Timing chain

[benbou47]

Hi there

I want to ask about a trick mechanic are doing in my country to prevent timing chain skipping in fabia 2 in case Hydraulic control chain tensioner failure due to low oil pressure by adding a piece of metal to work as a stopper for Tensioning rail as you can see in the picture

Can’t see a problem with that , it looks like a good idea 👍

Nice idea.

Perhaps a limiter like this is something VAG should have fitted originally, rather than relying solely on hydraulic pressure. 

[Breezy_Pete]

The tensioner on the HTPs doesn't even have any sort of ratchet mechanism, just a spring to do the job before oil pressure builds at start-up.

[J.R.]

When tensioners have a ratchet mechanism there it still allows some degree of fore and aft movement for chain oscillation and to reduce wear on the chain guide pads, the one shown would work but should be carefully set to allow clearance and would need adjustment throughout the life of the vehicle to remain effective.

 

But I do agree its a good idea and applaud the guy!

It's several hours of work to remove and replace the chain cover, so not going to get adjusted unless by a wildly bored retired mechanic, and TBH they wouldn't have a car with one of these engines.

My sister is about to buy a 2013 Fabia 1.2 litre petrol car. Does this engine have a belt that requires replacement?

@SandgroperIt has a Chain if a 1.2 TSI.

The belt 1.2 TSI is introduced in the Fabia Mk3 from 2014 until those were dropped and they got the  1.0 TSI with a cam belt.
