Opel Corsa 1.3cdti Timing chain replacement

    I have an Opel Corsa 06 with 80,000mls. Im going to change the timing chain because they seem to have a reputation for slipping or breaking.
    Im looking for some answers from someone that has done one on this make of car.
    I have a timing chain kit.
    I know the sump has to be removed but what else do I have to remove to get at it? and what gaskets etc will I need.

    I know the crankshaft sprocket is not keyed it relies on the crankshaft bolt (left hand thread) to stop it slipping (same as renault megane).
    I know I can lock the flywheel through a hole in the bell housing but because the camshaft sprocket has to be changed as well do I need to get the locking tool kit to keep the camshaft in position? (The obvious answer is yes.....Im just wondering has anyone done it without the extra expense of buying the locking tools)

    Any help much appreciated

    the locking kit is pretty inexpensive for this engine so I don;t see why you'd try to make something up. As for gaskets, chain kit should have profile and crank seal other than that fresh oil and filter and clean the strainer in the sump

    I have a grande punto with the same engine which thankfully is fine. The locking kit is inexpensive. It locks both cams through the side of the cylinder head and the crank, possibly through the bell housing or the crank sproket itself.

    Out of curiousity, are you getting any driving faults with the chain like engine shuddering at low RPM, or is the chain just noisy?

    No im getting no shuddering like you decribed. When I start the car the timing chain is very noisy till the oil pressure builds up and its still slightly rattly after the car starts. Since I bought the car I have read and heard lots of horror stories about these corsa diesels timing chain slipping and breaking and Im afraid that may happen quite possibly at startup before the oil pressure has built up to tension it.

    I think your 100% right to be cautious. It'd be cheaper to do the chain now than doing it along with a mashed head and valves. ;)

    Another thing that doesn't help those engines is the ridiculously long service interval originally prescribed by GM which IIRC correctly was somewhere around 18K miles. The same engine in the Fiat is only 12K. They are a good engine if looked after, driven properly, and not abused.
