hey i have just bought a punto jtd 1.9 85 and am concerned about the noisey whoosing under load and its dumping boost somwhere when you lift off it still goes but im a bit disapointed tbh my cinqy was mutch quicker lol are there any common problemms that affect boost or any common areas boost is known to leek. it just feels like its being held back and is whooshing and chuffing under load thanxs all(y)
 
Hi mate,

Definately sounds liek you have a boost leak. Most common place on the JTD is the flexi boost pipe that ges to the intercooler.

HAve you noticed black smoke from the exhaust under load? This is another common sign that you are leaking boost.

Have a look under the car, just to the right of the radiator, you will see a corregated rubber hose, check it for splits. Also check the hose that comes from the other side of the intercooler and goes up to the inlet manifold.

You can get somone to hold the revs up a bit to help feel any rushing air.

Hope that helps,
Alan
