Renault clio
I have a small leak around my oil cap and sludge building up underneath. It is not present upon the dipstick nor is my coolant contaminated so I don't think it's my head gasket. I'm looking to buy a new cap and have spotted one on Amazon with Prime delivery but it only advertises the cap being suitable for mark 1 and 2 (mines is a 3). However, looking on Ebay i can see a cap advertised as being suitable across 1-3. Can i deduce from this that the oil cap is the same across the 3 generations of Clio's?
