Took the turbo out last night since it was dry and i noticed there was little or no boost max 3psi roughly

Got the car back home and everything looked ok. The only thing i noticed is that on the back of the turbo there is a small black pipe has halved away which is connected on by a big nut. Anybody know what this is for and where the other end should connect to?

Car was boosting fine before the battery died and it got a new timing belt, plugs and a coil.

sounds like the oil feed but if was one of these u would see a quite bad oil leak and this is on the top of the turbo also was it timed perfectly?

Jonny RS

Its not the oil feed that is a silver braided line which goes to the top of the turbo.

This other one come from the back and to the bottomof the turbo.

just tryin to think m8, u got oil feed at top, return at bottom, water feed/return assumin its a s2, charge pipe, and the 2 lil pipes that go to the amal valve which is sometimes bypassed with a bleed valve

its a lil valve that bolts to the gearbox, il will have 3 pipes comin out of it bout 8 mm diameter one goes to the snail on the compressor housing on the turbo, one to back of turbo

If you look at this pic its the black pipe at the top of the turbo that i am talking about.

the metal one? thats the water feed mate, not everyone uses water to cool the turbo as it obviously has an effect on the runnin temps

thatas the water feed, dont worry about it, aslong as everything is blocked of properly,

if your on an bleed valve. sounds like its been adjusted

Ok thanks guys,

i will get the timing checked out and see what happens.

The only thing that was wrong when the belt was changed is the when it was done previously it was put on backwards and the car had been set up on the rollers like that.
