190d smoke
 

84 190d 2.2 Just bought this car It has almost no blow-by and has had its oil changed every 3k miles. On start -up there is very little smoke, but when you rev it up or apply more power the smoke just billows! The seller said it started to smoke all of a sudden.I have heard of these cars going 500k and this one only has 180k. Any help would be greatly appreciated.
