    I have a 83 chrysler T&C with 2.6 Mitsubishi engine. I bought the car
    new, exported the car to Europe 5 years later and used it ever since
    (as a second car). The car has driven more than 150.000 miles without
    problem, until a few days ago. First a small rattling noise (timing
    chain??), the next day engine warning light on (after cold start
    indicating probably oil pump failure?)
    This car, although common in the US, is a one of a kind in Europe.
    Hence my attempt to keep it running for another 20+ years. No dealer
    or repair shop in Belgium has ever seen an engine like this. So I'm
    on my own to repair this myself (with the help of a friend of mine).
    I have a Chilton repair manual (not very helpful for this), but no
    detailed factory repair manual.
    Can anyone help me with more detailed info on the timing chain or oil
    pump chain? How to replace it? Would replacement of chain guides
    only be sufficient? How to get access? Are there some shortcuts or
    pitfalls? Pictures? Schematics?
    I've been trying to locate a factory service manual on ebay, but this
    would take 2-3 weeks to receive it in Belgium.
    Can anyone help me with a digital copy of relevant pages of factory
    manual on timing chain and oil pump change?
    If anyone could help me with this, I would really appreciate this.

    IF the chains are worn and the guides shot, the chains, tensioners,
    and chainnguides must all be changed.
    Sometimes the engines get noisy all of a sudden if the tensioners
    Try a flush and change to 20W50 oil and see if it quiets down. If not,
    you've a lot of work ahead of you.
    The countershaft bearings also can get "tight" causing the oil pump
    chain to break or the sprocket to strip.

    The chain case can be removed from this engine without dropping it out
    of the van. I have done it myself to replace broken guides. The trick
    is to undo the front centre mount and support the engine with a jack.
    Remove the passenger front wheel and inner fender cover to engine.
    Then jack engine up a bit to remove the upper chaincase bolts, then
    lower it a bit to remove the lower bolts.

    It's been a lot of years, but my Dad had one. His oil pump chain came off
    while he was out in the desert, so it wasn't very convenient. I don't really
    remember why it failed.. The chain guides rub all the time, so they'd
    naturally be worn out badly on yours. I would think you'd want to replace
    the chain as well. If for no other reason than it runs the oil pump.

  6. I had an 87 that had that engine or at least it was a Mitsubishi 2.6.
    As I recall, there was a port on the front of the chain cover to
    adjust the tension on the counterbalance chain. Had an access hole
    with a cover in the front wheel well. supposed to be done every 30K
    miles. However, chrysler corp failed to list the adjustment in the
    owners manual along with all the other periodic maintainance.

    It got loose and went everywhere. I do remember being able to replace
    the chain without taking the engine out.

    I complained to chrysler about the failure to warn. There answer was
    they would have paid for it if I had taken it to an authorized dealer
    and not done it myself. Easy to say after the fact.

    You might look to adjust, see if that stops the noise.
