Well I managed to grab an extra long lunch break today and changed the oil and filter. No change with the problems
Interesting that you can see one of the drums from underneath. No damage to it and nothing interesting in the sump. The Magnets needed cleaning but no chunks of metal etc. Most uninteresting!
All buttoned back up, quick test drive... no difference so it's coming out on Friday morning and then I'll strip it down over Easter weekend.
I'll keep the photos coming.
