Hello all,I am new on here and a bit desperate for info. I haven't spotted any 'broken cam belt' threads so far, so I will post over in the right area about my wife's 2005 CMAX 1.6 TDCI with less than 25k on the clock which had a broken cam belt last week. It appears these engines aren't designed to cope with a cam belt break. [img]smileys/smiley7.gif[/img] (My old '89 Escort back in the UScould handle that without too much bother.)Sounds like CMAX's enginemay be knackered.[img]smileys/smiley19.gif[/img] Waiting to hear back from the mechanics after they get the engine apart to inspect the damage. Not very happy with Ford after my Alternator on my Focus shorted to ground about 6 months ago nearly catching fire not to mention toasting some of the electronics.Will post in the right place now.cheers,William

Hi William,

Sorry to hear about your cam-belt woes. Truth is, nearly all modern
engines, particularly Diesels due to the higher compression ratio, will
cause quite a bit of damage to the valves and their drive mechanism when
the still moving pistons contact the now stationary valves. It is
because, in order to extract more power from an engine of a certain
size, the valves are bigger and open farther than used to be the case.
This means that, when they are open, they occupy the space where the
piston is when it's at the top of the cylinder at the end of the
compression and exhaust stroke. The valve timing mechanism (Camshaft
etc) ensures that no contact occurs during normal engine operation, but
when the cam belt fails, the result is inevitable! Your '89 US Spec
Escort very likely had a fairly low compression engine with not a lot of
power for its size in comparison to European counterparts. I seem to
recall that was done to enable the engines to run on the lowest quality
unleaded fuel which was available there at that time, don't know if it
still is.

It is very unusual for a cambelt to fail at such a low milage. They are
usually good for upwards of 100K these days. If the engine is U/S there
are plenty of 2nd hand ones available from breakers. It is actually a
Peugeot/Citroen Unit that they call the HDi so that should widen the
search if you need one.



Hope you found this useful.

Regards. Colin

Thanks B.B.You are right. The fuel in the States is rubbish; both petrol and diesel. I think the reason that they don't have any performance diesel engines there is because their dieselis so poor; industrial grade for lorries.What do you mean by if the engine is 'U/S'? Sorry to be thick. Somebody mentioned that getting a used engine may cost a fair amount in reprogramming the car's computer to 'accept' the new engine. I'm sadly lacking space to do much mechanical work myself and cars these days are much more complicated than my old US spec '89 Escort GT when I lived there. (I have now ordered the Haynes manual for the CMAX [img]smileys/smiley17.gif[/img]. There will no doubt be some use for my focus estate as well.)
