I am replacing my timing and injection pump belts etc, and find that when checking the alignment of the LH camshaft when the crankshaft is at TDC, the mark "OT" is visible in the oil filler cap hole, but the slots at the rear of the camshaft will not line up. Am I being given the correct information?

Also, is there anywhere I can get any accurate repair procedures for this engine - I am relying on Autodata info for this particular reapir.
