Title: What should be here?
Post by: gusco on 01 August 2008, 14:24

I've got a 1992 sportline. I've only had it bout 3 weeks.

I was under bonnet yesterday and I found this bolt in a pipe.

What and where should the pipe attach to after I remove the bolt?

Cheers for any help

hi mate just looked in the haynes manual and on their diagrams and pics there is no pipe coming out of that rubber boot to the throttle housing

however my haynes only covers up 1985 gti cabbys

so ithink it should be blocked off or i wondering if it goes to the

HOLD ON!

just looked in the supplement and it  goes to the idling speed boost valve via various junctions and additional hoses

i think the boost valve increases idling when lights, heater, etc are on

im thinking that the boost valve was maybe superceded in the late model cabbys and therefore the pipe blocked off

sorry cant compare with mine as i have a 2l 16v  :evil:  :grin:  :grin:  :grin:

here you go, I've got a 92 Cab which is the same spec engine as yours - its should be blocked off, but not in that way.

Mine has a plastic stop where the green connector is on your with the additional piping!

Pic to help you see...

that hole is probably there as the boot is a later part that superceeded the early k-jet one, designed for digifant cabbies where it would be used for the ISV or breather system.  if the later one is then fitted to a k-jet car the hole is not required and is blocked off.  either that or its desiged for MK1s with a lambda!
