VW Polo 1.2 T/chain tensioner

    2004 Polo 1.2L. Very low mileage and unused this past year, apart from a trip to the NCT centre.
    I've read the timing chain tensioner is a weak point so I think I should replace it - with an OEM part.

    Is it a straightforward job? Easy to access under the timing cover without more dismantling?
    Will I have to remove the upper engine mount to remove the timing cover.
    (Looking for a Haynes manual if anyone has one to sell)

    Thanks

    Is your car a 6 valve or 12 valve? Yes you will need to remove the engine mount. There is an upgraded timing chain kit available from a few quality spurious manufacturers. New guides, tensioner, cogs and bolts. Quite reasonable. OEM kit is stupid money.

    12valve I think. It's my sister's car. The mileage is so low I was only planning to do the tensioner, not the full kit.

    I thought the issue with these engines was more down to incorrect oil viscosities being used and frequency of oil changes, i.e. the small holes in the tensioner blocked with sludge and caused the tensioner to fail prematurely? Because of the VW Longlife service interval? Am open to correction...

    Thanks. Sounds plausible but I've not actually read of any case of that - yet!. I've read posts saying the tensioner was upgraded but I haven't spoken to a dealer for confirmation. The guide rail is now longer; to help prevent the chain skipping a tooth.
    I know oil changes on this car were done regualrly. I'll check the viscosities when I see the service records.
