next to the air filter

AllmyZs

I like your Idea better. I will try that tonight when I get home. I will let you know hor it goes.

Did the injectors today, those black rings are the ones that go around the middle of the injectors.

The exploded view of the injectors i posted above from the Haynes manual is wrong, the part labeled #2 is backwards in that diagram, if you try it their way the bolts won't even reach.

She started up and ran but has a high idle thing, will play with it tomarrow and see whats up, might be the cold start valve stuck on, need to make a plate to cover the hole.

I did have the heat shields on the old injectors but they were installed at the top instead of the bottom and probaly fried the old ones.

AllmyZs

Nice glad to hear that she runs. I didnt work on mine last night it was -5 so I was to dam cold.

wolf66

OK , she runs like the well oiled machine she is now!!

Turns out the idle screw was backed out all the way, while you screw it IN to lower RPM! The idle was normal before because of all the vacuum leaks.
Got rid of all the stuff i wanted to, here's a before/after shotof the engine. She hadn't run in 7 years!! Its so sweet to rescue a beautiful auto.

wolf66

here's a close up, i hid all the holes from the crap i took off with shiney little screws.

wolf66

On the right wall i took off the charcoal cannister, the AC vacuum tank and selinoids, on the motor i took off or disabled the BCCD, the air reg and line, the ERG and its other little tower and lines, the lines to the charcoal cannister, the AC fast idle and AC belt, and the stock air box,the vacuum switching valve(tranny controled advance), the dash pot,and the BPT valve.


I ran the air vent for the gas tank over the the air intake/filter.

wolf66

By the way, if you scap the charcoal can, DO NOT hook a vacuum line to line that is left, its a vent for your gas tank and needs air for the gas level to drop. Thats why mine is vented near the air filter and not hooked to the intake boot as you had said.

AllmyZs

Nice, thanks I will get mine done hopefully today. I will let you know.

AllmyZs

I took off all that smog stuff. ran the vent line out by the overflow bottle, removed the choke and the car fired up without any issues even in -3 degree weather. It idles a little low when I first start it but after I let it run for about 5 seconds it goes up to 750 like it should. I do want to know did you remove the water junction that is mounted on the intake manifold under the fuel rail? I am thinking of just taking it out and route the tubes together. Let me know what you think. I see that you primered yours. I am going to leave mine polished. It is going to take a little work but I think it is worth it.

wolf66

I am going to remove that part, (thermal vac valve), right now it is pushed up over the edge near my radiator, figure like you said, i'll cut and splice it will a small section of pipe and hose clamps.

When I do take the Air Intake manifold off i will get it bead blasted for sure but it was painted a wierd blue when i got it and it hasn't been off yet (didn't look like any fun, hooking the new clutch master cyl to the pedal was hard enough, lol)

Just got a 1977 Datsun Brochure off Ebay today, here's the stock 280z shot:

AllmyZs

Nive PIc wish I could find a set of those rims.

wolf66

Yeah i partly bought it to see what the stock rims were too, everybody seem to have Aftermarket, from what i have read, most left the dealer that way.
