Not exactly top of anyone's lotto list obviously like, but for what they are I haven't heard many complaints?
From an engineering point of view, or whatever point of view you like, give us an ol summary of what makes them unmitigated balls of shyte?

That's because the 3 quite simply does not give problems, the same as every other Mazda apart from models with their in house 2.0 diesel. The 1.6 diesel needs to be serviced on time all the time, but then again any responsible owner does that with every car they own anyway.

I've been a long time lurker and Nissan doctor has always from what I've seen given sound advice.

I myself am an engineer and can guarantee that Nissan doctor knows more about this than I do. In my field I would say I know more than him however.

So sometimes, just sometimes a mechanic knows more than an engineer.

Sometimes.

Are you an engineer because if you are then you're damaging your own statement as you clearly don't

i do apologize ,,,,it was a broad statement ,,,and it was from personal experience , the 6 is a cracking car,again,,,id be wary with the OPs one

i totally agree with you,,, but if people actually read the thread, we wouldn't be having this conversation

So we are agreed then

The Mazda 6 Timing Chain will last the life of the engine as long as it is changed at regular intervals and a mechanic sometimes knows more than an engineer.

What if the engine packs it in because of a non timing chain issue and i change the engine should i then need to change the chain.....

Discuss.....

No, that's more or less the opposite to what we've been saying actually.

The chain does not need to be changed at regular intervals.

Read it carefully its a contradictory statement,humour intended

I understand that but I assumed along with your initial OP that you were looking for serious and accurate replies.

clintondaly

So all i have received is serious and accurate replies

So i will change the chain ?

Oh,i shouldnt change the chain!

its turned out to be a conversation with some good comments between everyone else,which i have enjoyed.

No the chain will not always last the life of an engine, , and its not changed regularly, that would be a belt, once is enough if ever, to change a chain ,,,,,,,,, if its required.

A mechanic never knows more than an engineer.

If the engine packs in, the Mazda isn't worth going to the expense of replacing it , but changing the chain on this hypothetical engine, again, depending on the mileage of said engine "I" probably would.

I have the 2.3 MPS and that has a chain too. In the MPS the chain can stretch and needs to be replaced. It doesn't happen in all of them though and hasn't happened in mine.

:D:D Seriously, unless the engineer in question specialises in the area of engine or engine component design then there are very few aspects of the training, standard or advanced, that a mechanic/technician goes through that crosses over with an engineer and vise versa.

One of the main things sited as a cause of stretched chains on modern engines is people letting the engine run low on oil, this causes excess friction and thermal expansion of various parts, putting extra strain on the chain, so in short, again, its generally a maintenance problem.

Also, the vast majority of chain issues on modern cars are actually due to faulty/poorly lubricated tensioners or poorly manufactured sprockets.

Thats a whole new thread.
But an engineer could change the oil and plugs in his car ( or many other things but this is just an example), can a mechanic design and build stuff ? no, because his/her role is basically to take out an old/worn part and replace in a new one.
Diagnostics are done for the mechanic by computers (built by engineers) so its not all that hard really

I know many engineers who wouldnt attempt to change oil or plugs. A fair few of them would have no mechanical sympathy and even if shown how to would be not at all inclined to. Also computer diagnostics won't tell the mechanic the likes of where the coolant leak is, where is that vibration coming from and any amount of other issues.
To suggest that an engineer always knows more than a mechanic as a blanket statement is nothing short of retarded. Mechanics rebuild engines etc too, its not all replacing filters, brake pads and using diagnostics.

MetzgerMeister

A lot more is learned in the field by working with engines ever day than you can learn from books and exams.

Wow, that's ignorance on a whole new level. Oddly, that comment shows a monumental lack of knowledge on the area of modern vehicle diagnostics, which is strange, because your an engineer!:rolleyes:

In my experience, engineers are about as useful as " **** stuck in the neck of a bottle"
I used to teach a class specifically for engineers which (I'm not joking here) was supposed to teach them which end of the screwdriver to hold, which end of the hammer to hit stuff with and that knives.................wait for it........are sharp!!
Luckily enough I had a real job where i was required to fix stuff for a living before I became one of ye muppets;)

You say that once is enough if ever to change a chain, how does that make sense by your logic? Say you change the chain at 150k as a precaution surely you must by your logic change the chain at 300k then?

Mechanics are specialists in their chosen field and not gombeen men. In fact mechanics often spend their time fixing cars that have design flaws that have been caused by so called engineers that haven't a clue how things work in the real world.

.... we're gone from his extreme to yours now. In fairness a decent proportion of engineers would have a mechanical aptitude and can certainly use basic handtools.

Yeah, you're right, that Reply was a reaction to the type of engineer who's posting here, i know the type only too well, arrives in from college, waving a piece of paper, thinking they are the only person in the world who knows anything. It normally takes about 6 months for them to figure out that we managed to run the place before they arrived.

Anyway back on topic, i know nothing about mazda timing chains:D

yes , he cant make up his mind who to troll,,,spot on with your view on engineers, may they be mechanical or whatever, although, civil engineers are a thorn in my side

Dr.Rieux

I wouldn't trust a mechanic to design a bridge, nor would I trust many engineers for that matter, depends on their speciality. At the same time I would trust my car with a mechanic rather than an engineer

The only arrogance ive seen here all week on this thread is coming from you sir,
Especially when you consider, for all you know, i could be the guy that trained you.
it seems everybody's opinion on anything mechanical is wrong, but the good doctors advice is gospel, because a mechanic has never being in error.

And yes, i am an engineer, old school at that, so contrary to popular belief on this thread i actually do have hands to wipe my ass, as the old saying goes.
