Hi, at the min our nova is ready for the final steps of the conversion, the fuel tank/suspension/welding/brakes/shafts etc are sorted, and were just putting the last parts of the engine together so we can get the engine in situ.... There are a few bits however that we are stuck with. We have tried working to the c20xe cavi haynes manual, but cant trace a few of the parts locations, and hope someone on here can help. Ive hosted some pics up....
Does the bottom pipe go to the EGR and then from the EGR to the SFI box? And what attatches to the threadded hole on the inlet manifold?

Any idea what these 3 pipes are for, and where they go lol?

And do we need the multi pipe thing? Also theres a sensor thing with a vacuum connection on, where does this go and whats it connect to lol.

Were happy with all the water pipes, its just the odd bits that are left, seeing as our engine came in boxes lol.

ah im a:tard: 1 is the water pipe that you will need to t piece into the expansion tank pipe that goes to the top of the rad
2 goes on to the vacume pipe that goes on to your master cylinder iirc
3 gose on to your rocker cover next to the big one

in the first pic where you wrote egr thats where you idle control valve should be

Cheers, so where does the multi pipe thing go? And the vacumm sensor thig that fits in the loom, where do i get the vacuum from? Is it off the inlet or the vacumm from the fuel rail:S
Also any ideas what the hole on the inlet is for?

is the hole in the inlet not for the 3 pipe thing

06-04-09, 07:46 PM
doesnt seem to fit, bit too loose lol

06-04-09, 07:48 PM
the 3 pipes deffo go on to the inlet

il go and have another quick look and see. The 3 piece thing looks like its had water in it, is this correct?
16v Nova Kev
06-04-09, 08:07 PM
edit it is water lol

ive just had a look and i cant get the 3 piece thing to screw into the inlet, as it wont screw in (restricted by the manifold itself).

pm me your mobile number and i will send you pics of the pipes on mine

For the vacuum there are two pipes on the bit that bolts onto the top of the manifold. (the TB)

are you talking about the thing with the two water pipes running off it? if so watch out cos i snapped the bolt trying to tighten it lol had to take off the inlet to sort it out.
if i was a mechanic and knew what everything was called i could of told you exactly whats what as iv had my inlet off so many times within the past week or two Lol.

Lol... im not sure if its even supposed to go in there, but i was told on here it should, but when you spin it the taps that come off the 4-way thing get in the way, making it inpossible to turn round to lock into the thread. We are probably missing parts.... I was reading that the hole on the inlet could be for the brake servo... confusing lol :S
1, is the water one thats ment to heat the bottom of the tb. But youve as been cut so asless you can get the right 2way bit of hose you'll have to just join it to the water system (normaly the run off from the rad)
2, is the fuel pressure, which off hand i cant remember when it gos.
3, is the hight pressure oil breather from the cam cover.

aah after a search it looks like im missing a connection of some sort.... (bottom left in the pic)... any idea what it is for? Although this connection looks to come off the side of the inlet, where as mine is on the centre... :S

If anyone has any engine pics i can zoom in on i would appreciate them, other than that i might see if vauxhall will be nice and print me some sheets off....
Thats the take off for the servo.

Thats the take off for the servo.
Ah, so i need some kind of threaded connector to fit in, and then run that off to the main pipe on the brake servo?
It wouldnt be so bad if the engine didnt come in parts... and the haynes manuals are worthless lol... its annoying as we are nearly there with it, but needing little bits is slowing us down.
Nearly there? Dude your miles away..lol
Is the threaded bit missing? If it is then yes you need a bit that screws in then you can jubliee a pipe on to it. Needs to have a non return valve in it.

Mine....

Iirc thats where the pipe from the fuel reg connects too.

haha not miles away (shuuushhh)....
Just looked at my inlet manifold and i have the vacuum thing for the servo out to one side, with a non return in place by the looks of it. Then i have the idle control valve attatched, and im just left with a threaded hole near the top of the manifold :S.....
Just need to know what the hole is for, and what exactly fits in it...

