The drama continues... err update:
Done what I said I was gona do. Oil flush kicked out a sewer. Was bad! Much cleaner now. Same for the radiotor flush.

Found a fresh symptom. Well, it's been lurking behind something else:
Operating clutch/gearselector slide we get a clear metal-on-metal grind squeal. Moving or not, sound is there. And it affects the idel run clearly as well. At times just break operation is nuff to make the engine lurch. No sound then tho.
So strongly suspecting clutch/tranny now.
Been hidding behind squeeling brakes - or so I though untill today. Yeah, been rolling a good while with that

Having limited experience with automats, abit unsure as to how check these possible issues. Is the clutch an integral part of the AR35?
If the entire box has to switched, am I looking at a complete engine pullout to make this happen?
Your invaluable insight is welcome
