there is oil in the piping, so i know that the turbo is shit. but why would it happen at idle. it does blow smoke when you back off the throttle, but i didnt know if that was associated with the idle smoke.
the headgasket went cos someone forgot to switch the thermo on lol, ive wired that up with a relay now so no more worries.
its a t28.
ill have a look at the oil drain.
funny thing is. i started it then and there was no idle smoke, only off throttle.
