[Solved] Skoda Fabia 1.4 16V 75HP - Timing change in the Skoda / VW 1.4 16V engine

Generally, I was convinced that the timing exchanged for decent components (Continental / Contitech belts, INA rollers) will withstand 80-90,000 km. That's what the mechanic once told me. Recently I took Skoda of my parents to another mechanic to look at the suspension and he said that I should make a timing here a long time, that I risk a lot, that it is "life on the edge" etc. According to him, the timing should be replaced every 60,000 km. He took off the casing and glanced at the belt, and in fact, when you run your finger over the belt, you can feel light holes (on the outside the spaces between the teeth are slightly concave). I have never checked the belt so far, I do not know if it actually means that it will break soon?

The timing was exchanged less than 70,000. km ago about 5 years ago? In fact, in these cars, the specified timing is enough for 60,000 km?

Hello. Now there are a lot of companies that produce timing belts if the belt was purchased from a company that produces inferior belts and are cheaper, this belt has the right not to withstand even 60000km.A and belt years are also important for its life. In conclusion, the mechanic was right.

On both bars, these holes. Because "professionals" can not exchange this short connecting 2 rollers.

Probably not, they are clearly visible on a small strip. It looks good on the eye (if it has irregularities, they are barely perceptible).
Before 70,000 km were listed both, I saw how old were taken off and watched them.

Replacement of the timing belt is not only the mileage passed in km after the exchange, but also a specified time elapsed after which the timing must be replaced, for example
low mileage during this period of car use.
That is, for example, 90,000 km of mileage or once every 5 years the timing for replacement.
As they say - "time does its job" ...

At the beginning they said to exchange the timing once per 100 thousand km or after 5 years now as I see that numbers like to go down .. or 60/70 thousand, I was doing last time they told me to come for 60,000 because so many belts endure and he spoke this mechanic would not exceed in this engine more than 3.5 thousand revolutions per minute. because the belt will wear out faster and it will be bad in the engine. but if you already have over 70,000, I would not risk it and I would do it in your place for a holy peace.

Now even the chains can not stand it. As to the exchange, it is best to learn and do yourself more often. It can be risked in a collision-free order and here the failure after the belt break may cost half the value of the car.

60 thousand km or 5 years. I would not do more on replacements.

I agree 100% with you and I think so too, and as the predecessor writes, it is not worth buying unknown replacements and save on this because I remember that this is the heart of the machine. Just do it yourself more often? I can not speak, and I will say that you set one spot further, you have already been splashed and overpowered. In my opinion, it is to give to the site than to do it yourself. And you can be sure that it will do well than poor and poorly depends on which service is and what opinions it has.

Each engine has a different timing change time, you have an AUA or similar 2-stripe.

Get the replacement and take the old roller straps and the coby tensioner, they certainly exchanged for you.
Take photos and paste.

Is there a way to check if it has been set up well? All you have to do is turn the shaft 2 (it's best to do 4 just in case) and if you do not block anything, you can easily connect the battery and try to start it. When replacing the belt, of course, replace the water pump if it is on the belt and the tension roller. A torque wrench is welcome when replacing.
More complicated it is only in engines in the V system and other non-typical (or cars where access to the belt is "pathological").
Here, the simplified manual for the 1.4 16V engine.

I do not know what kind of car you have (as you can write) but in this Skoda, as well as in my car, I think that 3500 turns is often exceeded

If I remember correctly, this is BBY. Yes, there are two stripes.

Of course, so much that I have already seen in my life that sometimes simple things for professionals can be more difficult than it seems for someone who does not know anything. Probably looking at how the timing is replaced by a mechanic and have a good memory after a few years can be repeated. I personally only on the basis of diagrams / description would not take such a thing as timing replacement.

A fairytale mechanic's friend tells you that this engine probably feels around 4000 PLN / min.
When traveling by bus, normal turnover is 4-5 thousand for several hours.

It also seemed to me that for example on the highway wanting such a weak engine to go faster without high revolutions will not work (I do not mention the dynamic drive around the city).

The timing is usually broken at low revs. When replacing the timing, check what is written in the instructions from the water pump box. So what, the timing can be exchanged every 120,000. as a water pump manufacturer predicts its durability at 60,000 This is the case, for example, for Dolz pumps.

Interesting, especially that once I met with the theory that the pump is replaced every second exchange of timing. Personally, I think this is an exaggeration, usually the cost of the pump in relation to the rest of the elements is not so big to risk and save on it.

Timing listed. INA set. Problem solved.
