Hi Adrian,
Thanks for asking, Albrecht kindly came today and we had a very productive and educational "for me" day! Thank you once again Albrecht, so very grateful!
On removing the oil pan we discovered a broken washer and as we removed the timing cover a small bolt fell out . It's head had been rounded off really smoothly and Albrecht realised that the bolt must have made the groove in the head, we insered it into the groove and it fitted perfectly. Pics will follow soon but basically the bolt must have got stuck between the timing chain and the chain guide, as the chain moved round it was spinning this bolt round and smoothing it out.. The timing chain is very shiny too - which makes sense now. As to how the bolt got there in the first place is a mystery since all the bolts within the engine are present, and this bolt is too small to be an engine bolt. It could have fallen in when someone had the valve cover off or possibly the oil cap.
We removed the head and the valves look in good shape and so do the pistons and piston bores, so that's a huge relief .
From what looked like a complete rebuild looks as if I have been very lucky... How that bolt didnt get stuck in the lower pulley and jammed the timing chain is a bigger mystery to me then how it got there in the first place!
I've got quite a bit of work ahead of me now.. but looking forward to it!
