Consequence of a timing belt snapping

Hi good people.
I am sitting here contemplating the consequences of a snapped timing belt. Not that it has snapped, by all means. But is it a death sentence for all engines? Even the good old 1,9D in the MK1?

Re: Consequence of a timing belt snapping

Death sentence.

Had exactly this on my 1.9TD Synergie at not much above idle revs. Very similar engine. It was full disaster - piston hit the valve, sapped the cam shaft, broke the threads hoding the rocker cover.

When the mechanic says "I didn't change the belt like you asked because it looked okay", insist on changing the belt  mad

Thanks, kenbw2. smile
Wow yikes That is far beyond repairs...Belt-kit and glowplugs are in the mail, as we speak. Wouldn't want to lose this car due to lack of maintenence. Put down quite a few hours in it already to get it through MOT, and has plans for a removable camper conversion.
Do you happen to know the interval of timing belt replacing?

I believe approx 5 to 6 years or 50,000 ish miles - whichever comes first. Just changed mine after 6 years and 12,000 miles. Old one had only done low miles, but rubber degrades over time. Always buy quality Gates or Dayco belts.

As the saying goes - belts are cheap, engines are expensive.

Had a couple of lucky escapes over the years. The belt snapped on my 1.6 Montego but luckily these weren't interference engines so no components collided and no damage done. Couple of years later, going down to Devon in brother's 1.8 Sierra and engine started making strange noises and running rough. Turned out the belt's tensioner or idler (can't remember which) had started failing and the belt jumped a couple of teeth. Luckily no damage to engine this time either.

Re: Consequence of a timing belt snapping

not always the end of the engine...  i managed to replace the cam shaft and journal bearing caps and the engine was fine after. best thing with the older XUD type engine is that the valves point strait down not at an angle..  so the valves very rarely bend. the force just gets pushed up to the cam shaft. and being as that is only cast it just snaps.

though i no longer have the car now, it is still on the road which leads me to believe that its still a good running engine. the car its self would only be worth scrapping if the engine ever went again as it was rather rough.

Re: Consequence of a timing belt snapping

How about the piston top? No damage when hitting the valve so hard it snaps the camshaft? Well, the belt will be replaced..
