R32 Gtr blowing smoke

[GimpyDammit]

Hi All, 

Recently (dec last year) had the rb build at Mick's motorsport. New turbos fitted too.

Drove the Car around a bit and was all ok. Did 2+ hrs each way up the coast and back and all good.

Went to visit wifey at work, got 20mins down homebush bay drive and the car started blowing huge plumes of white smoke. Managed to get the car to her work and leave it there until 9 at night. Got the car at 9 and it drove home with no issues at all. Took it out the weekend after and got 20 mins down pennant hills road and it starts blowing smoke again.

Car has been at CRD for a 4wd fault and no issues when they road tested it.

Blew an intercooler hose off today driving it, hose was clean, no signs of oil. Got the car home and into the garage and after 5mins idling, started blowing smoke.

Any ideas on where to start?

CO2 test the coolant.
