Hi all,
Just fitted new plugs to my Fiesta (1.25L Zetec) and noticed that the plug for the cylinder furthest from the drivebelt (passenger side) had a fair bit of engine oil on the threads (but none on the firing tip). There was no oil around the plug hole. I think this might tie in with why it's been drinking about half a litre every 4-6 weeks since Ford did a cambelt change in August IIRC :/ There doesn't appear to be any mix of oil and coolant.
Is it likely to be head gasket leakage or piston rings? Do you think I'll be able to get Ford to fix it (for free!) ?
Is there any point in getting hold of a compression tester?
Thanks and have a good new year!
Peter.
