Angry Snapped timing belt on Tdi

I think I broke my timing belt while running yesterday, engine just shut down, won't start again, no diesel going to injectors.
I'll get a check to see if valves are moving thru oil filler this morning, just to be sure, but I have that feeling that it snapped.
What other troubles I'm looking for ?

Cheers

Hi julien, if it is the timing belt your looking at replacing some bent valves for sure, check them all carefully, its also common to snap or crack a rocker.

I've seen valves bent so bad they jammed in the guide, that timming belt let go at 3k rpm with a bang.!

let us know what you find, i hope it's not the injection pump thats died.

regards
Gren

When my belt snapped it bent a handful of pushrods. That was the only significant damage. Your pump wont get fuel because it is not turning. I hope you don't have more damage. Good luck

Td5's have timing chain not belt. Do not need to change like the 200/300 belts.

Great write up, I have the 300 but the timing set up is quite the same I think.

Yup, one of the last factory fitted Tdi, there is a fella in the Caribbean also, I think it's in St. Barth with an 06 Tdi.

Never changed. 75,000 kilometers.
I'd guess time broke it, 7 years of
daily use.

Also check the brass bits (I think they are called tappet guides but can't remember) below the push rods. I had one break. Nice to hear there was only minor damage. Oh, since the water pump is off, replace with new! Cheers
