Hi,   First post here and Im looking for a little advice please,   I have a 2004 2.8 grand voyager crd until last week it was working fine, then during a long journey it started smoking from the exhaust white with a tiny bit of blue in it.   the smoke is worse when idling, not noticeable when crushing although worse when accelerating hard. the turbo is making a kind of noise similar to a drill/whistle.   Any suggestions welcome   Thanks in advance
