Had a message from my father in law asking me to highlight a very expensive problem to other owners. He worked as a mechanic and breakdown repair specialist for over 30 years so he knows his stuff when it comes to car faults. This is the information he has asked me to pass on:

My mother in law owns from new a Fabia 1.2 3 cylinder 8 valve year 2005 which now has 60,000 miles on the clock.

The engine started to lose power over a very short period of time.

A diagnostic check was carried out and showed coils, injectors and running gear all working normally.

An in depth gas analyse check was carried out on the engine which found that each cylinder was down by 30%.

On removing the cylinder head it found that 3 exhaust valves and guides were worn out and there was cracks on the exhaust valves.

The head was sent to a specialist engineering firm for repair who have informed my father in law that this is a common fault with this engine on the Fabia.

The rebuild has cost a lot of money and Skods UK were contacted but they deny any problems.

Just letting potential owners know about the fault and to look out for it in their own cars.

Hope this information helps.

One question,

How does 8 go into 3?

With remainder 2!

Skoda VAG (given some issues that can my Polo, it seems VAG in general would be a fairer thing to say) seem fond of denying common issues it seems. . .

cylinder 1 = 2 Valves

cylinder 2 = 2 Valves

cylinder 3 = 4 Valves

Cooooorrrrr its not hard

cylinder 1 = 2 Valves

cylinder 2 = 2 Valves

cylinder 3 = 4 Valves

Cooooorrrrr its not hard

how do you find out if your engines 8 or 12 valve mine a 1.2 3 cylinder but dno about valvles its the 54bhp classic model ? any ideas ?

it will surely be either 6v or 12v ?

it will surely be either 6v or 12v ?

You'd have thought!

Timing chain wears on them aswell resulting in the chain jumping

6 valve on 54. 12v = 64bhp.

lol so hard at this thread.

You have to question the integrity of the information when the OP thinks a 3 cylinder engine can have 8 valves.

Common to them might mean they've seen 50 of them. Out of the thousands of cars produced, that wouldn't be a bad innings.

If there were valve damage, it could have been the timing chain? Are the 1.2's OHV or OHC?

Take the plugs out, wedge some Edam in the holes and if it melts its a 12v if it does not melt its 8v

cylinder 1 = 2 Valves

cylinder 2 = 2 Valves

cylinder 3 = 4 Valves

Cooooorrrrr its not hard

I forgot to mention, cylinder 3 has 4 Valves, which means 2 extra valves.... this is what give you the V-tec felling at 6k

so theres no such thing as 8v ? is mine the 1.2 54bhp the one with the comon problem thats all i wana know

I've seen some of the 6v 3-pots with stretched chains. You can usually hear the chain rattling about.

Sometimes the guides have excessive wear too. That combination of faults can cause the chain to jump teeth. That is usually obvious too.

If you ignore the warnings and continue to drive, you can get damage to the valves.

Can a 1.2 54hp get to 6000 revs???

Yeah boi, it can get to 12k if you open it up

Yeah boi, it can get to 12k if you open it up

Lol
