Car towed in by RAC suspect cambelt snapped. Removed covers and belt is ok. Removed rocker cover and found that inlet camshaft is not turning. Suspect rear timing chain snapped. Looked impossible to remove rear chain cover in place so took head off. Removed rear cover and found chain snapped. Unable to see any timing marks for aligning timing chain. This seems to be an odd ball engine and only genuine parts available.

Any help in finding out info would be good.

THANKS
