@Luzern  only 40,000miles for a timing belt change ? ? ? ?   SOoooooooo Glad, I bought a SKODA !... 130.000 is the benchmark for the timing belt change... ( Skoda Fabia 1.6D  2011 reg)

Cost ?

 

Timing Belt Kit.... £94.00  (inc vat)

Water Pump ....... £40.00 ( inc vat)

Labour ....... .......£130.00 ( inc vat)

total.....................£264.00 (inc vat)

Courtesy car provided,   text messages to advise when job was completed ( same day) .

 


@shutter Overall with sevice and MOT about @RobPN 's guess. My Fabia is a 53 petrol. It's not a dealership now, but long established since 1962. Still in the same family too

No one has to agree with my opinion, but in the time I have left a miracle would be nice.

Re: Timing Belt

The garage where I take my old banger Cleo for its MOT has always had a warning / explanation notice about diesels and the "rev test". Basically if you suspect it won't take it best not to.

That is more the norm for garages as I've seen similar in a couple. Not the scare up some work notice.

I don't think it revs that hard as it's probably nowhere near the engines possible maximum. It's only the rev limiters maximum. Which isn't that high for most diesels when compared to a petrol equivalent.

As well as mileage limits for timing belts, some manufacturers also specify time limits.


^What he said.

Some cars are supposed to have their belts done every 60k miles / 5 years. OIhers every 80k / 7 years. It depends on several things but mainly the quality of the engine, how robust it was designed to be, the type of cambelt fitted, and most importantly the width of the belt. Some engines have a belt that is only around a cm wide. That's a thin belt pulling a lot of heavy (and stiff) metal around many thousands of times per minute.

Wider belts obviously have more strength and can pull more stiff / heavy metal around for longer.

Oh and as for the sign, yeah as Rob says, that's just the garage defending itself against malicious claims of damage after some other idiot tried to pin their lack of maintenance on the garage.

I need a new signature... i'm bored of the old one!

Wasn't it because cars back in the day were driven by rods to push the valves up and down and were driven off the crank so there wasn't a belt fitted. The need for a belt came in with the design of the overhead cam engine.

Re: Timing Belt

So why the need for belts anyway ?
Whats wrong with a chain ? Sure a chain can fail but usually makes a racket as it starts to fail.

Current car has a chain so can’t be much to do with engine design ?

Belts are cheaper, simple as that, chains need machinery to stamp the metal, polish, temper & rivet it all together into the required chain, whereas a belt is some type of fabric-like material moulded inside of synthetic rubber made on a big mould and then sliced up into the individual belts...

Re: Timing Belt

Belts are also quieter than chains. I had a friend who's timing chain broke without warning on his 2.4 petrol jag back in the 60s - they can fail. The result was impressively bent valve stems and broken valve guides. The rest of the engine survived.

Many if not most petrol engines now use the same type of cambelt. The only difference is that the MOT doesn't require the engine to be run at full revs at zero load. Boy racers amongst us be aware!

I was going to post similar but got distracted.  Oh yes, push-rods driven by camshafts which meshed with the crankshaft.  I remember re-building engines many years ago and woe-betide anyone who made the mistake of getting the camshaft synchronised incorrectly to the crankshaft  (2:1 gear ratio).

And then there was the joy (not) of adjusting tappets with feeler gauges!

Re: Timing Belt

Yep those were the days @RobPN I spent many, many hours blueprinting my Kawasaki Z1300 trying to squeeze every ounce of power out of it.

Re: Timing Belt

Well the latest kid on the block is electronic valves - glorified solenoids basically. Couple with electronic ignition it means that the ECU can literally shut down cylinders when not needed, fire them back up when needed, swap them round to even out the wear etc.

Apparently it's the dogs for performance too as any engine tuning / timing can be adjusted electronically so it even rules out VVT too.

The snag? - The solenoid valves aren't terribly reliable and fail quite quickly apparently. The cure? Let volvo loose on the design...

Of course we're gradually going all electric now anyway so even if it can be perfected I don't think it would be around long.

Thought about blueprinting but decided to swap the 1100cc engine in my mk1 Escort for a 1600GT from a wrecked Cortina....

I had a sort of mate who had one of those. Mainly because of the massive set of pipes that went with the six cylinder engine. He showed me that one of the exhaust boxes was a fake.

He was quite open that he likes travelling to Europe frequently so you can probably guess what the exhaust box was used for. He even said that the job he had was basically just for the taxmans benefit as a sort of explanation of where his money was coming from, or not.

And.... of course,.... you told your insurance company, about the "modification"... and they increased your premium, accordingly ....
