was on the way to work this morning and having a good drive through the countryside - came to overtake a bin lorry and the engine started juddering and i lost lots of power. the first thing i thought was damp filter but ive had this problem loads before and that is different in that it just cuts out once for half a second or so.

 

what i noticed on driving was that being gentle on the throttle was ok, but when i started to build up boost, it started juddering again, and i could hear air escaping from what sounded like the driver's side near the front bumper.

 

also it would try to stall on me when out of gear, but as long as i blipped the throttle then it would pick up again.

 

i checked what i could at work - nothing untoward in the engine bay (apart from the severed wires at the dett sensor connection that i posted up about in another thread but thats been like it for weeks), i checked whatever piping/connections at both intercoolers i could reach, hardpipe connections seem ok, no great big hole in the intercoolers (that i could tell anyway), dump valves seemed ok...

 

on the way home this evening i took it steady and she ran fine under gentle driving - even idled properly - but as i got close to home i tried building up boost again and the problem was there - sounds just as if a major boost pipe has come off on the driver's side. not just a psst or hiss, but a whoosh. could any piping have come off nearer the turbo?

Dont know get out there and have another look :rofl:

 

Hope this helps

Near front bumper could be a pipe has popped off the o/s intercooler or one of the connecting pipes. Worth a look, but front bumper will need to come off if that's where the leak is :(

i had an air leak on an inter cooler

the plastic part is sort of crimped on by loads of little metal tabs

somehow they moved out a bit and started leaking

so took off cooler hit tabs with coal chiseal and hammer and closed it up

they have been fine since

hope you get it sorted [bloody cars]

 

if you made an air leak tool should be easy to find your leaks

theirs a thread somewhere to make1

 

good luck

Hi Guys, Is there any way a doing a boost pressure test?? and if so how??

Boost leak detector, you can pick them up from somewere, there is also a link on here how to make one.

You will need a compressor to provide the quantity of air required to find the leak.

Good luck

thanks Jeff - I'll see how i feel tomorrow and i might pop in. :)

just got back from Jeff's - they told me the piping had almost come off both sides of the driver's side turbo!!!! my GOD i had the drive of my life on the way back!!! after my other thread about not being able to beat 14psi no matter what settings i dialled in - after dropping the settings for safety reasons before i left, i hit 16.6 straight away and the responsiveness was immense :shock: just needs a little tweaking to get it to 17 and a bit out of it now ;)

EXCELLENT NEWS!!!!!! Nice one Dave. Bet it scared ya a bit did'nt it :D
