Cambelt Paranoia

[Gary406]

Just drive it normally, dont rev the nuts of it, espec when cold.

does that matter ? i thought if its gonna snap its gonna snap

1k revs or 7k revs

Actually the most common time for a belt to snap, by far, is on start up. The owner assumes an engine stall and cranks the engine again........Oooops

[no2lurch]

why is there a belt used to drive the cams, wouldnt some mechanical system like cogs or the thing old locomotives used for turning the wheel be better.

surely a load of cogs would have more resistance, sapping power from the engine. chains still stretch and need to be changed, just less often.

Ford's Essex had a gear to drive the camshaft (made out of plastic ) Aircooled VWs too, there's probably quite a few. It's not so easy with overhead cams though... (Mad Italians notwithstanding)

There seems to be a trend of a return to cam chains recently - I've heard of a fair few on modern engines (I think the Honda CCTTDCDDCCTi has a chain?) I suppose they've developed lighter, stronger, quieter chains of late. Also isn't a cam chain kinda 'in' the engine so benefits from all the oiling it wants?

[steve_earwig]

Honda?!! They've always been well known in the biking community for licorice cam chains that eat through crankcases Hopefully they've improved them, cam chains in general used to need changing about as often as a belt (or they'd get as noisy as hell, eat through casings and eventually break, with predictable consequences). At least a belt is easier to get to...

On the topic of the honda icdti, where did they get that from, for all its life honda has made petrols, did they just single handedly make a brand new diesel engine all on their own? And them accords are meant to consume quite a bit of oil, but unfortunatley i have to say it seems like quite a decent engine and them accords are quite a nice solid car.


lozz that merc is one from the time when they were knowm for the faults, nice car but probably more unreliable than a peugeot, the c class before it got away ok just with rust issues.

Say it isn't so! I've done 74K on my CB and it's still going strong! (Touch wood)

.........still don't park it near anyone though

Waste of time, welly. They'll all know who's it is by now.

Have a good weekend!

He heeeeeee

FarmerPug - Honda did indeed make the icdtiddccddtti all on there own and my only remotely interesting fact I know about the thing is that it doesn't have a separate Head as such i.e. the engine is a sump then the block+'head' are one piece and inseparable, kinda.......I think it was a way of reliably holding high compression and boost without the 'weak spot' of a head gasket.

I was checking out one of these, "I Can't Design Turbodiesels, Iriot" jobbies last week....

Defo failed the rice-pudding test IMHO

[FarmerPug]

whats wrong with them i was in an accord ctidtdidi and it was a nice and smooth engine, a bit less powerful than what i would have expected from a 2.2 but not a bad car.
so there is no seperate head? is this some sort of long bolt engine trying to be the diesel equivilant of the k series?

[Welly]

The Accord is still expensivo when I had a tentative look at them

You tend to get offerings with star-ship mileage and an Audi-type price tag

Mr Fonz wants to say hello.

[FarmerPug]

the accords are an expensive car, hondas always are but this isnt really stupidly expensive:

Tbh I'm probably remembering from my early days of biking, about 25 years ago but they certainly had that reputation at the time.
