wel usal escort problems, the motor used to smoke and it was down to a shagged turbo, got a brand new freshly rebuilt stg2 t3 and fitted it,all ran good ect, then its started smoking again, i took my ic off and cleaned it out(full off old oil) then started it up and was sweet as fuck, but now when i let it idle then go it smokes and if im in say 2 going down a hill and the cars slowing down with the revs it smokes badly, valve stem oil seals ?????????
