whats happened

[stedee]

right i was cruising about 3000 revs slowly accelerating, i had just cleaned my lambda sensor - hoping it would sort out my lean issues - then i heard a pop (not loud) and a swish noise which it is still doing, obviously its something to do with the turbo, i`m hoping its a pipe popped off, it still boosts to just under 0 but i am scared to put my foot down any further, no smoke or nasty noises just a louder turbo noise.

 

[cole]

do u want me to come and check it out ?

 

[Dub-Se7en]

sounds like you've popped a boost pipe.

 

[Rory]

You have either poped a pipe off, or split one.
I keep doing this at the minute!

 

[stedee]

do u want me to come and check it out ?

a big fcuking yeah - i start work at 9 but if you can come nowish - much apperciated.

 

[cole]

let me jump in shower il be half n hour pm me your phone number m8

 

[Sheldon]

with what you cleand your lambda? i did read somewhere if you try to cleant it with some spirit/wd40 you will get a useles lambda..

and for the big pop sounds like you poped a pipe off like mentiond

 

[dantheman]

mate if you say it still boosts to just ender 0 on the gauge then it is not boosting at all sounds like a boost leak/pipe come off or split.

 

[cole]

hes found the problem boost pipe popped off

 

[dantheman]

well done easy fix then

 

[stedee]

yeah popped the intercooler pipe off - jeeez give me a heart attack - i thought it was but in the back of my head - the ol imagination run wild.

you know what i mean - i dont actually know what changes the negative pressure to atmospheric whether its just air being allowed through with the turbo spinning - i dont really know!!!!!!!!!!!

 

[dantheman]

lol anything after 0 is positive pressure ie boost, under 0 is vacum

 

[stedee]

yeah i know that but the turbo needs to spin to change from neg to atmos or does it - i know the air is being sucked in before o by the action of the pistons an then after 0 the turbo is pushing the air in.

 

[dantheman]

when the gauge goes over 0 it is boosting. if it dont go over 0 then it isnt

 

[stedee]

ok ok i consider myself told, boo hoo

 

[sx_turbo]

mate your "lean" issues are probably down to poor tune.

when a lambda breaks its normally causes over fuelling.

what makes you think your running lean?

 

[cole]

he put new plugs in and aparently they went white instead of golden brown

 

[dantheman]

how long did he run on new plugs before checking though as they dont always go brown straight away
