California 280z "Voluntary Recall" WTF?

[sblake01]

ok i have the #1 config. and i'm while the car manual shows me the #3 config..

but i also think that it could be the #2 config with a cancelled hose that goes to the boot in front of the flowmeter..

but can anybody tell me where does the end of the hose on the junction which is against the valve cover end?? if the picture ws from the plan view it could be clearly seen!

thanx..

On my car, which is picture #3, it connects to the fitting on the throttle body, just to the right of the idle adjustment screw, as viewed from the front of the car. It also connects there in picture #1. Picture #2 has it ending at the rubber boot between the AFM and the throttle body.

Stephen, i gues that u got me wrong, it was hard to explain:)

i asked about the hose that is noticed by the red arrow in the picture, where does it go from the juntion that is under the valve cover hose on the #2 config?

if u have the second config. do u have a very strong vacum under ur oil cap? that u hear the air sucked to the engine while opening the cap??

[sblake01]

Sorry but I have config 3 so my car doesn't have that junction. I have a slight vaccum at the oil cap and when I remove the oil cap, the idle drops about 75-100 rpm.

California drivers who are going to be affected by the cancelling of the 25 year exemption would be better off remembering that changing the emissions system from what the car had originally may make it difficult to meet the standards to pass their emissions check.

I'm not sure of their methods of determining the different standards for each model / year, but I do know that a vehicle from 1975 is NOT expected to meet the standards for a 1999 vehicle. If it can meet or exceed the standards for it's model year then it passes, but I have heard that if the system is MODIFIED from it's original configuration (regardless of whether it passes the test or not) that that is cause for a "fix-it" citation.

Someone correct me if I have it wrong, please!

I remember this conversation coming up on another site (regarding the same 25 year rolling exemption) and being able to remove the Air Pump or not prior to the 25 year anniversary. The general consensus was that the system could NOT be modified prior to celebrating its 25'th anniversary even though the contribution of the air pump to the system is at best .... negligible.

FWIW

well the vacum under my oil cap is really strong! and the car gets dizzy just after removing the cap and the engine dies after a while, i tried to adjust the flow meter coz i thaught that more air is passing through it now but nothig helped, but i cant understand how can the engine make this vacume, coz i have the first configuration right now!

could there be a nother problem? like the thing under the throttle body, has a name like EBDD i guess ?

Well, to comment on Enrique's post, the whole California smog thing is a racket. I've been to very few shops that have any idea what is supposed to be on a 280Z. My car has never failed a smog test. I have passed with failing efi components. I have passed with a homemade cold air intake on my car. All they really want is your money.

BuDavid, I think you mean BCDD. Does your car have factory air conditioning? I noticed that on my 810, that hose under the one that goes to the valve cover connects to the FICD for the a/c system. When I pull the oil cap off of that car, there is a lot more vaccum at the opening than there is on my Z. That's probably because that connection is pulling vaccum directly from the intake manifold as it appears in config 1 and 2. Since my Z is config 3 it doesn't have that connection.

[BuDavid]

what is the FICD!?

yes i do have the A/C system, i would die withot it here;)

maybe the low vaume u have under your cp is due to the #3 config, coz the house the connects the boot between the flowmeter and the throttle body i think reduce the vacum while the throttle is blocking in idle running..

we conclude from your 810 that the strong vacum under the oil cap is a normal thing, the unstability and engine death problem under the 1000RPM is from wht then!?:s

i read in the owners manual that the hosing system the connects the valve cover and the PCV valve is used for burning unburned gases in the block, and fresh air is sucked from the valve cover through the upper hoses and run into the block to mix up with those gases to perform air drift in the block and then sucked by the intake vacum through the PCV valve to be burned again..

is it useful to cancel the valve cover hose and put a small circular air filter? i saw some engines have them, but i dont know what is the purpose of it, it might help reducing the vacum a little bit, doesnt it?

[BuDavid]

ok stephen, i found an older post about the FICD, i dont really think that my car have a similar thing, since it has an AC.. i had something like it on my 280ZX that i had b4, but mine has simply a vacum tank in series with the vcum switch.. I'll go and check under the hood, if the FICD is the valve with two vacum hoses it might be it?it is ob the upper right of the intake when u are on the drivers side of the car?

[sblake01]

I'm not sure if the 78Z had that same setup from the factory. Mine has aftermarket air conditioning so it doesn't have the FICD. What I was describing is on my 79 810 which is similar to config 1 but not exactly the same. The 810 stumbles badly when you remove the oil cap but runs fine when it's on. My Z drops rpm when you remove the cap but continues to run at that lower rpm. I wish I could be of more help here but I've never experienced the problem you're having with either of my cars.

i hope that u wont face such a problem coz it makes me go nuts :stupid:

thanx for ur concern stephen..
