One of the cam journals has some scoring on it so I’m not prepared to refit it.

It’s a BRC kit with a Fly SF ECU, twin reducers and pumped flashlube. It runs perfectly on it and will hold LPG right through the revs at WOT throttle up through 2nd, 3rd and 4th gear.

Some questions - what do you think has caused the scoring? Failing oil pump?

On bedding in the camshafts - I assume you’ve also checked the Jag forums for this engine or the 4.0 (if similar) as much wider usage in XK and XJ

No idea what caused the scoring to be honest. I’d have thought if the oil pump was failing I’d have had oil pressure warnings or noise from the top end. This one was silent and other then the misfire when cold ran perfectly.

Have you considered Kent cams for new made in house replacements ? |

These look clean maybe worth a look or more photos?

I saw those last night, they’re probably the best of the ones on eBay.

Looking at the photographs of the camshafts, personally I would DEFINITELY fit a new oil pump, that would vastly reduce the risk of the same happening again.

Good point you won’t want to sell that for a long while after doing all that!

I've been pondering the idea of the oil pump swap but to do it you need to remove the sump and to remove the sump you need to remove the engine from the car.
