Is there a diagram for this anywhere on the net? I cant find it in the FSM.. Almoste every hose on my car is disconnected :S

HAILERS

I don't think there is one for the vacuum hoses on a turbo 2. I'm fairly positive there is not. There are some diagrams of vacuum hose for cars that have been butchered up, but not for a stock car.

The best way I've found is to know what a given solenoid does in life, then blow some smoke into the vac line for that solenoid and see which of the several metal lines the smoke comes out of. Connect a vacuum hose to that opening and put the other end of the hose on the component it goes to.

HAILERS

The oil metering pump lines are given in the factory service manual. There is a picute/schematic in the LUBRICATION section that shows where each goes. If your talking about the vacuum lines that go on top of each oil injector........well they all join together in what is called a spider. The spider has five nipples. Four go to individual injectors and the fifth goes to the back of the upper intake manifold. IT attaches to the larges of four metal nipples on the back of that upper intake manifold.

There is also a fairly good schematic of the water hoses in the COOLANT section of that fsm. Which water or oil line are you interested in?

thanks, i found one okey diagram for the vakuum hoses. I cant find out where the fuel hoses should go.. There are 3 hoses, one for a charcoal filter(do i need it?) and 2 others.. one from a filter... I found the one to the charcoal filter but the two others..?...
There are 3-5 quite big hoses around the turbo/BAC area, I thought they were for coolant or some air stuff :P

I came from the garage just now i found out that my EGR solenoid is missing or something. I didnt find it and there are two loose hoses just beside the "solenoid holder"... Do i need the EGR?
I did some wiring "researche" and found at connector connected to a "thing" under the BAC.. The wires from that "thing" goes to the connector from emisson to ECU and in the exactly same "gate" as the EGR should go!

HAILERS

This is a truboII. Right? Then you don't need the EGR even if you had to pass emissions. There HAS to be a blockoff plate installed where the EGR mounted though to prevent a massive air leak.


Fuel hoses: the one from the filter goes to the most forward metal fuel line. The metal fuel line just aft of that one is for the fuel return to the gas tank. There is a metal line just above those two that goes to the charcoal canister. That is optional as far as the engine starting and running. Hook it up anyway.

Does this engine have a airpump? And a Air Control Valve? The air control valve is below the bac and several inches aft of it. The acv should have two large hose going to it. One at the top/fwd that comes from the airpump and one at the bottom of the acv that should go forward into the right fender where there is a silencer.

The ACV also has a nipple that sticks straight out at the fender. It's the one at the top. It goes to the boost/pressure sensor on the fender.

The ACV also has a small nipple at the bottom and a small nipple about halfway up the acv that sticks straight out. Both go to one of the three metal nipples that come from the back of the engine. These two make their way to the RELIEF solenoid. That's the BLUE one.

The ACV has one nipple that sticks straight up on the top. It goes to one of the three metal nipples that are just aft of the acv. It makes its way to the Switching solenoid on the other side of the engine. The GREY solenoid.

Does this car have a dizzey or a cas? Is this a European version or a USA or JDM version?

Sindregutt

Thanks, i have "plugged" those metal lines that goes to the EGR (dont know how mutch pressure it will be). The fuel hoses are connected and the charcoal canister is gone(dont know where, never had it..=)
its a European version T2 with a J-spec engine(and harness etc)
I dont got any airpump but i got the air control valve..
Where does the powerbrake gets the vakuum from?
The big aluminium IC/Turbo hose also got 2 outputs, on big and one abit smaller. What are those for?

what is dissey and cas?

kel

what is dissey and cas?[/QUOTE]


Distributor or Crank Angle Sensor (CAS)

- k -

Sindregutt

it got a CAS

But are you sure the fuel hose from the filter is to the longest metal line? it goes from the filter, to the fuel pressure valve and then to the injectors?
I found a diagram and it didnt look like it on that diagram

Sindregutt

The ACV got 3 big hoses or maybe 4! the biggest is a metal line, then the one pointing to the right fender, one smaller pointing straigth upp and the last one pointing forwardright

HAILERS

The fuel lines on a JSPEC are opposite the USA , so my picute was wrong for you.

