The filter was cut open. It was starting to clog with rubber from the belt as suggested.
I have a new filter on now.
The garage said they can’t do the belt as they don’t have the tools or experience. I’ve tried 3 others in the area, 2 said ‘no chance’ and 1 said they’d never done it before but would try. I walked away..!
I’ve found a Ford specialist who seems to know what they’re talking about. They want £1,250 for the belt, oil flush, full clean out and new filter again. Said it’s a days work.
The garage is 6 miles away. Do you think I’m OK driving that far at low speeds to get it there? I had it recovered this morning before the oil filter was changed for a new one but I can’t get it recovered again now as they’re classing it as the same fault.
On the plus side, the engine seems fine at present as oil was getting through the filter still. Seems I stopped just in time and followed the advice of you lot - thanks very much 😄
