Right, it seems as though I have to do my head gasket, and therefore, I think i'm going to tackle it myself with a mate who is a mechanic but is there a little guide on how to do it as I always feel these help? - I am thinking of doing the stem seals whilst the head is off, cambelt even tho it was done at 99k km and water pump, is there anything else that would be a good idea, and where could I get some uprated stem seals from? - As these are non- interference engines how does it work in regards to getting head skimmed and thickness of head gasket if i want to keep it non interference, I take it it is best to skim the head even though the car doesn't appear to have overheated as yet? What head gasket will be best to run 1 bar ish on TD04, I hear Athena, and where would i get one of these from? Finally is there anything else I need to beware of, for instance i think i've read before theres something you need to do when removing the cams to stop a spring coming loose or the engine will rattle or something?
