Longest mileage (from factory) before timing belt failure?

Tranzformer · 2020-12-05 20:30:44

Hello people,

I have just signed up and have a question I would like to ask - so please excuse me if it has already been asked.

What is the longest mileage (from factory) known on a Expert/Dispatch/Scudo 1.9L engine before failing?

The reason I ask, is that I have recently bought a Citroen Dispatch 1.9L van (non turbo) and it came with no service history. The mileage is currently on 106,**7 (I know it is due a timing belt and water pump change). So this got me thinking - 'I wonder how far these engine can go before failure?'.

So from past experience folks, can you tell me:

What is the largest mileage you peeps have come across for a 1.9L diesel engine - without ever having a timing belt change?

p.s. Whilst I am posting this I may as well ask for advice on water pump... (I have purchase the DAYCO timing belt set and KWP water pump - not yet fitted so I still time to replace it):

What is the best brand water pump to get? And is it better to have the 100% metal water pump or one that has plastic fans?

Your feedback will be most appreciated.

Thanks in advance.

back when i was running the older 1.9 XUD diesels in my BX and 306 i used the Gates timing belt kits. this is still the case with my HDI van. i always saw the metal pumps to be better, however if you live in a country where the engine could freeze then i can see why a plastic pump would be good. as it would just snap the pump.. not slip the belt.

i was always told that Gates were the absolute king of timing belts.. so i just followed the crowd i guess.

as for the timing belt, its strange i have personally known a vehicle to (not our vans) to last 200k miles on a belt before it failed. i have however heard a story of a belt that has been treated with a "rejuvenating spray" last, and keep lasting.
its one of those things, the belt only cracks with age and "weathering". they never really ware out... just get old. i can see the logic in keeping them "pliable" using some kind of belt maintenance spray preventing the air and oils getting to it.

my BX i bought at 70k miles with a snapped cam belt. the car at the time was 30 years old and had snapped 2 years before i bought it.

Thanks for the response JDM,

I know a guy who has a Peugeot Expert who doesn't really look after it, and it has 135, 511 on the clock and as far as I am aware it has never had a timing belt changed.

There is a short trip (non motorway) to do in my van (106, ?47miles) - to get stuff checked over, and I am in two minds whether to risk it or just next drive it to a garage to get the timing belt changed.

I've been told my van has come from a cleaning company who had used it as a spare van so therefore has low mileage for its age, but still... I know it needs doing asap. I'm hoping to get it fixed by the end of this week (hope it doesn't snap on way to the garage - that would be really unlucky!)

I've never heard of Gates timing belt brand before so I will do a quick search on them.

Regarding the metal fan in the water pump - I would prefer to not risk having plastic bits breaking off and damaging the engine (I am also aware that people say having all metal pump puts more pressure on the units).

Rejuvenation spray is a clever idea - wonder what is classed as rejuvenation spray. But either way the water pump bearing has a pre determined life span too.

28yrs on that BX is a result!

Thanks bro.
