No, I haven't checked the camshaft O rings yet. I'm going to whip the valve cover off again and check the phasers and O rings.
Is replacing these O rings a job you've attempted yourself? I'll have a go at most jobs but these O rings fill me with dread as they look as if they need to be stretched quite a bit to fit them?
I see you're located in Midlothian. Is there a good mechanic in the Edinburgh area you trust with your Mini? Thank you.