The brake booster line comes off the rear of the upper intake manifold.

Here are some pictures of USA vacuum hoses. Most are split into more than one jpg.

The big aluminium IC/Turbo hose also got 2 outputs, on big and one abit smaller. What are those for?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^

The large hole is for the blowoff valve or Air Bypass valve as MAZDA calls it.

The smaller is for a checkvalve which in turn is connected to a vac looking line that crosses back over to the other side of the engine. It is a purge line for fumes in the internals of the engine.

The JDM ACV is different than the USA. But they function the same. There should be but two large hose. One coming in and one going out. The JDM one that goes out is located to the aft side I THIK but still goes to the right fender. You can leave it off and forget about it since you have no airpump. Same with the one coming in at the top front. Forget about them.

Only one hose on the ACV has value to you. It should be near the top of the acv and pointing straight out towards the fender. It supplies vacuum to the boost/pressure sensor on the right fender.

Like I said earlier, the fuel lines are just opposite on a JDM, so the jpg below is not of much use to you. Maybe others.

HAILERS

.USA air control valve jpg attached. Now you see why we can't communicate about acv.

HAILERS

The brake booster line is in the jpg attached. It is the large nipple where all the red lines converge. Not any of the four nipples, but where the four redlines converge to the left. If I remember right this jpg is upside down.

Sindregutt

hmm. Yeah now i understand why we cant talk about the ACV.. But i can remove it? right?...

HAILERS

&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& &&&&&&&&&&&&&&&&&&&&

By the authority vested in me, I now give you permission to remove the ACV. humor

Make a plate to block off the hole your leaving. Also consider something. There must have been a single small, metal vacuum line sticking straight out from the acv near the top of it. You NEED to either put a nipple on your blockoff plate to replace that source of vacuum for the boost/pressure sensor, or tee off from another place on the manifold.

Sindregutt

okey :P: Thanks ....... :P:

I`ll make a blockoff plate with a nipple for the pressure sensor.
The other hoses that goes to the ACV has to get plugged?(stopped or whatever)

HAILERS

On a TurboII ACV there is only one small vacuum hose that has vacuum on it. It's the one that connects to the nipple on top of the acv that sticks straight up. The other nipples on the ACV do not have a vacuum going or coming from them.

That one small vacuum hose comes from the other side of the engine from a solenoid that has a GREY electrical plug on it.

Personally, I'd just make or buy a few small vacuum caps and put them on any open metal nipples that are not being used. That keeps dirt etc from getting in them in case you want to use them again someday. You can make your own caps by cutting a piece of vacuum hose and plugging one end with RTV...letting it dry and then installing the non blocked end on the metal nipple/pipe.

Sindregutt

hmm thanks.. Ì`ll take some pics tomorrow of some hoses i still dont understand what are for!

Sindregutt

Okey, i was out taking some pictures... i got 6 hoses i still dont understand what to do with.. Please write the number on the hose and tell me what to do.. As mentioned before i have removed the ACV and i aint got any air bypass valve..

Thanks.

Sindregutt

hmm, someone know where to find the dim etc on the drive belts?
Didnt find it in the FSM or parts catalog

Sindregutt

Hmm, i cant find any O2 sensor.. its deffinitly not on my exhaust.. Must i have it to start the engine?

Sindregutt

okey now i have capped #6 and plugged #4 and #5 together...
I`ve also plugged #2 to #3 .. But what about #1?? i cant find where to plugg it..
Not to the IC .. And my BOV is gone.... Just cap it?

gassrx

#1 does go to the intercooler.
#2 Also goes to the intercooler.
#4 goes to the switching actuator under the turbo.
#6 I believe goes to the fuel rail above it.

Sindregutt

i`m 100% sure that my ic aint got more than one input and one output
