Re: Timing chain Fiat Doblo 1.3 multijet

The main problem is not the chain but the tensioner bolts working loose..

My 1.3 doblo has just hit 200 thousand miles first cam chain needed replacing at 80 thou ! Then since then it's had four each one about 15 thousand miles !! We couldn't work out why ? My garage was using blue point kits and would replace them under warrantee each time ! I never got too the bottom of the problem but I insisted they used genuine chain on the last one and so far so good !! Also replaced all the rockers as recommended by fiat !! Only because if one failed it would break the chain I guess ! But it's still going strong apart from normal servicing items nothing else has gone wrong ! I look forward to anouther 50 k I hope !!

Re: Timing chain Fiat Doblo 1.3 multijet

Our chain has just broke at 90k and cost a grand to fix. Reliable my arse, this has been the most unreliable vehicle our company has owned since 1972!!! It has more problems in the first year than our previous TWO sukuki's has in 8 years daily use.

Clutch ate itself when new.
Gear shifter broke off.
Turbo actuator stuck.
Ignition barrel eats 250 keys wearing them out every few years.
Front tracking became 4k tyres wear after arm bushes all wore out in 60k
Cam Chain snapped

etc etc thats just the major stuff

Apparently the hydraulic tensioner on the timing chain is sensitive to incorrect oils, dirty oil and incorrect spec oil etc and bump starting in reverse a big no no.

Local engine services rebuilds 5 engines a week!
FIATS are a joke as far as I'm concerned and We'll NEVER have another.

Spec from factory is 5/40 but have been advised to use 5/30 C2 low SAPS by both the main dealer AND engine services, so looking into this despite FIAT originally supplying us with non low sap universal 5/40 as I believe is stated in the service book.

I'll post how I got on.

Re: Timing chain Fiat Doblo 1.3 multijet

I have worked on loads of these engines on the doblo and the Vauxhall combo and in my opinion they are a great engine . They do have a hydrolic tensioner and the reason they fail is the timing chain is not heavy enough and poor maintenance . The timing chain has to drive 16 valves , hi pressure pump and the vacum pump and its not much bigger than a bycle chain .

Yep, loads of big companies use them, post office for example, so can't be all that bad

Is this just another case of the legendary FIAT reliabilty

Surely their must be some responsibility taken by FIAT for this woeful situation

Sorry to hear that. Cam chains are supposed to last the life of an engine. In the case of a diesel at least 225,000 miles! That's the whole point of using cam chains instead of belts!
The whole reason people prefer cam chains instead of rubber cam belts is that cam belts often need changing every 5 years or 70,000 miles which ever comes earlier. More cars now are going back to reliable cam chains.
So its crazy that we are finding that multijet Cam chains actually need replacing every 40,000 miles and are actually less reliable than belts!

I'm beginning to realise that the best Diesel engines are VW TDi and Peugeot HDi. The latter is the master of diesels it uses a robust rubber cam belt that can last for 120,000 miles! A bloody good engine. Just wish I'd got a Peugeot HDi instead of my multijet

Whilst the Peugeot HDi might be more expensive, you need to remember why you're getting a diesel; to save money and the 1.4 HDi offers excellent fuel economy. The multijet offers even better economy but not nice when your fuel savings are wiped out with the cost of a cam chain replacement every 40,000 miles or a new engine because the cabin snapped! It's all about avoiding false economy and the Multijet engine is a false economy. Excellent MPG but expensive and frequent maintenance costs!

Re: Timing chain Fiat Doblo 1.3 multijet

All chain engines need the correct oil, learnt this on a corsa and other BMW's. Wrong grade starves the tensioner and chain lube feed. Can any chain under tension with no oil last? They dry up then the gears wear in a kinda hook fashion and keep hold of the chain as it goes round, hence the flapping rattling noise

I'll post how I got on.
The Multijet is pure false economy. Yes it has excellent MPG. 50 MPG urban. But what you save on buying diesel is soon wiped out by the frequent expensive maintenance costs!

OMG did they ever realise the whole idea of using Timing chains is that they are actually meant to last the life of an engine? That's 225,000 miles in a diesel at least! Unlike belts which need to be changed every 70,000 miles or 5 years. Why then did they use chains that only last 40,000 miles?

OMG how I regret getting rid of my lovely VW lupo, for a Panda. Its timing belt was in excellent condition at 80,000 miles and 14 years old ! Now I have a multijet panda that will need an expensive new chain every 40,000 miles . EPIC FAIL

So if you get a multijet be prepared to have the Chain replaced every 40,000 miles. And changing a chain is more expensive than a belt especially when it has to be changed so bloody frequently. Oh and the timing chain cover, once taken off it will always leak oil as the new gaskets and seal are rubbish.

See above, cheap garages use cheap oil and wrong grade, all non correctly maintained chain engines eat chains,
All diesels need an oil change at least every 6 months.

Re: Timing chain Fiat Doblo 1.3 multijet

@MountainRunner seems a little misinformed.

ALL chains have a design life,
his 80K miles in 14 years is a perfect example of where a chain wins hands-down over a belt.

a chain is in an oily environment,
so will not degrade when parked-up unused for extended periods,

the belt would need to be replaced ( with pulleys) every 5 years or so.
can be @ 1000 per change in some engines.

the chain overhaul is @ 800 in the GM / FIAT 1.3 engine, and would only be changed once in that 80K miles , 14 year period.

hi

I have a 2007 doblo cargo 1.3 multi jet. It's at 68,000 miles. I've had no engine issues. Do you think I should get the timing chain changed now or wait until there sounds like issues are developing ? And can anyone confirm what this "correct oil and grade" is as there is lots off talks out this being a big issue for the timing chain so I'd really appreciate confirmation.

Any help appreciated.
Dave