Ah, the small vacuum type connection to that copper one above the hole im having troubles with? (the one next to the connection with the pipe on)...
Where is the hole? The one in the middle just under where the tb mates? Thats the breather, whih has the water jacket around it..
The brake take off is right, the icv looks right,

yea the one in the middle under where the tb mates.... so does it have anything connected to it, or is it just left open as i would have thought something would connect up to it.
lol you cant just it open. you should have a bit that looks like this..

You can see where the water pipes should connect.

just looked at mine, and the 3 piece thing i have seperatly looks as if its supposed to go in the manifold as the pic you have upoloaded for me... yet the piece cant be turned into the thread as the inlet gets in the way :S

i must need a smaller connector :S trip to vauxhall tomorrow morning then im guessing, as i need another connector for the fuel rail, and a gasket for the gearbox...
Also need a crank sensor as mine isn't on the loom. Can any vauxhall crank sensor do as i have a sensor of one that looks as if it will fit, and its also three pin... or will this throw up a fault? Do i need to stick to an astra 2.0 16v sensor?
I comes apart. The bit with the water ways comes off the screw in fixing.
But it comes off from the inlet side, if you undo it and it will be hard, that will break the dirty seal thats holdingit together. Why do you want to remove it?
Bar that it will be blocked with dirty oil.
ST-eater
06-04-09, 09:40 PM
i dont want to remove it, wanted to fit it.. it was in one of the boxes when we bought the engine lol.
Soke it in a degreaser, and work at it and it will seporate. Then you can clean it and put it back together..

Its now in place in the inlet :D cheers!! Rep Given!! haha...
Can you tell me where the two water pipes off that part tap into and where the breather hole links to....
Any idea on the sensor?

one of the pipes has to go into a T piece off the header tank and the other goes on the pipe sticking out below the two on the rocker cover on the left handside. if i have time 2moro il take pics of the whole inlet for you to show you exactly what goes where, will be easier to explain

Ive decided to do a little doodle to see if anyone can confirm wether or not my pipes are correctly fitted. Easier to explain with a doodle lol, although its not the greatest drawing!! Can anyone tell me if its correct, and if not how to correct it. also where do the two pipes lead to with the '?'
http://img152.imageshack.us/img152/7990/img102l.th.jpg (http://img152.imageshack.us/img152/7990/img102l.jpg)
The sersor on mine is blocked off. Can even think that it is.

does my scetch look about right?
ST-eater
07-04-09, 09:09 PM
Yes.
Whoop :D Cheers.. so are both of the pipes on my scetch with '?' on blanked off? And finally where does the fuel rail reg get its vacuum from?
Christ, i'll pull my engine out tomoz and take a pic.
But looking at my pics, it looks like the fuel reg one does connect to the fuel tank vent valve, with the other pipe blocked off.
right here goes.
rad connects as usual lol
outlet on the right hand side of the head (under dizzy) goes to the right hand heater matrix pipe
left hand heater matrix pipe goes to the left hand pipe on the plastic water rail (rear of engine)
right hand pipe on plastic water rail (rear of engine) goes to the header tank.
remove both water pipes from the 3way piece on the inlet (dont need blanking) Run one length of pipe going from the nipple on the left hand side of the inlet manifold straight to the header tank (T piece to join to the small pipe on header tank)
that should be all the water pipes sorted.
vacuum pipes like this.
small breather on rocker cover goes to the 3 way piece below TB
large breather goes to TB
Lower inlet (big pipe) goes to Idle Speed control valve using aprox 1inch of hose, the ISCV then goes to the SFI box.
FPR goes to the smaller left hand vacuum nipple on the front of the TB (below large breather port)
The Fuel Tank Vent Valve will normally connect to the Larger Nipple on the TB below the Large breather port.
think i have covered everything, anything else dont hesitate to pm me
