hi i'm trying to find the cause of my uno turbo mk1 smoking. the engine had 81,000 and has been refreshed with new piston rings and new polished and ported head. not sure on the condition of the turbo though, i seem to let out loads of blue smoke on deceleration after its been drove hard. last time i checked the plugs they were nice and brown, will check again tomorrow. This is my second engine as a piston ring went in my last 1 and that smoked all the time. luckily found this mk1 turbo engine which had so much less wear in the bores i decided to get new rings anyhow. can any1 help thanks
