Managed to change the oil filter, lots of faffing about, both my filter wrenchs were useless so in the end took the housing off, The oil was like black water. Must get me one of those three leg wrench looks to be ideal. When jacking up the buggy I noticed that the radiator side engine mount is broken, the rubber is still ok but the metal has broken. So gonna change both tomorrow. Hopefully then I can get it running.
