Nomads Problem Thread.

[Nomad707]

Ok.. sorry for making this complete halfass thread... i searched breifly for how to disconnect the fuel line.. and didnt see anything..

I dont want to mess anything up so im just wondering how i should disconnect it.

I might have other problems today as well which is why my title to this thread is generic.

Forgive my repeated questions, i just donated 7.77$ under deadpirate87@hotmail.com alright guys thanks for the help as always!

how to disconnect the fuel line

Well seeing how there are a half dozen fuel lines on a MK3 supra, I'm assuming you mean the fuel line(s) at the engine/fuel rail. The feed for the fuel rail comes from a banjo bolt near the driver side motor mount, its a hard line. You need 2 new sealing washers if you take that banjo bolt out. The return is a rubber line that just has a clamp holding it to the return hard line that is bolted to the drivers side of the engine about 10 inches below the intake manifold, right above the oil pan gasket. Take those 2 off and you will be able to remove the fuel rail, injectors and lower intake manifold.

ok i got my head off, new hg on, head back on, and everything now is in place... ready to start.. but my EGR valve, where it connects to the lower im/head.. is broken.. what would happen if i ran the car without the egr valve and without blockoff plates? (no money)

With no EGR and no block-off plates it would run lean. At least find some scrap metal grind it down drill some holes use some RTV at least. No reason for putting your hard work at risk.

thanks..
can someone give me the measurements from hole to hole if i was to make a plate? and what size should each hole be? (for top and bottom I/M)

 

[Nomad707]

anyone know where this leads to and what it connects to? i have the other end of it and its disconnected.. i cant see where it goes.

thanks.

Only thing I could find, hope it helps...

 

[Nomad707]

bah it just leads to nothing in that diagram... crap.
anyone else know where it leads to? or what it goes to?

 

[supramike7m]

thats all bro, its just a vaccum source for emissions crap, vsv.

 

[Nomad707]

if i leave it unplugged am i looking at something threatening?

 

[cactus_mole]

just hook it up like the diagram.....this is your chance to do it right. I remember when I saw it, it was a fucked up.

no dude look... THIS part right here.. has a hose on it that doesnt connect to anything.. and it doesnt show it on this diagram.

see the arrow?

no way, its just for emissions crap. nothing threatening

 

[Nomad707]

ok and last question.... running without an egr and no blockoff plates will run me lean? i just want to make sure... if so then i wont start it untill i somehow get 2 blockoffplates

 

[cactus_mole]

no dude look....the one on the bottom connects with the one on the top then to your by-pass valve.

remember when we were looking at it and I said you didn't have the hose coming up from the bottom of the intake...this is it

 

[Nomad707]

hmmm... ok

lol. ill hook it back up

Shhhh......Im hunting a "I shouldn't be posting" poster here......

Running with no EGR wouldn't cause you to go lean.

Running with out the EGR exhaust port plugged would cause the car to be laggy due to a major exhaust leak.

Running with out the EGR intake manifold port plugged would cause a boost leak and the car to run RICH.

thank you for elaborating.. now to try and plug them. lol.

 

[irocznissan]

vaccum leak man. plug it with something. ebay has a blocker kit for like 10 bucks or so

Under boost, but at idle and vacuum conditions it would run lean from un-metered air entering the intake manifold.
