The oil light came on the other day on the Wolf. It went off when the engine was revved. Checked the oil level and it was fine. The oil was ready for changing anyway so bought OH the oil and filter in case the filter was clogged. All changed and oil light still on. Next off came the oil pressure switch. It had oil showing in the back bit so looks like that's the guilty bit. Went back to Minifords car shop in Crewe. He has two of the three types of switch in stock. Of course we needed the third type. Saw him this morning, he got one in for us this afternoon. Just an electrical connection and screw it in place and the light is off. All ready to go again. Very Happy
