Mechanic suspects that the cars timming chain is not timed/aligned. Is it possible to time or align it without having to replace the entire belt? 

 

He want to try to align it with a timming kit. 

 

 

Pardon my english

Is it a belt or a chain, what engine does the car have?

 Chain 1.4 TSI petrol

If has slipped out of correct timing something is either very worn or broken or has someone had it apart?
What's a timing kit, it is usually timed by aligning marks on pulleys.

Agreed; the last time I looked at a timing chain, a 1 tooth jump would be several degrees, and I'm surprised the engine would run at all with the camshaft timing that far out.

So I guess it might be a slight miss alignement?

Not sure if the engine is the same but my daughter had a VW Tiguan 1.4TSI with a timing chain that had slipped - apparently it can happen if the car is left in gear and is pushed / rolls backwards! Common problem. Two garages she went to missed the diagnosis and although the engine ran - it was rough. Eventually it slipped another tooth and wrecked the engine - valves hit pistons etc. and the car was declared a writeoff.

 

My advise - don't drive it until somebody who knows what they are doing investigates and physically checks the chain and the timing.

I have read elsewhere that the 1.4tsi with timing chain has the same inherrent problems as the early 1.2tsi. Normally the chain wears and jumps far enough when it happens to completely upset the timing, and as the engine is an inteference design where pistons and valves occupy the same space at different points in the engine cycle, destroys the engine with pistons hitting valves. If yours has only jumped one tooth and is saveable you have been very lucky. If so you urgently need to get the timing chain replaced with the heavier duty version brought out after the spate of failures and retrofitted to the relevant cars before they failed, following the early signs of rattling etc.

I would strongly suggest you do not use it again until you rule this out as a cause.

 

The above where turning the car backwards overcomes the tensioner and jumps a tooth is another possibility that is not so concerning, but the car should still be fixed before further use?

Replacing the timming chain has relaxed the fuel pressure valve. Now the car is very smooth and has more power 

Thanks everyone for helping and sharing your experiences. 😀

I did purchase an aftermarket. Because the prices was 50% for the genuine offered at skoda authorized dealer.
