here is a rare cause:

the right cam sprocket is not engaged with the cam

- either cuz a pin was left out or sheared - loose bolt/nut, or it just stripped cuz the cam seized for some reason

absolute worst case - "somebody" tightened the cam nut/bolt with an impact wrench - it can crack the cast iron & the nose can simply break off after engine starts running -

yes - i did that once about 25 yrs ago on the first engine i ever worked on YIKES

the seized cam - stripped sprocket event happened to me once when oil line got ripped off when wifey ran over a concrete divider one dark nite in Pocatello - engine ran a couple miles before it ran out of oil on one cam and it seized

- she said it had no power those last few miles - the red light did not deter her from driving onward
