Wotcha and welcome - can't help too much with leggy advice but sure someone will be along in a bit with the info, I do know from forum discussions the gearbox on diesel cars can be subject to premature bearing failure due to inaccurate alignment on assembly so opting for the petrol motor should see you right. I belive the 2.0 engines tend to be on the non turbo motors. No heard about the valve clearance check?
50k should have seen the cambelt changed so ensure that has been completed.
Keep us posted on your progress
