407 hdi 2.0 cambelt failure

[stevie99s]

Hi just after a bit of advice from anyone that is familiar with these engines.

The other halfs step dads has snapped the belt, is it worth trying to salvage this engine or when it goes is it usually catastrophic on these?

Apparently he just lost all power and the breakdown company has diagnosed the belt, I've had a quick look on eBay and a replacement engine looks like it could be had for around £4/500.

is there any specific engine code he would need, its a 55 plate btw.

Ive got a cheap decent mechanic that could do this but we will have to trailer the car to him so he can't diagnose it really, he's talking about selling it but it will be peanuts with a snapped belt, just looking for an economical way of getting it going again if possible as otherwise its in really good nick.

Many thanks.

407's are not a huge amount of money on Flea bay, so it's worth checking to see how much they are anyway.
Don't rule out repairing the engine - you can probably do the engine all in for £1000 or so. If the engine is low mileage, then at least you know what you're getting.A 'new' replacement engine is a bit of a gamble, though should be fine.
I regularly use "1st choice spares" - had a lot of engines off the scrappers for not a lot of money generally.
The good news is, these engines are normally pretty reliable, so there will be a load of good ones about.

If it's the 8v lump, they usually kill however many roller rocker assemblies.
Retrieve the broken bits and replace them and the timing belt with a new water pump and away you go

No experience of broken belts on the hdi 16v lumps tho

It is an interference engine but apparently most of the time it simply snaps the rocker arms. You may get away with just the replacement arms...

Had one sim a while ago after dealer service!!and water pump fitting ,dont know how much it cost the dealer but seem to remember 8 rockers etc being spoken about and also a job vacancy in the workshop and a ban on mobile phone use in working hours!! it ran fine afterwards

Sledge hammer to crack a walnut?

It's a simple job to a small Peugeot Independent,don't even have to remove the cylinder head.8 rockers,cambelt kit,waterpump,a few other bits,job done.

As already said if its an 8 valve they ussually just break the rockers.
