hello: looking for some info.I have a big turbo escos and the car has become very sluggish over the last week , it does not seem to build up boost and there seems to be what sounds like an air leak when the boost comes on .What is the best way to find out where the leak is coming from?

 

youve checked the obvious like all the jubilee clips holding the hoses on tight?

 

Try squeezing all boost hoses and seeing if there are cracks etc...... replacing any that look like they are tiered.

all jubalie clips too, have a look around the engine and see if anything is hanging....
