Broken timing Belt.

Sorry meant clearance not compression, I see OCUK motors is still on top form of criticising someone elses advice rather than contributing themselves ;)

The whole point is that due to the very high compression the piston/valve clearance is very small anyway. You'd have to be extremely lucky to get away with a broken timing belt on most diesels.

Is bad advice worse or better than criticism then?
 
not always, I had one go years ago and did no damage at all

Very very unlikely nowadays, in fact the tolerances are getting so tight cambelt failures are now breaking camshafts and valve guides.

Often cheaper to buy a recon head rather then repair the damage.
 
My partners timing belt snapped on her Golf MKIV GTI.
We stripped the head down, the pistons were completly shot to pieces, all the valves had hit the pistons making them virtually useless.
Managed to replace most parts, and get it going, just!! and sold it back to VW.
In all fairness we should have changed the engine, but 7 years ago engines for these were still quite dear.
 
Vauxhall ecotecs are the ones you have to watch out for, the belt snaps and wipes out the valves only leaving scratch marks on the piston crown, nothing too special.

You replace the valves and a month later the car comes back with oil pouring out the back. The impact causes the piston crown to just pinch the piston rings and after a couple of weeks they groove the liners.
 
It's clear what the advantages of chain driving rather than belt driving an engine are, but are there actually any advantages to belt driving an engine?
 
- Belts usually run quieter than a chain
- Cheaper for the manufacture to produce an engine with a belt
- They can bill you for changing it
 
Sounds like you left it a tad longer than advisable ;)

Water pump and belt, may as well have them both done at the same time (advice from a specialist), would be anything upto £700 inc labour at some of the local vw/audi specialists round my way.

Hopefully you'll get lucky and it won't have wrecked itself and as mentioned above these cars still hold reasonable (no idea why when they're so expensive to fix) value so if it's the worst then consider a replacement lump.

you mean correcting your incorrect advice ?

Check it first or dont contribute at all. Whats the point in contributing incorrect information ?

Yes I believe it is advisable to do the water pump at the same time, plus the the belt kit will also have the tensioners, remindes me I need to confirm that with the garage. Could be the water pump has collapsed anyway, but will hopefully find out what the damage is tomorrow.

On the subject of belt advantages add no lubrication!
 
I'm running the same motor as a side note. 121,000 odd on the clock and first job I did was belt/pump when I got it. About 800 under budget so I just bunged some of the saving on getting it done so I wouldn't have to worry about it munching itself.
 
The 1.9 TDI is an interference engine. It's suggested to change the belt every 40K but the schedule is every 60K. The Passat I have now, had it's timing belt snap on 121k which I believe was it's second belt. Recon head was picked up for £250, with labour and parts total came to around £800.
 
nope Ford Escort Petrol, long, long ago

Many petrol engines are non-interference, its extremely unlikely for a Diesel engine to be non-interference due to the high compression required.

Try reading the thread, I've contributed all the OP needs to know bar a specific garage for him to take it to.
 
If your going to repair it then it might jst be more cost effective to buy an engine from a breakers yard and have it changed.

Thats almost as bad as the diesels don't need as much compression advice up there somewhere^.

If you have to spend £500 its worth it, as it is you have a very expensive garden ornament. Find a local independant and get it done...
:)

We had an Escort TD van in a couple of weeks ago, belt had stripped its teeth and the cam was in five pieces, including two broken caps :eek:. I didn't think Escort vans went fast enough to do that sort of damage!.
:D
 
Ditto with the ouch.

Replaced timing belt at 6 years old and going to replace timing belt, tensioners and water pump in a few weeks (at 12 years old). Gonna be an expensive year but better than the engine dying :o
 
ive been there a few times with snapping belts, had to rebuild the head and fit a few new valves. cos i did it myself it cost naff all to do. £100 tops.
