Skoda 1.6 tdi timing tensioner failure Part one

This week was interesting. Having replaced this belt a couple of years ago on a Skoda Octavia 1.6 Diesel,the customer came in with a terrible noise. So it was time to investigate. As you can see from the pictures upon stripping it down I was horrified by what I saw.



As you can clearly see the bearing as totally failed. It was surprising to know this car was actually running. Totally amazed that it was running. 






You can see that the heat from the faulty bearing has over heated melting the plastic on the tensioner. Here you can see it after removal.







The obvious thing to do now was replace the timing belt kit using the correct Volkswagen  locking tools to see how it runs. OK so I will put you out of suspense. The car runs but makes a terrible noise. So unfortunately for the customer the Skoda will be stripped for further investigation. I have no doubt there will be internal damage but I expected this anyway. 

I will follow up with this in a future post and will try and add a few photos too. Please feel free to comment to contribute to this blog. 

So, this has been an absolute nightmare. After removing the cylinder head, which is a huge job that’s time consuming and difficult. I checked all the valves and to my amazement there was no damage. So  it was time to rebuild. After completion I started the engine. Then ping engine MIL light illuminated with a horrible noise. 

My moral for the job was fading, really frustrated and beginning to doubt my work. After checking the fault codes it showed a timing correlation fault. 


So I stripped it back down AGAIN!! And rechecked my work. As you can see everything timed up perfectly. 





So what next?  It couldn’t be the sensors, the only thing it could be was the timing.

PSA 1.2 Puretech oil pressure fault. P15a8.

f you own a car with the PSA 1.2 Puretech Engine then this post is for you.  This engine is fitted to many vehicles including   Ford, Peugeot, Citroen, and Vauxhall’s  It has come apparent that these engines fault at about 40k miles.  The symptoms. 1. Upon almost first few accelerations from setting off the engine light comes on.  2. The vehicle odometer near 40k or multiples of.  3. Flagging fault P15A8 on diagnostic tool. This is a oil pressure fault   The problem.  This engine although a good engine with some fantastic technology built in has a timing belt that is inside the engine.  This may have seemed a good idea to the designers but it deteriorates in the engine oil, flaking off and clogs and blocking the oil pick up. If left could end up in major engine failure.  The solution.  Quite simple really, remove sump (easy task) check and clean oil pick up. Then change cambelt. Quite a Job.  If you want to see how to diagnose and solve this on your psa 1.2 Puretech Engine i have made

Vauxhall vivaro and movano knocking or banging noise on front.

I have recently experienced on the vauxhall vivaro and movano on two occasions these models have had a really bad knocking or banging noise. After initial inspection nothing has been found.  Firstly, It’s worth noting at this point that these models are prone to the front top suspension mounting collapsing. This can be simply be diagnosed by looking at the top mount under the bonnet. If faulty the will be a significant gap and it will also be slightly offset. Not central. After inspection this is what happens to the top mounts. Secondly, If this is not the cause of the noise and after frustration trying to find find the noise it is worth checking and tightening all the subframe bolts and wishbone bolts. These may appear tight and show no signs of wear. Once completed road test and listen. Hopefully now the knocking will have gone.
