Loss of boost

Recommended Posts

Guys,

 

On the way home I noticed that all of a sudden I was only hitting about 0.8bar, I know that this morning It was around 1.1bar! I naturally checked the boost controller and it hadn't been changed! I am also hearing a loud 'whooosh' type noise as I ease off the throttle at high revs!

NOTE: Its a different noise than that of my bov! and its only appeared today!

 

I have checked pipes etc and all seems to be ok, when I blip the throttle cable I notice that the intake pipe which goes off into the drivers side wing 'clenches' not sure if this is normal!

 

Please help, as I am a little worried about my baby!

You need to pressurise the intake system. The americans do it by using a baked bean can in the end of that pipe going into the wing with a tyre valve in the middle. Attach the valve to a compressor and then pressurise the piping and look\listen for any leaks.

washing up liquid, should bubble and froth on a leak, tends to make stuff sticky tho. asda own brand would be fine, i cant tell the difference between that and the hks washing up liquid.
