    All the cages I've seen have the cams running straight in the head.

    There is an oil feed to each journal, so the cam runs on a film of oil at all times.

    Doesn't usually cause any problems, but can seize up due to lack of oil changes, but this is very rare.

    Only on alloy heads,cast iron heads use shell bearings.

    If changing cams I would consider checking them for wear, and also checking the cam lobes for profile and height.

    Pitted cams

    When the GB was apart at around 50,000 the cams were pitted. I just put it back together and forgot about them. 35,000km later they are still all together and I don't want to look. New cams cost as much as it was to bribe Saddam.
    I have just found out that they have removed the word gullible from the dictionary
