    Hello,
    I have found that the oil filter has separated (bottom bowl from main part) the inside of the main casing where the bolt attaches too has broken off.
    And am wondering what the causes of this would be. I have been told that it may be due to over tightening or that it may be related to a pressure build up in the system.
    It is a sealed system if that helps.
    Thanks

    Depends on age and location, guessing it's outside open to the rain.

    Hello mate, no its an inside installation and the filter looked in pretty good shape apart from where it had broken.

    Might be a long shot but it hasn't been kicked or wacked with a mop ?

    Must of been some force to get the bottom part off doubt it would be because of pressure but more to overtightening and bolt inside has sheared

    Sealed system is only the water side of your heating - pipes, rads and boiler. The oil side is only feeding the burner with fuel and is only under gravity pressure.
    A photo of filter would help.
    The fact that the internal part has broke off suggests it was over tightened or the filter has been knocked, but less likely.
    Water in the oil can corrode filters and rust the bolt, but that would be obvious.
    I wouldn't be surprised if it was just a faulty filter, as the cheap filters are tat.

    If its an all aluminium cast filter which are cheap. The threads inside corrode over time because steel into aluminium does not go well, or over tightening or been tightened on the wrong thread.
    I have noticed on cheap filters before installation i opened up a few and found metal swarf which is not good for the pump. Best getting it replaced with a good quality filterlike crossland.
