I'm so lucky !

Just before I went on holidays the car went belly up on me (another reason I wasn't posting here...dragging the pool for excuses now haha)
I started her up and heard a bit of an unusual rattle but drove on regardless, she was a bit sluggish at first then there was an almighty rattle from the engine and she died.
I left it with my mechanic Robbie while I was on holidays, it seem the pre-tensioner had gone??
He showed me these two pieces of metal that were once held together with ball bearings, but weren't anymore.
He also changed the timing belt... a few brake pads......filters etc
He said I was lucky it wasn't a new engine.
Whole thing cost me €800 ...........heaven help me when I get unlucky!
