nissan serena engine probsm please help!!!
 

hi,
have a m reg jap import serena 2.0td
was working fine till other day, then all of a sudden, got blue/purple smoke, chugging, lack of power and half economy!! please help as family car!! not sure if it was the fuel i put in or what but hoping it can be repaired

when's the last time you looked under your seat??? how could your engine possibly fit between your tail and the road, unless it was one of those new half-cylinder pancake jobs.
