My girlfriend has an 06 Sport Hatch 1.6 SXi. We took her car for service and they told us that the sump thread is split. They managed to tighten it and it isn't leaking for now but this brings me to my question:
Is it really worth buying a new sump just yet if nothing is wrong? I know it will need replacing but I'm not sure whether to risk it further by leaving it. How important is it to change?
Any answers to this greatly appreciated. Thank you!!
