    A few problems with z20let

    Hi, the first main problem is that the car has been smoking from the exhuast for a while now, but still drives fine and i was wondering what it is?

    And also everytime i turn my AC on a warning light comes on my dash and the car starts to idle rough.

    If anyone can help me with either of these i would be very grateful, thanks Dean

    AC fan might be dead or dying, turn on AC and see if the fan starts up after a few minutes.

    As for the smoke, need to know colour of the smoke really to give you a rough idea what it might be.

    blue smoke = burning oil
    black smoke = overfuelling = not burning all the fuel
    white smoke = using water

    hi, thanks for the reply, the fan turns on as soon as i turn on the air conditioning, and also its white smoke, it dosent start straight away, but once the engine has warmed up it starts, and if i take it on a drive it stops for a short period but will start again once its been left idling for abit, any ideas? thanks

    smokes usually a bit bluey/grey if the turbo's had it,although sounds like your turbo is on it last days if its whining alot....my guess would be head gasket too.

    Turbos is dead mate, bearing is gone and if you keep driving it you'll be doing more damage, probably take the shaft out too.

    Get you precat off and have a feel but if it does whine then im 100% its dead.
    With the mods in your sig i take it your boosting high so thats whats killed the bearing as there crap.
    Anymore than standard and they soon say BYE BYE
