Re: VW / Skoda 1.8L TSI: When to replace the timing chain? For the benefit of those with 1.8 TSI engines:
The first symptoms of chain slippage would be usually a minor hesitation or unusual noise during starting. There will be no warning lights. Usually after this initial symptom the engine starts and runs without any apparent problem. During any of the subsequent starts, there would be a larger hesitation while starting the engine. It is at this time, the major slippage / tensioner failure happens and warning lights would come on. By this time the damage would be done.
There are two ways to go about this:
1. If you are able to recognise the initial hesitation / unusual noise during starting it is best to take it to the ASS for a check up of the timing chain. Since there are no warning lights, they will tell you nothing is wrong. Insist on having the engine opened and checked. You might be able to get away with a faulty hydraulic chain tensioner failure and have the complete timing chain kit assembly replaced thereby avoiding major damage to the engine.
2. If you are not able to properly recognise the hesitation during starting, you will know about this issue only when the engine stalls and the warning lights come on. By this time, unfortunately, there would be more damage to the engine.
What you can do to reduce the probability of this happening:
a. Avoid engine mods that lead to engine power increase.
b. Avoid using the car as a predominantly city commute vehicle.
c. If your use is majorly city commutes, reduce the oil drain interval to 7.5K.
d. Maintain oil at or near max levels always. |
