Gti6 Engine, Where Is The Servo Take Off?

[Fox 3]

As title really, I've been sorting the last bits on my gti6 conversion, but have come slightly stuck on the brakes.

 

There seems to be two vac take offs, one on the manifold, and one on the rocker cover at the end of the head.

 

I've seen photos that show a pipe connecting both of these, and then to the servo, but I'm missing this pipe.

 

For now, I've stuck the vac pipe on the inlet manifold only and the brakes seem to be ok (i've not driven it properly though!), whats the pump for?

i sent you pics didn't i matey?

 

of the cam it goes to a valve (one way i think)

 

then that "T"'s to the brake servo and the other connection goes to the first pic

as spiky said you're missign one of the pipes and the valve

[Spiky 37]

hope they help matey

Hmm, it does appear I'm missing those, bugger.

 

So i'll need no's 12 & 10.

 

What are 8 & 9 for then, where do they go? Hang on, theres two no 8's!

why not just get on the gti6 forum and buy off there, there probably loads laying around

[M@tt 77]

that short no.8 isn't present on mine it has a little blanking cap on it

[welshpug 1,657]

the diagram for the P1 306 doesn't quite make sense to me, the P2 on does though

 

 

No 14; 457293 BRAKE VAC HOSE £13.29

 

No 8; 457221 BRAKE VAC HOSE £18.72

 

No 9; 457243 BRAKE VAC HOSE £6.28

 

No 10; 457519 AMPLIFIER VALVE £19.54

 

No 13; 162460 PLUG £1.15

 

there's the part numbers you'll need going of what I can see in the pics of your engine and what's listed for the Phase 2 on gti6. £58 +vat!

 

pieces 8 and 9 however are just the overbraided large bore vacuum hose so you can substitute these for ones sourced elsewhere.

[Spiky 37]

didnt think it made sense..lol

 

 

that one does though

[Fox 3]

Thats better! Does pipe #13 go to the cam one then? Is 9 blocked off?

 

I might get away just getting no 10

[M@tt 77]

if you get stuck i'm sure i've got some spare vacuum hose i can send you, i won't be able to send it till friday though as i'm away till then. Drop me a pm if you haven't soreted anythign before then.

[Spiky 37]

9 to cam

13 is blanked (on mine)

8 to inlet

and 8 to brake servo

[welshpug 1,657]

no 9 goes to the vacuum pump, left hand no8 goes to No14 which is connected to the inlet, No13 is a 15mm long blanking piece.

 

second No8 on the right goes to the metal pipe on the bulkhead, you could dispense with that and connect your servo hose there.

[M@tt 77]

i think you'll need

10, 13, 14

and the rest can be done with some vacuum hose

[Fox 3]

Sweet, cheers for clearing that up chaps, its hard when your missing bits to work out whats ment to go where!

[Matt Holley 11]

Is there any real reason for the vacum hose coming off the inlet manifold? whats it for, I am using carbs on mine so just use a hose from the pump to the servo, does the pump use vacum from the inlet to add extra vacum for the servo?

[Spiky 37]

is it used to advance the cam?

[Matt Holley 11]

is it used to advance the cam?

 

No the cams just drives the pump.

[Spiky 37]

ok, didnt know what it was for...lol

I have a question about the vacuum pump on a S16 lump as well. I'm planning on running without servo-assistance on the brakes (with a pedal box, hi Spiky ). Does this mean I can ditch the vacuum pump. How do I block of the feed of oil from the cam, just jam it up with a bearing and cover the hole in the waterhousing with a plate?

I use just the pump, All Derv's do as well

on mine i just blanked off the outlet that was going to the servo, and the pump is still plumbed into the inlet manifold

 

and also i not forgotten about you my track day at donny was cancelled

 

but going to oulton park on the 17th of jan, and will test the pedal box then

[Fox 3]

Good news! Look what i found hung up neatly in the garage last night! I don't remember it being on the engine, and its not on the engine in the photos I took when I got it, So I assume it must have been loose with the other bits.

 

 

Unless someone snuck in and put one there...

 

Saved my self some money anyway!

 

I'm such a tit
