Faulty Camwheel
This has been the source of all my problems. The key had not been located properly in the exhaust camshaft slot. You can see that the key has a step in it and when the key slipped out of the slot then drama! I don't understand how anybody could achieve.
this but sure has caused me a lot of problems |

Probably by believing that they didn't need the specific service tools Fred.

This could occur with our without the service tools IMO. The key on the wheel and the slot have no gentle lead in to assist assembly, and I would imagine if the installer was not too careful would occur. A quick check after fitting and cross checking the relative position of the pulley would have caught it. Once fitted when turning the engine over by hand the runout out the pulley would have been significant and would have been hard not to miss.

I would imagine that it would put the timing out by a tooth or two also.

It can be difficult lining up the key, particularly if you are working alone and it may be even more difficult without the tools. (Not sure about that as I have never tried it myself.)
I agree with Lovel that the pulley would be obviously out of plane and would certainly give the problem away with a wobble once tightened up. You were very lucky that the pulley didn't slip. That could have been expensive. Glad you found the problem before bad things happened.

There is nothing wrong with the cam wheel. It is thus not "faulty"! The headline should reflect that. I suggest "Faulty assembly of cam wheel"
