  • What is this build up at number 4 cylinder all about and why should I worry

    Well as the movie quote goes, if its happenning (and it awlays does to some degree) be afraid, very afraid as cylinder 3 and 4 are not being cooled by fluid and only latent heat transfer and we all know what happens to aluminium chapes when they are not heated/cooled uniformly right. Top maeks if you say warps !

    There are many dangers of warping a Hillman imp engine, not all are evident immediately, many hide in plain site.

    Here is the nastiness we speak o in all its naked glory !

    And no there is no way to clean this properly other than remove the head and get in there, it is a back breaking contortionist neck breaking jobb to do in the car, pull it out !

    Remeber when done, cgeck the block and liner levels, no point wasting a £35 gasket set on a warped block it will only fail early and perhaps take your head with it !

    Sometimes an ugly picture can say a lot !

    So the burning question is why the build up?

    Knowing the why mat help to prevent it. ;)
