Ford Mondeo LX TD Turbo Diesel Estate - HELP !!!

[hanc1706]

My Mondeo has developed a problem that no-one can seem to solve... The car starts ok, but now and again, the engine begins to slow down after a few seconds, starts to make a knocking sound and then races. The REV Counter hits maximum and I create an enormous smokescreen (white smoke) for about 4 or 5 seconds. When the revs subside, the car runs ok apart from blowing smoke for 1 or 2 miles. The only suggestion that seems to make any sense is that oil is getting into the fuel system causing the engine to race until it burns off. However, the mechanic had no idea how it could be happening.

Any suggestions ?????

Rather dependson how old the car is. if it's a tdci (the present shape} then go to the mondeo enthuiasts group site. they have an excellent technical section. if not, try it anyway. the distinction is that the later model suffers from early failure of the egr valve causing major problems similar to the symptoms you describe. other than that, the oil in fuel scenario is not plausible unless 1, the oil level is too high 2, worn engine, high crankcase pressure/ blocked breather or 3, turbo failure. good luck and keep us posted !
