2004 Ford Mondeo LX 2.0 from UK and Ireland
Ford now engineer their cars to rapidly become scrap
The engine. Ford designed this engine to fail early. This is a complex and potentially heated discussion, however the facts are this. Manufacturers, in order to get higher MPG have made internal friction less by reducing the piston and oil control ring thickness from 1.5-2mm to only 0.6mm. This can cause (or often causes) premature ring wear and failure. In this car the compression rings were fine. From many years of experience I also believe this car was not clocked and the mileage was genuine. However the oil control rings had worn out. I know what you are thinking - they were not worn but 'stuck'? Yep I thought this too - however after a great deal of effort, they were not stuck, but most definitely WORN OUT. Thus the engine smoked lots and was an MOT failure.
Firstly this means Ford have deliberately designed the oil control rings out of a different alloy to the compression rings with the sole aim of early failure. There can be no other explanation.
I also hear you saying: No problem just replace the oil control rings... you do know what Ford deliberately and intentionally made this a 'disposable engine' - their own company words. This means that the cam belt pulleys are not keyed but held in place just by tension (a whole shed load). Together with numerous other aspects, this makes taking the engine apart in any way - a real mission. Some very determined people have done it, but for the majority of us, this means the engine... oh I mean the car literally goes to the scrap!
Ford intentionally are making junk. Ford today are not the Ford of yesterday. Do they really hate their customers that much to do this?
Would you buy another car from this manufacturer? No

Petrol or diesel? You don't specify. Anyway, the diesel engine in this car was a dog - as are most diesels from early 2000s onwards.
Your car may not have been clocked, but you may have had an poorly serviced bad example.
Not a Ford fan, however I must say I had many mk1 and mk2 Mondeos in the 1990s and they were great - the mk3 2001 model onwards however I've heard mixed reviews, with complaints similar to yours. The newer mk4 2007 onwards Mondeo is a huge improvement though, but I'd still be wary of the diesels.

Don't know about the petrol engine in these cars, but I had a 2005 Mazda 6 2.0 diesel and it was awful. Problems with dual mass flywheel, diesel particle filter, injectors, etc. You name it. Looked after the car as well, and all when it was only 4 years old with low mileage (35,000). A very expensive mistake I will never make again; modern diesels are awful when they get a little older.
I'm fairly certain the Mazda and Ford share the same engine from the same time period, or at least it was designed in a similar way. Shame really as they are otherwise pretty decent cars; I'd maybe take a chance with a petrol one again, but not diesel.
