'Great Diesel Myth'

If its not a fiat or a rover k series and you don't drive like a spanner Should last Tbf....also don't diesels have those too? Could have sworn my sisters bfs Audi 1.9 tdi died due to a head gasket failure..

The only time a diesel can cost more than the equivalent petrol engine to look after is when you have a DPF :bang:.

Correction, when you have a DPF that fails, mainly because your a tard who does city driving and opted for a DERV.


What about headgaskets on petrols ;)

Or Diesels. HG's go on both.
 
I've seen them fails for people doing 'average' mileage ;). They where however getting on a bit so I doubt they push the throttle too hard :rolleyes:.

That's the thing I like about petrol engines :) as long as you don't thrash them and you maintain them properly then there's less to go wrong than with a diesel :) Other than coils, leads and maybe a sensor or two, I doubt much will go wrong with the engine on our 500 during its lifetime :)
 
Just because it a petrol doesnt mean theres less to go wrong.

In my driving life i've owned 5 petrols in 5 years, all have gone wrong. including my 09 Grande Punto which i only bought 2 months ago which is going in under warrenty for a gearbox.

In that same time we've owned 2 diesels in the family, neither have even missed a beat.


Making up your own statistics and saying just cause its a diesel it'll go wrong is false. Show me some proper research and i'll retract this.

But its common knowledge that other than the EGR that FIAT Deisels in FIAT/Vauxhall's are more reliable than the petrol counterparts.

I don't quite get your reasoning. The DPF presents a great and rather big danger. You've also got the added complexity of a turbo and an EGR as well. EGR's on 1.3 MJ's are renowned for clogging up and a few people on the Panda section have had sticking wastegate actuators.

Obviously how well a particular petrol or diesel engine does in terms of reliability and/or design. A badly designed engine with poor quality bits bolted on will be unreliable regardless of being diesel or petrol.

My 406 turbo diesel did two head gaskets but I'm not going to use that as hard and fast evidence of diesels being worse, it's just that it's a big problem for the 1.9's and I bought a compete sheetheap of one.

I've owned owned 4 petrol cars (A Fiat 131, a Peugeot 504, a Fiat 500 1.2 and a Panda 4x4 1.2) and other than the 131 burning oil (it was 25 years old ffs!) I've never had to do anything other than regular maintenance.

The wifes Scooby is an L reg and in the 6 years I've lived her, has needed a coolant temp sensor and recently needed the idle air control valve cleaning out to pass emissions. For a car of that age that's pretty good.
 
petrol cars have turbos too

with pug diesels you have to measure piston protrusion to get the right gasket, many just count the notches on the old gasket and fit the same, that is why they go again soon after. ive no idea how piston protrusion changes but it does unless they all had the wrong gasket from factory

I dont get your reasoning either.

You state just because a deisel is more unreliable than petrol. I was wondering what your research is?

The DPF works in a similar way to a CAT but isnt present on all deisels. I dont think the 1.3's have them. Our 1.3 MJ Corsa certainly doesnt

Why does the turbo make a difference, every deisel has one, they wont work (well) without one.

I'd much rather own a deisel over a petrol, but couldnt find a good enough spec'd one to match that 1.4 Petrol i bought.

They don't really work in the same way as a cat tbh, the car doesn't trap carbon monoxide and then inject extra fuel to catalyse it into CO2 and other stuff :) Personally I'm of the belief that if you're not a complete moron then a DPF diesel will be fine, but I'm sure you know that the world is sadly riddled with morons who will drive DPF diesels short distances and/or not change the oil when they're meant to.

The point I was making about the turbo was that it adds more complexity and logically something which is more complex will be more prone to failure.
