hey , yes you will require top and bottom cylinder gaskets that is about all.
by the looks of the rings there is a chance they are causing the issue , ive replaced rings in better condition that have caused issues, your symptoms and previous diagnostics's points to them.
cheers mitch
Thanks Mitch, just thought i'd ask the question since i have now taken the machine apart so if there was anything else i needed to do eg bottom seal then i' d do it now without having to dissassemble later.
